Abbreviations This information is included in Appendix A: Abbreviations , which includes all abbreviations and acronyms used in the Factbook, with their expansions.

Acronyms An acronym is an abbreviation coined from the initial letter of each successive word in a term or phrase. In general, an acronym made up solely from the first letter of the major words in the expanded form is rendered in all capital letters (NATO from North Atlantic Treaty Organization; an exception would be ASEAN for Association of Southeast Asian Nations). In general, an acronym made up of more than the first letter of the major words in the expanded form is rendered with only an initial capital letter (Comsat from Communications Satellite Corporation; an exception would be NAM from Nonaligned Movement). Hybrid forms are sometimes used to distinguish between initially identical terms (ICC for International Chamber of Commerce and ICCt for International Criminal Court).

Administrative divisions This entry generally gives the numbers, designatory terms, and first-order administrative divisions as approved by the US Board on Geographic Names (BGN). Changes that have been reported but not yet acted on by the BGN are noted. Geographic names conform to spellings approved by the BGN with the exception of the omission of diacritical marks and special characters.

Age structure This entry provides the distribution of the population according to age. Information is included by sex and age group as follows: 0-14 years (children), 15-24 years (early working age), 25-54 years (prime working age), 55-64 years (mature working age), 65 years and over (elderly). The age structure of a population affects a nation's key socioeconomic issues. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest.

Agriculture - products This entry is an ordered listing of major crops and products starting with the most important.

Airports This entry gives the total number of airports or airfields recognizable from the air. The runway(s) may be paved (concrete or asphalt surfaces) or unpaved (grass, earth, sand, or gravel surfaces) and may include closed or abandoned installations. Airports or airfields that are no longer recognizable (overgrown, no facilities, etc.) are not included. Note that not all airports have accommodations for refueling, maintenance, or air traffic control.

Airports - with paved runways This entry gives the total number of airports with paved runways (concrete or asphalt surfaces) by length. For airports with more than one runway, only the longest runway is included according to the following five groups - (1) over 3,047 m (over 10,000 ft), (2) 2,438 to 3,047 m (8,000 to 10,000 ft), (3) 1,524 to 2,437 m (5,000 to 8,000 ft), (4) 914 to 1,523 m (3,000 to 5,000 ft), and (5) under 914 m (under 3,000 ft). Only airports with usable runways are included in this listing. Not all airports have facilities for refueling, maintenance, or air traffic control. The type aircraft capable of operating from a runway of a given length is dependent upon a number of factors including elevation of the runway, runway gradient, average maximum daily temperature at the airport, engine types, flap settings, and take-off weight of the aircraft.

Airports - with unpaved runways This entry gives the total number of airports with unpaved runways (grass, dirt, sand, or gravel surfaces) by length. For airports with more than one runway, only the longest runway is included according to the following five groups - (1) over 3,047 m (over 10,000 ft), (2) 2,438 to 3,047 m (8,000 to 10,000 ft), (3) 1,524 to 2,437 m (5,000 to 8,000 ft), (4) 914 to 1,523 m (3,000 to 5,000 ft), and (5) under 914 m (under 3,000 ft). Only airports with usable runways are included in this listing. Not all airports have facilities for refueling, maintenance, or air traffic control. The type aircraft capable of operating from a runway of a given length is dependent upon a number of factors including elevation of the runway, runway gradient, average maximum daily temperature at the airport, engine types, flap settings, and take-off weight of the aircraft.

Appendixes This section includes Factbook-related material by topic.

Area This entry includes three subfields. Total area is the sum of all land and water areas delimited by international boundaries and/or coastlines. Land area is the aggregate of all surfaces delimited by international boundaries and/or coastlines, excluding inland water bodies (lakes, reservoirs, rivers). Water area is the sum of the surfaces of all inland water bodies, such as lakes, reservoirs, or rivers, as delimited by international boundaries and/or coastlines.

Area - comparative This entry provides an area comparison based on total area equivalents. Most entities are compared with the entire US or one of the 50 states based on area measurements (1990 revised) provided by the US Bureau of the Census. The smaller entities are compared with Washington, DC (178 sq km, 69 sq mi) or The Mall in Washington, DC (0.59 sq km, 0.23 sq mi, 146 acres).

Area - rankings This entry, which appears only in the World, Geography category, provides rankings for the earth's largest (or smallest) continents, countries, oceans, islands, mountain ranges, or other physical features.

Background This entry usually highlights major historic events and current issues and may include a statement about one or two key future trends.

Birth rate This entry gives the average annual number of births during a year per 1,000 persons in the population at midyear; also known as crude birth rate. The birth rate is usually the dominant factor in determining the rate of population growth. It depends on both the level of fertility and the age structure of the population.

Broadband - fixed subscriptions This entry gives the total number of fixed-broadband subscriptions, as well as the number of subscriptions per 100 inhabitants. Fixed broadband is a physical wired connection to the Internet (e.g., coaxial cable, optical fiber) at speeds equal to or greater than 256 kilobits/second (256 kbit/s).

Broadcast media This entry provides information on the approximate number of public and private TV and radio stations in a country, as well as basic information on the availability of satellite and cable TV services.

Budget This entry includes revenues, expenditures, and capital expenditures. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms.

Budget surplus (+) or deficit (-) This entry records the difference between national government revenues and expenditures, expressed as a percent of GDP. A positive (+) number indicates that revenues exceeded expenditures (a budget surplus), while a negative (-) number indicates the reverse (a budget deficit). Normalizing the data, by dividing the budget balance by GDP, enables easy comparisons across countries and indicates whether a national government saves or borrows money. Countries with high budget deficits (relative to their GDPs) generally have more difficulty raising funds to finance expenditures, than those with lower deficits.

Capital This entry gives the name of the seat of government, its geographic coordinates, the time difference relative to Coordinated Universal Time (UTC) and the time observed in Washington, DC, and, if applicable, information on daylight saving time (DST). Where appropriate, a special note has been added to highlight those countries that have multiple time zones.

Carbon dioxide emissions from consumption of energy This entry is the total amount of carbon dioxide, measured in metric tons, released by burning fossil fuels in the process of producing and consuming energy.

Children under the age of 5 years underweight This entry gives the percent of children under five considered to be underweight. Underweight means weight-for-age is approximately 2 kg below for standard at age one, 3 kg below standard for ages two and three, and 4 kg below standard for ages four and five. This statistic is an indicator of the nutritional status of a community. Children who suffer from growth retardation as a result of poor diets and/or recurrent infections tend to have a greater risk of suffering illness and death.

Citizenship This entry provides information related to the acquisition and exercise of citizenship; it includes four subfields:



citizenship by birth describes the acquisition of citizenship based on place of birth, known as Jus soli, regardless of the citizenship of parents.



citizenship by descent only describes the acquisition of citizenship based on the principle of Jus sanguinis, or by descent, where at least one parent is a citizen of the state and being born within the territorial limits of the state is not required. The majority of countries adhere to this practice. In some cases, citizenship is conferred through the father or mother exclusively.



dual citizenship recognized indicates whether a state permits a citizen to simultaneously hold citizenship in another state. Many states do not permit dual citizenship and the voluntary acquisition of citizenship in another country is grounds for revocation of citizenship. Holding dual citizenship makes an individual legally obligated to more than one state and can negate the normal consular protections afforded to citizens outside their original country of citizenship.



residency requirement for naturalization lists the length of time an applicant is required to live in a state before applying for naturalization. In most countries citizenship can be acquired through the legal process of naturalization. The requirements for naturalization vary by state but generally include no criminal record, good health, economic wherewithal, and a period of authorized residency in the state. This time period can vary enormously among states and is often used to make the acquisition of citizenship difficult or impossible.

Civil aircraft registration country code prefix This entry provides the one- or two-character alphanumeric code indicating the nationality of civil aircraft. Article 20 of the Convention on International Civil Aviation (Chicago Convention), signed in 1944, requires that all aircraft engaged in international air navigation bear appropriate nationality marks. The aircraft registration number consists of two parts: a prefix consisting of a one- or two-character alphanumeric code indicating nationality and a registration suffix of one to five characters for the specific aircraft. The prefix codes are based upon radio call-signs allocated by the International Telecommunications Union (ITU) to each country. Since 1947, the International Civil Aviation Organization (ICAO) has managed code standards and their allocation.

Climate



ten driest places on earth (average annual precipitation) describes the annual average precipitation measured in both millimeters and inches for selected countries with climate extremes. This entry includes a brief description of typical weather regimes throughout the year; in the Word entry only, it includes four subfields that describe climate extremes:ten driest places on earth (average annual precipitation) describes the annual average precipitation measured in both millimeters and inches for selected countries with climate extremes. ten wettest places on earth (average annual precipitation) describes the annual average precipitation measured in both millimeters and inches for selected countries with climate extremes. ten coldest places on earth (lowest average monthly temperature) describes temperature measured in both degrees Celsius and Fahrenheit as well as the month of the year for selected countries with climate extremes. ten hottest places on earth (highest average monthly temperature) describes the temperature measured both in degrees Celsius and Fahrenheit as well the month of the year for selected countries with climate extremes.

