A new report released by the U.S. Census Data shows that the income gap between Americans is greater than at any other time on record. The report found that the top-earning 20% of Americans received 49.4% of the country's total income. Conversely, those living below the poverty line earned 3.4% of the national income. This is the highest disparity of wealth among all Western industrialized nations.

New data, collated by the OECD, shows the levels of inequality across all 36 member states.

Inequality is measured on a scale between zero and one, where zero represents perfect equality and one represents the maximum possible inequality (if one person were to have everything and everybody else had nothing).

Each country has two scores: one for market income inequality, which measures salaries, capital and property income, and one for income after redistribution, which also takes into account levelling factors, such as taxes paid, cash benefits and social security.

All countries see a reduction in inequality after this redistribution is considered, although the amount by which inequality is reduced varies considerably.
