This map shows current world life expectancy at birth. Life expectancy at birth is the expected average number of years to be lived by a group of people born in the same year, if mortality at each age remains constant in the future.

Current World World Life Expectancy at Birth (total population): 67.07 years (2011 est.)

male: 65.21 years (2011 est.)

female: 69.05 years (2011 est.)

Life expectancy at birth is also a measure of overall quality of life in a country and summarizes the mortality at all ages. It can also be thought of as indicating the potential return on investment in human capital and is necessary for the calculation of various actuarial measures.