Coastline This entry gives the total length of the boundary between the land area (including islands) and the sea.

Communications This category deals with the means of exchanging information and includes the telephone, radio, television, and Internet host entries.

Communications - note This entry includes miscellaneous communications information of significance not included elsewhere.

Constitution This entry provides information on a country’s constitution and includes two subfields. The history subfield includes the dates of previous constitutions and the main steps and dates in formulating and implementing the latest constitution. For countries with 1-3 previous constitutions, the years are listed; for those with 4-9 previous, the entry is listed as “several previous,” and for those with 10 or more, the entry is “many previous.” The amendments subfield summarizes the process of amending a country’s constitution – from proposal through passage – and the dates of amendments, which are treated in the same manner as the constitution dates. Where appropriate, summaries are composed from English-language translations of non-English constitutions, which derive from official or non-official translations or machine translators.



The main steps in creating a constitution and amending it usually include the following steps: proposal, drafting, legislative and/or executive branch review and approval, public referendum, and entry into law. In many countries this process is lengthy. Terms commonly used to describe constitutional changes are “amended,” “revised,” or “reformed.” In countries such as South Korea and Turkmenistan, sources differ as to whether changes are stated as new constitutions or are amendments/revisions to existing ones.



A few countries including Canada, Israel, and the UK have no single constitution document, but have various written and unwritten acts, statutes, common laws, and practices that, when taken together, describe a body of fundamental principles or established precedents as to how their countries are governed. Some special regions (Hong Kong, Macau) and countries (Oman, Saudi Arabia) use the term “basic law” instead of constitution.



A number of self-governing dependencies and territories such as the Cayman Islands, Bermuda, and Gibraltar (UK), Greenland and Faroe Islands (Denmark), Aruba, Curacao, and Sint Maarten (Netherlands), and Puerto Rico and the Virgin Islands (US) have their own constitutions.

Contraceptive prevalence rate This field gives the percent of women of reproductive age (15-49) who are married or in union and are using, or whose sexual partner is using, a method of contraception according to the date of the most recent available data. The contraceptive prevalence rate is an indicator of health services, development, and women’s empowerment. It is also useful in understanding, past, present, and future fertility trends, especially in developing countries.

Coordinated Universal Time (UTC) UTC is the international atomic time scale that serves as the basis of timekeeping for most of the world. The hours, minutes, and seconds expressed by UTC represent the time of day at the Prime Meridian (0º longitude) located near Greenwich, England as reckoned from midnight. UTC is calculated by the Bureau International des Poids et Measures (BIPM) in Sevres, France. The BIPM averages data collected from more than 200 atomic time and frequency standards located at about 50 laboratories worldwide. UTC is the basis for all civil time, with the world divided into time zones expressed as positive or negative differences from UTC. UTC is also referred to as "Zulu time." See the Standard Time Zones of the World map included with the Reference Maps.

Country data codes See Data codes.

Country map Most versions of the Factbook provide a country map in color. The maps were produced from the best information available at the time of preparation. Names and/or boundaries may have changed subsequently.

Country name This entry includes all forms of the country's name approved by the US Board on Geographic Names (Italy is used as an example): conventional long form (Italian Republic), conventional short form (Italy), local long form (Repubblica Italiana), local short form (Italia), former (Kingdom of Italy), as well as the abbreviation. Also see the Terminology note.

Crude oil - exports This entry is the total amount of crude oil exported, in barrels per day (bbl/day).

Crude oil - imports This entry is the total amount of crude oil imported, in barrels per day (bbl/day).

Crude oil - production This entry is the total amount of crude oil produced, in barrels per day (bbl/day).

Crude oil - proved reserves This entry is the stock of proved reserves of crude oil, in barrels (bbl). Proved reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated with a high degree of confidence to be commercially recoverable from a given date forward, from known reservoirs and under current economic conditions.

Current account balance This entry records a country's net trade in goods and services, plus net earnings from rents, interest, profits, and dividends, and net transfer payments (such as pension funds and worker remittances) to and from the rest of the world during the period specified. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms.

Current Health Expenditure Current Health Expenditure (CHE) describes the share of spending on health in each country relative to the size of its economy. It includes expenditures corresponding to the final consumption of health care goods and services and excludes investment, exports, and intermediate consumption. CHE shows the importance of the health sector in the economy and indicates the priority given to health in monetary terms. Note: Current Health Expenditure replaces the former Health Expenditures field and is calculated differently.

Date of information In general, information available as of January in a given year is used in the preparation of the printed edition.

Daylight Saving Time (DST) This entry is included for those entities that have adopted a policy of adjusting the official local time forward, usually one hour, from Standard Time during summer months. Such policies are most common in mid-latitude regions.

Death rate This entry gives the average annual number of deaths during a year per 1,000 population at midyear; also known as crude death rate. The death rate, while only a rough indicator of the mortality situation in a country, accurately indicates the current mortality impact on population growth. This indicator is significantly affected by age distribution, and most countries will eventually show a rise in the overall death rate, in spite of continued decline in mortality at all ages, as declining fertility results in an aging population.

Debt - external This entry gives the total public and private debt owed to nonresidents repayable in internationally accepted currencies, goods, or services. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms.

Demographic profile This entry describes a country’s key demographic features and trends and how they vary among regional, ethnic, and socioeconomic sub-populations. Some of the topics addressed are population age structure, fertility, health, mortality, poverty, education, and migration.

Dependency ratios Dependency ratios are a measure of the age structure of a population. They relate the number of individuals that are likely to be economically "dependent" on the support of others. Dependency ratios contrast the ratio of youths (ages 0-14) and the elderly (ages 65+) to the number of those in the working-age group (ages 15-64). Changes in the dependency ratio provide an indication of potential social support requirements resulting from changes in population age structures. As fertility levels decline, the dependency ratio initially falls because the proportion of youths decreases while the proportion of the population of working age increases. As fertility levels continue to decline, dependency ratios eventually increase because the proportion of the population of working age starts to decline and the proportion of elderly persons continues to increase.



total dependency ratio - The total dependency ratio is the ratio of combined youth population (ages 0-14) and elderly population (ages 65+) per 100 people of working age (ages 15-64). A high total dependency ratio indicates that the working-age population and the overall economy face a greater burden to support and provide social services for youth and elderly persons, who are often economically dependent.



youth dependency ratio - The youth dependency ratio is the ratio of the youth population (ages 0-14) per 100 people of working age (ages 15-64). A high youth dependency ratio indicates that a greater investment needs to be made in schooling and other services for children.



elderly dependency ratio - The elderly dependency ratio is the ratio of the elderly population (ages 65+) per 100 people of working age (ages 15-64). Increases in the elderly dependency ratio put added pressure on governments to fund pensions and healthcare.



potential support ratio - The potential support ratio is the number of working-age people (ages 15-64) per one elderly person (ages 65+). As a population ages, the potential support ratio tends to fall, meaning there are fewer potential workers to support the elderly.

Dependency status This entry describes the formal relationship between a particular nonindependent entity and an independent state.

Dependent areas This entry contains an alphabetical listing of all nonindependent entities associated in some way with a particular independent state.

Diplomatic representation The US Government has diplomatic relations with 190 independent states, including 188 of the 193 UN members (excluded UN members are Bhutan, Cuba, Iran, North Korea, and the US itself). In addition, the US has diplomatic relations with 2 independent states that are not in the UN, the Holy See and Kosovo, as well as with the EU.

Diplomatic representation from the US This entry includes the chief of mission, embassy address, mailing address, telephone number, FAX number, branch office locations, consulate general locations, and consulate locations.

Diplomatic representation in the US This entry includes the chief of mission, chancery address, telephone, FAX, consulate general locations, and consulate locations. The use of the annotated title Appointed Ambassador refers to a new ambassador who has presented his/her credentials to the secretary of state but not the US president. Such ambassadors fulfill all diplomatic functions except meeting with or appearing at functions attended by the president until such time as they formally present their credentials at a White House ceremony.

Disputes - international This entry includes a wide variety of situations that range from traditional bilateral boundary disputes to unilateral claims of one sort or another. Information regarding disputes over international terrestrial and maritime boundaries has been reviewed by the US Department of State. References to other situations involving borders or frontiers may also be included, such as resource disputes, geopolitical questions, or irredentist issues; however, inclusion does not necessarily constitute official acceptance or recognition by the US Government.

