List of countries by inequality-adjusted income

This is a list of countries by inequality-adjusted income, as defined and measured by the United Nations Development Programme (UNDP).^[1] The income index is one component of the Human Development Index (HDI), but is also used separately.^[2]

Adjusting income for inequality based on the Gini coefficient was first proposed by Amartya Sen in 1976.^[3] The UN first applied the adjustment to income data in 1993, before it was later expanded to the general HDI.^[4]
