List of countries by income equality


This is a list of countries or dependencies by income inequality metrics, including Gini coefficients. The Gini coefficient is a number between 0 and 1, where 0 corresponds with perfect equality and 1 corresponds with perfect inequality.
Income distribution can vary greatly from wealth distribution in a country. Income from black market economic activity is not included and is the subject of current economic research.

UN, World Bank and CIA list – income ratios and Gini indices

Key:
;R/P 10%: The ratio of the average income of the richest 10% to the poorest 10%.
;R/P 20%: The ratio of the average income of the richest 20% to the poorest 20%.
;Gini: Gini index, a quantified representation of a nation's Lorenz curve. A Gini index of 0% expresses perfect equality, while index of 100% expresses maximal inequality.
;UN: Data from the United Nations Development Programme.
;World Bank: Data from the World Bank.
;CIA: Data from the Central Intelligence Agency's The World Factbook.
Other estimates for the World: Gini = 63.0 in 2006.