Drinking water source This entry provides information about access to improved or unimproved drinking water sources available to segments of the population of a country. Improved drinking water - use of any of the following sources: piped water into dwelling, yard, or plot; public tap or standpipe; tubewell or borehole; protected dug well; protected spring; or rainwater collection. Unimproved drinking water - use of any of the following sources: unprotected dug well; unprotected spring; cart with small tank or drum; tanker truck; surface water, which includes rivers, dams, lakes, ponds, streams, canals or irrigation channels; or bottled water.

Economy This category includes the entries dealing with the size, development, and management of productive resources, i.e., land, labor, and capital.

Economy - overview This entry briefly describes the type of economy, including the degree of market orientation, the level of economic development, the most important natural resources, and the unique areas of specialization. It also characterizes major economic events and policy changes in the most recent 12 months and may include a statement about one or two key future macroeconomic trends.

Education expenditures This entry provides the public expenditure on education as a percent of GDP.

Electricity - consumption This entry consists of total electricity generated annually plus imports and minus exports, expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution.

Electricity - exports This entry is the total exported electricity in kilowatt-hours.

Electricity - from fossil fuels This entry measures the capacity of plants that generate electricity by burning fossil fuels (such as coal, petroleum products, and natural gas), expressed as a share of the country's total generating capacity.

Electricity - imports This entry is the total imported electricity in kilowatt-hours.

Electricity - installed generating capacity This entry is the total capacity of currently installed generators, expressed in kilowatts (kW), to produce electricity. A 10-kilowatt (kW) generator will produce 10 kilowatt hours (kWh) of electricity, if it runs continuously for one hour.

Electricity - production This entry is the annual electricity generated expressed in kilowatt-hours. The discrepancy between the amount of electricity generated and/or imported and the amount consumed and/or exported is accounted for as loss in transmission and distribution.

Electricity access This entry provides information on access to electricity. Electrification data – collected from industry reports, national surveys, and international sources – consists of four subfields. Population without electricity provides an estimate of the number of citizens that do not have access to electricity. Electrification – total population is the percent of a country’s total population with access to electricity, electrification – urban areas is the percent of a country’s urban population with access to electricity, while electrification – rural areas is the percent of a country’s rural population with access to electricity. Due to differences in definitions and methodology from different sources, data quality may vary from country to country.

Elevation This entry includes the mean elevation and elevation extremes, lowest point and highest point.

Energy This category includes entries dealing with the production, consumption, import, and export of various forms of energy including electricity, crude oil, refined petroleum products, and natural gas.

Entities Some of the independent states, dependencies, areas of special sovereignty, and governments included in this publication are not independent, and others are not officially recognized by the US Government. "Independent state" refers to a people politically organized into a sovereign state with a definite territory. "Dependencies" and "areas of special sovereignty" refer to a broad category of political entities that are associated in some way with an independent state. "Country" names used in the table of contents or for page headings are usually the short-form names as approved by the US Board on Geographic Names and may include independent states, dependencies, and areas of special sovereignty, or other geographic entities. There are a total of 267 separate geographic entities in The World Factbook that may be categorized as follows:

Environment - current issues This entry lists the most pressing and important environmental problems. The following terms and abbreviations are used throughout the entry:

Acidification - the lowering of soil and water pH due to acid precipitation and deposition usually through precipitation; this process disrupts ecosystem nutrient flows and may kill freshwater fish and plants dependent on more neutral or alkaline conditions (see acid rain).

Acid rain - characterized as containing harmful levels of sulfur dioxide or nitrogen oxide; acid rain is damaging and potentially deadly to the earth's fragile ecosystems; acidity is measured using the pH scale where 7 is neutral, values greater than 7 are considered alkaline, and values below 5.6 are considered acid precipitation; note - a pH of 2.4 (the acidity of vinegar) has been measured in rainfall in New England.

Aerosol - a collection of airborne particles dispersed in a gas, smoke, or fog.

Afforestation - converting a bare or agricultural space by planting trees and plants; reforestation involves replanting trees on areas that have been cut or destroyed by fire.

Asbestos - a naturally occurring soft fibrous mineral commonly used in fireproofing materials and considered to be highly carcinogenic in particulate form.

Biodiversity - also biological diversity; the relative number of species, diverse in form and function, at the genetic, organism, community, and ecosystem level; loss of biodiversity reduces an ecosystem's ability to recover from natural or man-induced disruption.

Bio-indicators - a plant or animal species whose presence, abundance, and health reveal the general condition of its habitat.

Biomass - the total weight or volume of living matter in a given area or volume.

Carbon cycle - the term used to describe the exchange of carbon (in various forms, e.g., as carbon dioxide) between the atmosphere, ocean, terrestrial biosphere, and geological deposits.

Catchments - assemblages used to capture and retain rainwater and runoff; an important water management technique in areas with limited freshwater resources, such as Gibraltar.

DDT (dichloro-diphenyl-trichloro-ethane) - a colorless, odorless insecticide that has toxic effects on most animals; the use of DDT was banned in the US in 1972.

Defoliants - chemicals which cause plants to lose their leaves artificially; often used in agricultural practices for weed control, and may have detrimental impacts on human and ecosystem health.

Deforestation - the destruction of vast areas of forest (e.g., unsustainable forestry practices, agricultural and range land clearing, and the over exploitation of wood products for use as fuel) without planting new growth.

Desertification - the spread of desert-like conditions in arid or semi-arid areas, due to overgrazing, loss of agriculturally productive soils, or climate change.

Dredging - the practice of deepening an existing waterway; also, a technique used for collecting bottom-dwelling marine organisms (e.g., shellfish) or harvesting coral, often causing significant destruction of reef and ocean-floor ecosystems.

Drift-net fishing - done with a net, miles in extent, that is generally anchored to a boat and left to float with the tide; often results in an over harvesting and waste of large populations of non-commercial marine species (by-catch) by its effect of"sweeping the ocean clean."

Ecosystems - ecological units comprised of complex communities of organisms and their specific environments.

Effluents - waste materials, such as smoke, sewage, or industrial waste which are released into the environment, subsequently polluting it.

Endangered species - a species that is threatened with extinction either by direct hunting or habitat destruction.

Freshwater - water with very low soluble mineral content; sources include lakes, streams, rivers, glaciers, and underground aquifers.

Greenhouse gas - a gas that"traps" infrared radiation in the lower atmosphere causing surface warming; water vapor, carbon dioxide, nitrous oxide, methane, hydrofluorocarbons, and ozone are the primary greenhouse gases in the Earth's atmosphere.

Groundwater - water sources found below the surface of the earth often in naturally occurring reservoirs in permeable rock strata; the source for wells and natural springs.

Highlands Water Project - a series of dams constructed jointly by Lesotho and South Africa to redirect Lesotho's abundant water supply into a rapidly growing area in South Africa; while it is the largest infrastructure project in southern Africa, it is also the most costly and controversial; objections to the project include claims that it forces people from their homes, submerges farmlands, and squanders economic resources.

Inuit Circumpolar Conference (ICC) - represents the roughly 150,000 Inuits of Alaska, Canada, Greenland, and Russia in international environmental issues; a General Assembly convenes every three years to determine the focus of the ICC; the most current concerns are long-range transport of pollutants, sustainable development, and climate change.

Metallurgical plants - industries which specialize in the science, technology, and processing of metals; these plants produce highly concentrated and toxic wastes which can contribute to pollution of ground water and air when not properly disposed.

Noxious substances - injurious, very harmful to living beings.

Overgrazing - the grazing of animals on plant material faster than it can naturally regrow leading to the permanent loss of plant cover, a common effect of too many animals grazing limited range land.

Ozone shield - a layer of the atmosphere composed of ozone gas (O3) that resides approximately 25 miles above the Earth's surface and absorbs solar ultraviolet radiation that can be harmful to living organisms.

Poaching - the illegal killing of animals or fish, a great concern with respect to endangered or threatened species.

Pollution - the contamination of a healthy environment by man-made waste.

Potable water - water that is drinkable, safe to be consumed.

Salination - the process through which fresh (drinkable) water becomes salt (undrinkable) water; hence, desalination is the reverse process; also involves the accumulation of salts in topsoil caused by evaporation of excessive irrigation water, a process that can eventually render soil incapable of supporting crops.

Siltation - occurs when water channels and reservoirs become clotted with silt and mud, a side effect of deforestation and soil erosion.

Slash-and-burn agriculture - a rotating cultivation technique in which trees are cut down and burned in order to clear land for temporary agriculture; the land is used until its productivity declines at which point a new plot is selected and the process repeats; this practice is sustainable while population levels are low and time is permitted for regrowth of natural vegetation; conversely, where these conditions do not exist, the practice can have disastrous consequences for the environment.

Soil degradation - damage to the land's productive capacity because of poor agricultural practices such as the excessive use of pesticides or fertilizers, soil compaction from heavy equipment, or erosion of topsoil, eventually resulting in reduced ability to produce agricultural products.

Soil erosion - the removal of soil by the action of water or wind, compounded by poor agricultural practices, deforestation, overgrazing, and desertification.

Ultraviolet (UV) radiation - a portion of the electromagnetic energy emitted by the sun and naturally filtered in the upper atmosphere by the ozone layer; UV radiation can be harmful to living organisms and has been linked to increasing rates of skin cancer in humans.

Waterborne diseases - those in which bacteria survive in, and are transmitted through, water; always a serious threat in areas with an untreated water supply.

Environment - international agreements This entry separates country participation in international environmental agreements into two levels - party to and signed, but not ratified. Agreements are listed in alphabetical order by the abbreviated form of the full name.

Environmental agreements This information is presented in Appendix C: Selected International Environmental Agreements , which includes the name, abbreviation, date opened for signature, date entered into force, objective, and parties by category.

Ethnic groups This entry provides an ordered listing of ethnic groups starting with the largest and normally includes the percent of total population.

Exchange rates This entry provides the average annual price of a country's monetary unit for the time period specified, expressed in units of local currency per US dollar, as determined by international market forces or by official fiat. The International Organization for Standardization (ISO) 4217 alphabetic currency code for the national medium of exchange is presented in parenthesis. Closing daily exchange rates are not presented in The World Factbook, but are used to convert stock values - e.g., the market value of publicly traded shares - to US dollars as of the specified date.

Executive branch This entry includes five subentries: chief of state; head of government; cabinet; elections/appointments; election results. Chief of state includes the name, title, and beginning date in office of the titular leader of the country who represents the state at official and ceremonial functions but may not be involved with the day-to-day activities of the government. Head of government includes the name, title of the top executive designated to manage the executive branch of the government, and the beginning date in office. Cabinet includes the official name of the executive branch’s high-ranking body and the method of member selection. Elections/appointments includes the process for accession to office, date of the last election, and date of the next election. Election results includes each candidate's political affiliation, percent of direct popular vote or indirect legislative/parliamentary percent vote or vote count in the last election.



The executive branches in approximately 80% of the world's countries have separate chiefs of state and heads of government; for the remainder, the chief of state is also the head of government, such as in Argentina, Kenya, the Philippines, the US, and Venezuela. Chiefs of state in just over 100 countries are directly elected, most by majority popular vote; those in another 55 are indirectly elected by their national legislatures, parliaments, or electoral colleges. Another 29 countries have a monarch as the chief of state. In dependencies, territories, and collectivities of sovereign countries - except those of the US - representatives are appointed to serve as chiefs of state.



Heads of government in the majority of countries are appointed either by the president or the monarch or selected by the majority party in the legislative body. Excluding countries where the chief of state is also head of government, in only a few countries is the head of government directly elected through popular vote.



Most of the world's countries have cabinets, the majority of which are appointed by the chief of state or prime minister, many in consultation with each other or with the legislature. Cabinets in only about a dozen countries are elected solely by their legislative bodies.

Exports This entry provides the total US dollar amount of merchandise exports on an f.o.b. (free on board) basis. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms.

Exports - commodities This entry provides a listing of the highest-valued exported products; it sometimes includes the percent of total dollar value.

Exports - partners This entry provides a rank ordering of trading partners starting with the most important; it sometimes includes the percent of total dollar value.

Fiscal year This entry identifies the beginning and ending months for a country's accounting period of 12 months, which often is the calendar year but which may begin in any month. All yearly references are for the calendar year (CY) unless indicated as a noncalendar fiscal year (FY).

Flag description This entry provides a written flag description produced from actual flags or the best information available at the time the entry was written. The flags of independent states are used by their dependencies unless there is an officially recognized local flag. Some disputed and other areas do not have flags.

Flag graphic Most versions of the Factbook include a color flag at the beginning of the country profile. The flag graphics were produced from actual flags or the best information available at the time of preparation. The flags of independent states are used by their dependencies unless there is an officially recognized local flag. Some disputed and other areas do not have flags.

GDP (official exchange rate) This entry gives the gross domestic product (GDP) or value of all final goods and services produced within a nation in a given year. A nation's GDP at official exchange rates (OER) is the home-currency-denominated annual GDP figure divided by the bilateral average US exchange rate with that country in that year. The measure is simple to compute and gives a precise measure of the value of output. Many economists prefer this measure when gauging the economic power an economy maintains vis-à-vis its neighbors, judging that an exchange rate captures the purchasing power a nation enjoys in the international marketplace. Official exchange rates, however, can be artificially fixed and/or subject to manipulation - resulting in claims of the country having an under- or over-valued currency - and are not necessarily the equivalent of a market-determined exchange rate. Moreover, even if the official exchange rate is market-determined, market exchange rates are frequently established by a relatively small set of goods and services (the ones the country trades) and may not capture the value of the larger set of goods the country produces. Furthermore, OER-converted GDP is not well suited to comparing domestic GDP over time, since appreciation/depreciation from one year to the next will make the OER GDP value rise/fall regardless of whether home-currency-denominated GDP changed.

GDP (purchasing power parity) This entry gives the gross domestic product (GDP) or value of all final goods and services produced within a nation in a given year. A nation's GDP at purchasing power parity (PPP) exchange rates is the sum value of all goods and services produced in the country valued at prices prevailing in the United States in the year noted. This is the measure most economists prefer when looking at per-capita welfare and when comparing living conditions or use of resources across countries. The measure is difficult to compute, as a US dollar value has to be assigned to all goods and services in the country regardless of whether these goods and services have a direct equivalent in the United States (for example, the value of an ox-cart or non-US military equipment); as a result, PPP estimates for some countries are based on a small and sometimes different set of goods and services. In addition, many countries do not formally participate in the World Bank's PPP project that calculates these measures, so the resulting GDP estimates for these countries may lack precision. For many developing countries, PPP-based GDP measures are multiples of the official exchange rate (OER) measure. The differences between the OER- and PPP-denominated GDP values for most of the wealthy industrialized countries are generally much smaller.

GDP - composition, by end use This entry shows who does the spending in an economy: consumers, businesses, government, and foreigners. The distribution gives the percentage contribution to total GDP of household consumption, government consumption, investment in fixed capital, investment in inventories, exports of goods and services, and imports of goods and services, and will total 100 percent of GDP if the data are complete.



household consumption consists of expenditures by resident households, and by nonprofit institutions that serve households, on goods and services that are consumed by individuals. This includes consumption of both domestically produced and foreign goods and services.



government consumption consists of government expenditures on goods and services. These figures exclude government transfer payments, such as interest on debt, unemployment, and social security, since such payments are not made in exchange for goods and services supplied.



investment in fixed capital consists of total business spending on fixed assets, such as factories, machinery, equipment, dwellings, and inventories of raw materials, which provide the basis for future production. It is measured gross of the depreciation of the assets, i.e., it includes investment that merely replaces worn-out or scrapped capital. Earlier editions of The World Factbook referred to this concept as Investment (gross fixed) and that data now have been moved to this new field.



investment in inventories consists of net changes to the stock of outputs that are still held by the units that produce them, awaiting further sale to an end user, such as automobiles sitting on a dealer’s lot or groceries on the store shelves. This figure may be positive or negative. If the stock of unsold output increases during the relevant time period, investment in inventories is positive, but, if the stock of unsold goods declines, it will be negative. Investment in inventories normally is an early indicator of the state of the economy. If the stock of unsold items increases unexpectedly – because people stop buying - the economy may be entering a recession; but if the stock of unsold items falls - and goods "go flying off the shelves" - businesses normally try to replace those stocks, and the economy is likely to accelerate.



exports of goods and services consist of sales, barter, gifts, or grants of goods and services from residents to nonresidents.



imports of goods and services consist of purchases, barter, or receipts of gifts, or grants of goods and services by residents from nonresidents. Exports are treated as a positive item, while imports are treated as a negative item. In a purely accounting sense, imports have no direct impact on GDP, which only measures output of the domestic economy. Imports are entered as a negative item to offset the fact that the expenditure figures for consumption, investment, government, and exports also include expenditures on imports. These imports contribute directly to foreign GDP but only indirectly to domestic GDP. Because of this negative offset for imports of goods and services, the sum of the other five items, excluding imports, will always total more than 100 percent of GDP. A surplus of exports of goods and services over imports indicates an economy is investing abroad, while a deficit indicates an economy is borrowing from abroad.

GDP - composition, by sector of origin This entry shows where production takes place in an economy. The distribution gives the percentage contribution of agriculture, industry, and services to total GDP, and will total 100 percent of GDP if the data are complete. Agriculture includes farming, fishing, and forestry. Industry includes mining, manufacturing, energy production, and construction. Services cover government activities, communications, transportation, finance, and all other private economic activities that do not produce material goods.

GDP - per capita (PPP) This entry shows GDP on a purchasing power parity basis divided by population as of 1 July for the same year.

GDP - real growth rate This entry gives GDP growth on an annual basis adjusted for inflation and expressed as a percent. The growth rates are year-over-year, and not compounded.

GDP methodology In the Economy category, GDP dollar estimates for countries are reported both on an official exchange rate (OER) and a purchasing power parity (PPP) basis. Both measures contain information that is useful to the reader. The PPP method involves the use of standardized international dollar price weights, which are applied to the quantities of final goods and services produced in a given economy. The data derived from the PPP method probably provide the best available starting point for comparisons of economic strength and well-being between countries. In contrast, the currency exchange rate method involves a variety of international and domestic financial forces that may not capture the value of domestic output. Whereas PPP estimates for OECD countries are quite reliable, PPP estimates for developing countries are often rough approximations. In developing countries with weak currencies, the exchange rate estimate of GDP in dollars is typically one-fourth to one-half the PPP estimate. Most of the GDP estimates for developing countries are based on extrapolation of PPP numbers published by the UN International Comparison Program (UNICP) and by Professors Robert Summers and Alan Heston of the University of Pennsylvania and their colleagues. GDP derived using the OER method should be used for the purpose of calculating the share of items such as exports, imports, military expenditures, external debt, or the current account balance, because the dollar values presented in the Factbook for these items have been converted at official exchange rates, not at PPP. One should use the OER GDP figure to calculate the proportion of, say, Chinese defense expenditures in GDP, because that share will be the same as one calculated in local currency units. Comparison of OER GDP with PPP GDP may also indicate whether a currency is over- or under-valued. If OER GDP is smaller than PPP GDP, the official exchange rate may be undervalued, and vice versa. However, there is no strong historical evidence that market exchange rates move in the direction implied by the PPP rate, at least not in the short- or medium-term. Note: the numbers for GDP and other economic data should not be chained together from successive volumes of the Factbook because of changes in the US dollar measuring rod, revisions of data by statistical agencies, use of new or different sources of information, and changes in national statistical methods and practices.

Geographic coordinates This entry includes rounded latitude and longitude figures for the centroid or center point of a country expressed in degrees and minutes; it is based on the locations provided in the Geographic Names Server (GNS), maintained by the National Geospatial-Intelligence Agency on behalf of the US Board on Geographic Names.

Geographic names This information is presented in Appendix F: Cross Reference List of Geographic Names . It includes a listing of various alternate names, former names, local names, and regional names referenced to one or more related Factbook entries. Spellings are normally, but not always, those approved by the US Board on Geographic Names (BGN). Alternate names and additional information are included in parentheses.

Geographic overview This entry, which appears only in the World, Geography category, provides basic geographic information about the earth's oceans and continents. The entry also lists all of the countries that compose each continent.

Geography This category includes the entries dealing with the natural environment and the effects of human activity.

Geography - note This entry includes miscellaneous geographic information of significance not included elsewhere.

Gini index See entry for Distribution of family income - Gini index

GNP Gross national product (GNP) is the value of all final goods and services produced within a nation in a given year, plus income earned by its citizens abroad, minus income earned by foreigners from domestic production. The Factbook, following current practice, uses GDP rather than GNP to measure national production. However, the user must realize that in certain countries net remittances from citizens working abroad may be important to national well-being.

Government This category includes the entries dealing with the system for the adoption and administration of public policy.

Government - note This entry includes miscellaneous government information of significance not included elsewhere.

Government type This entry gives the basic form of government. Definitions of the major governmental terms are as follows. (Note that for some countries more than one definition applies.):

Absolute monarchy - a form of government where the monarch rules unhindered, i.e., without any laws, constitution, or legally organized opposition.

Anarchy - a condition of lawlessness or political disorder brought about by the absence of governmental authority.

Authoritarian - a form of government in which state authority is imposed onto many aspects of citizens' lives.

Commonwealth - a nation, state, or other political entity founded on law and united by a compact of the people for the common good.

Communist - a system of government in which the state plans and controls the economy and a single - often authoritarian - party holds power; state controls are imposed with the elimination of private ownership of property or capital while claiming to make progress toward a higher social order in which all goods are equally shared by the people (i.e., a classless society).

Confederacy (Confederation) - a union by compact or treaty between states, provinces, or territories, that creates a central government with limited powers; the constituent entities retain supreme authority over all matters except those delegated to the central government.

Constitutional - a government by or operating under an authoritative document (constitution) that sets forth the system of fundamental laws and principles that determines the nature, functions, and limits of that government.

Constitutional democracy - a form of government in which the sovereign power of the people is spelled out in a governing constitution.

Constitutional monarchy - a system of government in which a monarch is guided by a constitution whereby his/her rights, duties, and responsibilities are spelled out in written law or by custom.

Democracy - a form of government in which the supreme power is retained by the people, but which is usually exercised indirectly through a system of representation and delegated authority periodically renewed.

Democratic republic - a state in which the supreme power rests in the body of citizens entitled to vote for officers and representatives responsible to them.

Dictatorship - a form of government in which a ruler or small clique wield absolute power (not restricted by a constitution or laws).

Ecclesiastical - a government administrated by a church.

Emirate - similar to a monarchy or sultanate, but a government in which the supreme power is in the hands of an emir (the ruler of a Muslim state); the emir may be an absolute overlord or a sovereign with constitutionally limited authority.

Federal (Federation) - a form of government in which sovereign power is formally divided - usually by means of a constitution - between a central authority and a number of constituent regions (states, colonies, or provinces) so that each region retains some management of its internal affairs; differs from a confederacy in that the central government exerts influence directly upon both individuals as well as upon the regional units.

Federal republic - a state in which the powers of the central government are restricted and in which the component parts (states, colonies, or provinces) retain a degree of self-government; ultimate sovereign power rests with the voters who chose their governmental representatives.

Islamic republic - a particular form of government adopted by some Muslim states; although such a state is, in theory, a theocracy, it remains a republic, but its laws are required to be compatible with the laws of Islam.

Maoism - the theory and practice of Marxism-Leninism developed in China by Mao Zedong (Mao Tse-tung), which states that a continuous revolution is necessary if the leaders of a communist state are to keep in touch with the people.

Marxism - the political, economic, and social principles espoused by 19th century economist Karl Marx; he viewed the struggle of workers as a progression of historical forces that would proceed from a class struggle of the proletariat (workers) exploited by capitalists (business owners), to a socialist"dictatorship of the proletariat," to, finally, a classless society - Communism.

Marxism-Leninism - an expanded form of communism developed by Lenin from doctrines of Karl Marx; Lenin saw imperialism as the final stage of capitalism and shifted the focus of workers' struggle from developed to underdeveloped countries.

Monarchy - a government in which the supreme power is lodged in the hands of a monarch who reigns over a state or territory, usually for life and by hereditary right; the monarch may be either a sole absolute ruler or a sovereign - such as a king, queen, or prince - with constitutionally limited authority.

Oligarchy - a government in which control is exercised by a small group of individuals whose authority generally is based on wealth or power.

Parliamentary democracy - a political system in which the legislature (parliament) selects the government - a prime minister, premier, or chancellor along with the cabinet ministers - according to party strength as expressed in elections; by this system, the government acquires a dual responsibility: to the people as well as to the parliament.

Parliamentary government (Cabinet-Parliamentary government) - a government in which members of an executive branch (the cabinet and its leader - a prime minister, premier, or chancellor) are nominated to their positions by a legislature or parliament, and are directly responsible to it; this type of government can be dissolved at will by the parliament (legislature) by means of a no confidence vote or the leader of the cabinet may dissolve the parliament if it can no longer function.

Parliamentary monarchy - a state headed by a monarch who is not actively involved in policy formation or implementation (i.e., the exercise of sovereign powers by a monarch in a ceremonial capacity); true governmental leadership is carried out by a cabinet and its head - a prime minister, premier, or chancellor - who are drawn from a legislature (parliament).

Presidential - a system of government where the executive branch exists separately from a legislature (to which it is generally not accountable).

Republic - a representative democracy in which the people's elected deputies (representatives), not the people themselves, vote on legislation.

Socialism - a government in which the means of planning, producing, and distributing goods is controlled by a central government that theoretically seeks a more just and equitable distribution of property and labor; in actuality, most socialist governments have ended up being no more than dictatorships over workers by a ruling elite.

Sultanate - similar to a monarchy, but a government in which the supreme power is in the hands of a sultan (the head of a Muslim state); the sultan may be an absolute ruler or a sovereign with constitutionally limited authority.

Theocracy - a form of government in which a Deity is recognized as the supreme civil ruler, but the Deity's laws are interpreted by ecclesiastical authorities (bishops, mullahs, etc.); a government subject to religious authority.

Totalitarian - a government that seeks to subordinate the individual to the state by controlling not only all political and economic matters, but also the attitudes, values, and beliefs of its population.

Greenwich Mean Time (GMT) The mean solar time at the Greenwich Meridian, Greenwich, England, with the hours and days, since 1925, reckoned from midnight. GMT is now a historical term having been replaced by UTC on 1 January 1972. See Coordinated Universal Time.

Gross domestic product See GDP

Gross national product See GNP

Gross national saving Gross national saving is derived by deducting final consumption expenditure (household plus government) from Gross national disposable income, and consists of personal saving, plus business saving (the sum of the capital consumption allowance and retained business profits), plus government saving (the excess of tax revenues over expenditures), but excludes foreign saving (the excess of imports of goods and services over exports). The figures are presented as a percent of GDP. A negative number indicates that the economy as a whole is spending more income than it produces, thus drawing down national wealth (dissaving).

Gross world product See GWP

GWP This entry gives the gross world product (GWP) or aggregate value of all final goods and services produced worldwide in a given year.

Heliports This entry gives the total number of heliports with hard-surface runways, helipads, or landing areas that support routine sustained helicopter operations exclusively and have support facilities including one or more of the following facilities: lighting, fuel, passenger handling, or maintenance. It includes former airports used exclusively for helicopter operations but excludes heliports limited to day operations and natural clearings that could support helicopter landings and takeoffs.

HIV/AIDS - adult prevalence rate This entry gives an estimate of the percentage of adults (aged 15-49) living with HIV/AIDS. The adult prevalence rate is calculated by dividing the estimated number of adults living with HIV/AIDS at yearend by the total adult population at yearend.

HIV/AIDS - deaths This entry gives an estimate of the number of adults and children who died of AIDS during a given calendar year.

HIV/AIDS - people living with HIV/AIDS This entry gives an estimate of all people (adults and children) alive at yearend with HIV infection, whether or not they have developed symptoms of AIDS.

Hospital bed density This entry provides the number of hospital beds per 1,000 people; it serves as a general measure of inpatient service availability. Hospital beds include inpatient beds available in public, private, general, and specialized hospitals and rehabilitation centers. In most cases, beds for both acute and chronic care are included. Because the level of inpatient services required for individual countries depends on several factors - such as demographic issues and the burden of disease - there is no global target for the number of hospital beds per country. So, while 2 beds per 1,000 in one country may be sufficient, 2 beds per 1,000 in another may be woefully inadequate because of the number of people hospitalized by disease.

Household income or consumption by percentage share Data on household income or consumption come from household surveys, the results adjusted for household size. Nations use different standards and procedures in collecting and adjusting the data. Surveys based on income will normally show a more unequal distribution than surveys based on consumption. The quality of surveys is improving with time, yet caution is still necessary in making inter-country comparisons.

Hydrographic data codes See Data codes

Illicit drugs This entry gives information on the five categories of illicit drugs - narcotics, stimulants, depressants (sedatives), hallucinogens, and cannabis. These categories include many drugs legally produced and prescribed by doctors as well as those illegally produced and sold outside of medical channels.

Cannabis (Cannabis sativa) is the common hemp plant, which provides hallucinogens with some sedative properties, and includes marijuana (pot, Acapulco gold, grass, reefer), tetrahydrocannabinol (THC, Marinol), hashish (hash), and hashish oil (hash oil).

Coca (mostly Erythroxylum coca) is a bush with leaves that contain the stimulant used to make cocaine. Coca is not to be confused with cocoa, which comes from cacao seeds and is used in making chocolate, cocoa, and cocoa butter.

Cocaine is a stimulant derived from the leaves of the coca bush.

Depressants (sedatives) are drugs that reduce tension and anxiety and include chloral hydrate, barbiturates (Amytal, Nembutal, Seconal, phenobarbital), benzodiazepines (Librium, Valium), methaqualone (Quaalude), glutethimide (Doriden), and others (Equanil, Placidyl, Valmid).

Drugs are any chemical substances that effect a physical, mental, emotional, or behavioral change in an individual.

Drug abuse is the use of any licit or illicit chemical substance that results in physical, mental, emotional, or behavioral impairment in an individual.

Hallucinogens are drugs that affect sensation, thinking, self-awareness, and emotion. Hallucinogens include LSD (acid, microdot), mescaline and peyote (mexc, buttons, cactus), amphetamine variants (PMA, STP, DOB), phencyclidine (PCP, angel dust, hog), phencyclidine analogues (PCE, PCPy, TCP), and others (psilocybin, psilocyn).

Hashish is the resinous exudate of the cannabis or hemp plant (Cannabis sativa).

Heroin is a semisynthetic derivative of morphine.

Mandrax is a trade name for methaqualone, a pharmaceutical depressant.

Marijuana is the dried leaf of the cannabis or hemp plant (Cannabis sativa).

Methaqualone is a pharmaceutical depressant, referred to as mandrax in Southwest Asia and Africa.

Narcotics are drugs that relieve pain, often induce sleep, and refer to opium, opium derivatives, and synthetic substitutes. Natural narcotics include opium (paregoric, parepectolin), morphine (MS-Contin, Roxanol), codeine (Tylenol with codeine, Empirin with codeine, Robitussin AC), and thebaine. Semisynthetic narcotics include heroin (horse, smack), and hydromorphone (Dilaudid). Synthetic narcotics include meperidine or Pethidine (Demerol, Mepergan), methadone (Dolophine, Methadose), and others (Darvon, Lomotil).

Opium is the brown, gummy exudate of the incised, unripe seedpod of the opium poppy.

Opium poppy (Papaver somniferum) is the source for the natural and semisynthetic narcotics.

Poppy straw is the entire cut and dried opium poppy-plant material, other than the seeds. Opium is extracted from poppy straw in commercial operations that produce the drug for medical use.

Qat (kat, khat) is a stimulant from the buds or leaves of Catha edulis that is chewed or drunk as tea.

Quaaludes is the North American slang term for methaqualone, a pharmaceutical depressant.

Stimulants are drugs that relieve mild depression, increase energy and activity, and include cocaine (coke, snow, crack), amphetamines (Desoxyn, Dexedrine), ephedrine, ecstasy (clarity, essence, doctor, Adam), phenmetrazine (Preludin), methylphenidate (Ritalin), and others (Cylert, Sanorex, Tenuate).

Imports This entry provides the total US dollar amount of merchandise imports on a c.i.f. (cost, insurance, and freight) or f.o.b. (free on board) basis. These figures are calculated on an exchange rate basis, i.e., not in purchasing power parity (PPP) terms.

Imports - commodities This entry provides a listing of the highest-valued imported products; it sometimes includes the percent of total dollar value.

Imports - partners This entry provides a rank ordering of trading partners starting with the most important; it sometimes includes the percent of total dollar value.

Independence For most countries, this entry gives the date that sovereignty was achieved and from which nation, empire, or trusteeship. For the other countries, the date given may not represent "independence" in the strict sense, but rather some significant nationhood event such as the traditional founding date or the date of unification, federation, confederation, establishment, fundamental change in the form of government, or state succession. For a number of countries, the establishment of statehood was a lengthy evolutionary process occurring over decades or even centuries. In such cases, several significant dates are cited. Dependent areas include the notation "none" followed by the nature of their dependency status. Also see the Terminology note.

Industrial production growth rate This entry gives the annual percentage increase in industrial production (includes manufacturing, mining, and construction).

Industries This entry provides a rank ordering of industries starting with the largest by value of annual output.

Infant mortality rate This entry gives the number of deaths of infants under one year old in a given year per 1,000 live births in the same year. This rate is often used as an indicator of the level of health in a country.

Inflation rate (consumer prices) This entry furnishes the annual percent change in consumer prices compared with the previous year's consumer prices.

International disputes see Disputes - international

International law organization participation This entry includes information on a country's acceptance of jurisdiction of the International Court of Justice (ICJ) and of the International Criminal Court (ICCt); 59 countries have accepted ICJ jurisdiction with reservations and 11 have accepted ICJ jurisdiction without reservations; 122 countries have accepted ICCt jurisdiction. Appendix B: International Organizations and Groups explains the differing mandates of the ICJ and ICCt.

International organization participation This entry lists in alphabetical order by abbreviation those international organizations in which the subject country is a member or participates in some other way.

International organizations This information is presented in Appendix B: International Organizations and Groups which includes the name, abbreviation, date established, aim, and members by category.

Internet country code This entry includes the two-letter codes maintained by the International Organization for Standardization (ISO) in the ISO 3166 Alpha-2 list and used by the Internet Assigned Numbers Authority (IANA) to establish country-coded top-level domains (ccTLDs).

Internet users This entry gives the total number of individuals within a country who can access the Internet at home, via any device type (computer or mobile) and connection. The percent of population with Internet access (i.e., the penetration rate) helps gauge how widespread Internet use is within a country. Statistics vary from country to country and may include users who access the Internet at least several times a week to those who access it only once within a period of several months.

Introduction This category includes one entry, Background.

Investment (gross fixed) This entry records total business spending on fixed assets, such as factories, machinery, equipment, dwellings, and inventories of raw materials, which provide the basis for future production. It is measured gross of the depreciation of the assets, i.e., it includes investment that merely replaces worn-out or scrapped capital.

Irrigated land This entry gives the number of square kilometers of land area that is artificially supplied with water.

Judicial branch This entry includes three subfields. The highest court(s) subfield includes the name(s) of a country's highest level court(s), the number and titles of the judges, and the types of cases heard by the court, which commonly are based on civil, criminal, administrative, and constitutional law. A number of countries have separate constitutional courts. The judge selection and term of office subfield includes the organizations and associated officials responsible for nominating and appointing judges, and a brief description of the process. The selection process can be indicative of the independence of a country's court system from other branches of its government. Also included in this subfield are judges' tenures, which can range from a few years, to a specified retirement age, to lifelong appointments. The subordinate courts subfield lists the courts lower in the hierarchy of a country's court system. A few countries with federal-style governments, such as Brazil, Canada, and the US, in addition to their federal court, have separate state- or province-level court systems, though generally the two systems interact.

Labor force This entry contains the total labor force figure.

Labor force - by occupation This entry lists the percentage distribution of the labor force by sector of occupation. Agriculture includes farming, fishing, and forestry. Industry includes mining, manufacturing, energy production, and construction. Services cover government activities, communications, transportation, finance, and all other economic activities that do not produce material goods. The distribution will total less than 100 percent if the data are incomplete and may range from 99-101 percent due to rounding.

Land boundaries This entry contains the total length of all land boundaries and the individual lengths for each of the contiguous border countries. When available, official lengths published by national statistical agencies are used. Because surveying methods may differ, country border lengths reported by contiguous countries may differ.

Land use This entry contains the percentage shares of total land area for three different types of land use: agricultural land, forest, and other; agricultural land is further divided into arable land - land cultivated for crops like wheat, maize, and rice that are replanted after each harvest, permanent crops - land cultivated for crops like citrus, coffee, and rubber that are not replanted after each harvest, and includes land under flowering shrubs, fruit trees, nut trees, and vines, and permanent pastures and meadows – land used for at least five years or more to grow herbaceous forage, either cultivated or growing naturally; forest area is land spanning more than 0.5 hectare with trees higher than five meters and a canopy cover of more than 10% to include windbreaks, shelterbelts, and corridors of trees greater than 0.5 hectare and at least 20 m wide; land classified as other includes built-up areas, roads and other transportation features, barren land, or wasteland.

Languages This entry provides a listing of languages spoken in each country and specifies any that are official national or regional languages. When data is available, the languages spoken in each country are broken down according to the percent of the total population speaking each language as a first language. For those countries without available data, languages are listed in rank order based on prevalence, starting with the most-spoken language.

Legal system This entry provides the description of a country's legal system. A statement on judicial review of legislative acts is also included for a number of countries. The legal systems of nearly all countries are generally modeled upon elements of five main types: civil law (including French law, the Napoleonic Code, Roman law, Roman-Dutch law, and Spanish law); common law (including United State law); customary law; mixed or pluralistic law; and religious law (including Islamic law). An additional type of legal system - international law, which governs the conduct of independent nations in their relationships with one another - is also addressed below. The following list describes these legal systems, the countries or world regions where these systems are enforced, and a brief statement on the origins and major features of each.

Civil Law - The most widespread type of legal system in the world, applied in various forms in approximately 150 countries. Also referred to as European continental law, the civil law system is derived mainly from the Roman Corpus Juris Civilus, (Body of Civil Law), a collection of laws and legal interpretations compiled under the East Roman (Byzantine) Emperor Justinian I between A.D. 528 and 565. The major feature of civil law systems is that the laws are organized into systematic written codes. In civil law the sources recognized as authoritative are principally legislation - especially codifications in constitutions or statutes enacted by governments - and secondarily, custom. The civil law systems in some countries are based on more than one code.

Common Law - A type of legal system, often synonymous with"English common law," which is the system of England and Wales in the UK, and is also in force in approximately 80 countries formerly part of or influenced by the former British Empire. English common law reflects Biblical influences as well as remnants of law systems imposed by early conquerors including the Romans, Anglo-Saxons, and Normans. Some legal scholars attribute the formation of the English common law system to King Henry II (r.1154-1189). Until the time of his reign, laws customary among England's various manorial and ecclesiastical (church) jurisdictions were administered locally. Henry II established the king's court and designated that laws were "common" to the entire English realm. The foundation of English common law is "legal precedent" - referred to as stare decisis, meaning "to stand by things decided." In the English common law system, court judges are bound in their decisions in large part by the rules and other doctrines developed - and supplemented over time - by the judges of earlier English courts.

Customary Law - A type of legal system that serves as the basis of, or has influenced, the present-day laws in approximately 40 countries - mostly in Africa, but some in the Pacific islands, Europe, and the Near East. Customary law is also referred to as"primitive law," "unwritten law," "indigenous law," and "folk law." There is no single history of customary law such as that found in Roman civil law, English common law, Islamic law, or the Napoleonic Civil Code. The earliest systems of law in human society were customary, and usually developed in small agrarian and hunter-gatherer communities. As the term implies, customary law is based upon the customs of a community. Common attributes of customary legal systems are that they are seldom written down, they embody an organized set of rules regulating social relations, and they are agreed upon by members of the community. Although such law systems include sanctions for law infractions, resolution tends to be reconciliatory rather than punitive. A number of African states practiced customary law many centuries prior to colonial influences. Following colonization, such laws were written down and incorporated to varying extents into the legal systems imposed by their colonial powers.

European Union Law - A sub-discipline of international law known as"supranational law" in which the rights of sovereign nations are limited in relation to one another. Also referred to as the Law of the European Union or Community Law, it is the unique and complex legal system that operates in tandem with the laws of the 27 member states of the European Union (EU). Similar to federal states, the EU legal system ensures compliance from the member states because of the Union's decentralized political nature. The European Court of Justice (ECJ), established in 1952 by the Treaty of Paris, has been largely responsible for the development of EU law. Fundamental principles of European Union law include: subsidiarity - the notion that issues be handled by the smallest, lowest, or least centralized competent authority; proportionality - the EU may only act to the extent needed to achieve its objectives; conferral - the EU is a union of member states, and all its authorities are voluntarily granted by its members; legal certainty - requires that legal rules be clear and precise; and precautionary principle - a moral and political principle stating that if an action or policy might cause severe or irreversible harm to the public or to the environment, in the absence of a scientific consensus that harm would not ensue, the burden of proof falls on those who would advocate taking the action.

French Law - A type of civil law that is the legal system of France. The French system also serves as the basis for, or is mixed with, other legal systems in approximately 50 countries, notably in North Africa, the Near East, and the French territories and dependencies. French law is primarily codified or systematic written civil law. Prior to the French Revolution (1789-1799), France had no single national legal system. Laws in the northern areas of present-day France were mostly local customs based on privileges and exemptions granted by kings and feudal lords, while in the southern areas Roman law predominated. The introduction of the Napoleonic Civil Code during the reign of Napoleon I in the first decade of the 19th century brought major reforms to the French legal system, many of which remain part of France's current legal structure, though all have been extensively amended or redrafted to address a modern nation. French law distinguishes between"public law" and "private law." Public law relates to government, the French Constitution, public administration, and criminal law. Private law covers issues between private citizens or corporations. The most recent changes to the French legal system - introduced in the 1980s - were the decentralization laws, which transferred authority from centrally appointed government representatives to locally elected representatives of the people.

International Law - The law of the international community, or the body of customary rules and treaty rules accepted as legally binding by states in their relations with each other. International law differs from other legal systems in that it primarily concerns sovereign political entities. There are three separate disciplines of international law: public international law, which governs the relationship between provinces and international entities and includes treaty law, law of the sea, international criminal law, and international humanitarian law; private international law, which addresses legal jurisdiction; and supranational law - a legal framework wherein countries are bound by regional agreements in which the laws of the member countries are held inapplicable when in conflict with supranational laws. At present the European Union is the only entity under a supranational legal system. The term"international law" was coined by Jeremy Bentham in 1780 in his Principles of Morals and Legislation, though laws governing relations between states have been recognized from very early times (many centuries B.C.). Modern international law developed alongside the emergence and growth of the European nation-states beginning in the early 16th century. Other factors that influenced the development of international law included the revival of legal studies, the growth of international trade, and the practice of exchanging emissaries and establishing legations. The sources of International law are set out in Article 38-1 of the Statute of the International Court of Justice within the UN Charter.

Islamic Law - The most widespread type of religious law, it is the legal system enforced in over 30 countries, particularly in the Near East, but also in Central and South Asia, Africa, and Indonesia. In many countries Islamic law operates in tandem with a civil law system. Islamic law is embodied in the sharia, an Arabic word meaning"the right path." Sharia covers all aspects of public and private life and organizes them into five categories: obligatory, recommended, permitted, disliked, and forbidden. The primary sources of sharia law are the Qur'an, believed by Muslims to be the word of God revealed to the Prophet Muhammad by the angel Gabriel, and the Sunnah, the teachings of the Prophet and his works. In addition to these two primary sources, traditional Sunni Muslims recognize the consensus of Muhammad's companions and Islamic jurists on certain issues, called ijmas, and various forms of reasoning, including analogy by legal scholars, referred to as qiyas. Shia Muslims reject ijmas and qiyas as sources of sharia law.

Mixed Law - Also referred to as pluralistic law, mixed law consists of elements of some or all of the other main types of legal systems - civil, common, customary, and religious. The mixed legal systems of a number of countries came about when colonial powers overlaid their own legal systems upon colonized regions but retained elements of the colonies' existing legal systems.

Napoleonic Civil Code - A type of civil law, referred to as the Civil Code or Code Civil des Francais, forms part of the legal system of France, and underpins the legal systems of Bolivia, Egypt, Lebanon, Poland, and the US state of Louisiana. The Civil Code was established under Napoleon I, enacted in 1804, and officially designated the Code Napoleon in 1807. This legal system combined the Teutonic civil law tradition of the northern provinces of France with the Roman law tradition of the southern and eastern regions of the country. The Civil Code bears similarities in its arrangement to the Roman Body of Civil Law (see Civil Law above). As enacted in 1804, the Code addressed personal status, property, and the acquisition of property. Codes added over the following six years included civil procedures, commercial law, criminal law and procedures, and a penal code.

Religious Law - A legal system which stems from the sacred texts of religious traditions and in most cases professes to cover all aspects of life as a seamless part of devotional obligations to a transcendent, imminent, or deep philosophical reality. Implied as the basis of religious law is the concept of unalterability, because the word of God cannot be amended or legislated against by judges or governments. However, a detailed legal system generally requires human elaboration. The main types of religious law are sharia in Islam, halakha in Judaism, and canon law in some Christian groups. Sharia is the most widespread religious legal system (see Islamic Law), and is the sole system of law for countries including Iran, the Maldives, and Saudi Arabia. No country is fully governed by halakha, but Jewish people may decide to settle disputes through Jewish courts and be bound by their rulings. Canon law is not a divine law as such because it is not found in revelation. It is viewed instead as human law inspired by the word of God and applying the demands of that revelation to the actual situation of the church. Canon law regulates the internal ordering of the Roman Catholic Church, the Eastern Orthodox Church, and the Anglican Communion.

Roman Law - A type of civil law developed in ancient Rome and practiced from the time of the city's founding (traditionally 753 B.C.) until the fall of the Western Empire in the 5th century A.D. Roman law remained the legal system of the Byzantine (Eastern Empire) until the fall of Constantinople in 1453. Preserved fragments of the first legal text, known as the Law of the Twelve Tables, dating from the 5th century B.C., contained specific provisions designed to change the prevailing customary law. Early Roman law was drawn from custom and statutes; later, during the time of the empire, emperors asserted their authority as the ultimate source of law. The basis for Roman laws was the idea that the exact form - not the intention - of words or of actions produced legal consequences. It was only in the late 6th century A.D. that a comprehensive Roman code of laws was published (see Civil Law above). Roman law served as the basis of law systems developed in a number of continental European countries.

Roman-Dutch Law - A type of civil law based on Roman law as applied in the Netherlands. Roman-Dutch law serves as the basis for legal systems in seven African countries, as well as Guyana, Indonesia, and Sri Lanka. This law system, which originated in the province of Holland and expanded throughout the Netherlands (to be replaced by the French Civil Code in 1809), was instituted in a number of sub-Saharan African countries during the Dutch colonial period. The Dutch jurist/philosopher Hugo Grotius was the first to attempt to reduce Roman-Dutch civil law into a system in his Jurisprudence of Holland (written 1619-20, commentary published 1621). The Dutch historian/lawyer Simon van Leeuwen coined the term"Roman-Dutch law" in 1652.

Spanish Law - A type of civil law, often referred to as the Spanish Civil Code, it is the present legal system of Spain and is the basis of legal systems in 12 countries mostly in Central and South America, but also in southwestern Europe, northern and western Africa, and southeastern Asia. The Spanish Civil Code reflects a complex mixture of customary, Roman, Napoleonic, local, and modern codified law. The laws of the Visigoth invaders of Spain in the 5th to 7th centuries had the earliest major influence on Spanish legal system development. The Christian Reconquest of Spain in the 11th through 15th centuries witnessed the development of customary law, which combined canon (religious) and Roman law. During several centuries of Hapsburg and Bourbon rule, systematic recompilations of the existing national legal system were attempted, but these often conflicted with local and regional customary civil laws. Legal system development for most of the 19th century concentrated on formulating a national civil law system, which was finally enacted in 1889 as the Spanish Civil Code. Several sections of the code have been revised, the most recent of which are the penal code in 1989 and the judiciary code in 2001. The Spanish Civil Code separates public and private law. Public law includes constitutional law, administrative law, criminal law, process law, financial and tax law, and international public law. Private law includes civil law, commercial law, labor law, and international private law.

United States Law - A type of common law, which is the basis of the legal system of the United States and that of its island possessions in the Caribbean and the Pacific. This legal system has several layers, more possibly than in most other countries, and is due in part to the division between federal and state law. The United States was founded not as one nation but as a union of 13 colonies, each claiming independence from the British Crown. The US Constitution, implemented in 1789, began shifting power away from the states and toward the federal government, though the states today retain substantial legal authority. US law draws its authority from four sources: constitutional law, statutory law, administrative regulations, and case law. Constitutional law is based on the US Constitution and serves as the supreme federal law. Taken together with those of the state constitutions, these documents outline the general structure of the federal and state governments and provide the rules and limits of power. US statutory law is legislation enacted by the US Congress and is codified in the United States Code. The 50 state legislatures have similar authority to enact state statutes. Administrative law is the authority delegated to federal and state executive agencies. Case law, also referred to as common law, covers areas where constitutional or statutory law is lacking. Case law is a collection of judicial decisions, customs, and general principles that began in England centuries ago, that were adopted in America at the time of the Revolution, and that continue to develop today.

Legislative branch This entry has three subfields. The description subfield provides the legislative structure (unicameral – single house; bicameral – an upper and a lower house); formal name(s); number of member seats; types of constituencies or voting districts (single seat, multi-seat, nationwide); electoral voting system(s); and member term of office. The elections subfield includes the dates of the last election and next election. The election results subfield lists percent of vote by party/coalition and number of seats by party/coalition in the last election (in bicameral legislatures, upper house results are listed first). In general, parties with less than four seats and less than 4 percent of the vote are aggregated and listed as "other," and non-party-affiliated seats are listed as "independent." Also, the entries for some countries include two sets of percent of vote by party and seats by party; the former reflects results following a formal election announcement, and the latter – following a mid-term or byelection – reflects changes in a legislature’s political party composition.



Of the approximately 240 countries with legislative bodies, approximately two-thirds are unicameral, and the remainder, bicameral. The selection of legislative members is typically governed by a country's constitution and/or its electoral laws. In general, members are either directly elected by a country's eligible voters using a defined electoral system; indirectly elected or selected by its province, state, or department legislatures; or appointed by the country's executive body. Legislative members in many countries are selected both directly and indirectly, and the electoral laws of some countries reserve seats for women and various ethnic and minority groups.



Worldwide, the two predominant direct voting systems are plurality/majority and proportional representation. The most common of the several plurality/majority systems is simple majority vote, or first-past-the-post, in which the candidate receiving the most votes is elected. Countries' legislatures such as Bangladesh's Parliament, Malaysia's House of Representatives, and the United Kingdom's House of Commons use this system. Another common plurality/majority system – absolute majority or two-round – requires that candidates win at least 50 percent of the votes to be elected. If none of the candidates meets that vote threshold in the initial election, a second poll or"runoff" is held soon after for the two top vote getters, and the candidate receiving a simple vote majority is declared the winner. Examples of the two-round system are Haiti's Chamber of Deputies, Mali's National Assembly, and Uzbekistan's Legislative Chamber. Other plurality/majority voting systems, referred to as preferential voting and generally used in multi-seat constituencies, are block vote and single non-transferable vote, in which voters cast their ballots by ranking their candidate preferences from highest to lowest.



Proportional representation electoral systems – in contrast to plurality/majority systems – generally award legislative seats to political parties in approximate proportion to the number of votes each receives. For example, in a 100-member legislature, if Party A receives 50 percent of the total vote, Party B, 30 percent, and Party C, 20 percent, then Party A would be awarded 50 seats, Party B 30 seats, and Party C 20 seats. There are various forms of proportional representation and the degree of reaching proportionality varies. Some forms of proportional representation are focused solely on achieving the proportional representation of different political parties and voters cast ballots only for political parties, whereas in other forms, voters cast
