List of U.S. states by Gini coefficient

The Gini coefficient is a measure of inequality of variance. It is often applied to measure inequality of incomes in a particular area.

A score of "0" on the Gini coefficient represents complete equality, i.e., every person has the same income. A score of 1 would represent complete inequality, i.e., where one person has all the income and others have none. Therefore, a lower Gini score is roughly associated with a more equal distribution of income, and vice versa.

The information was tabulated in 2010 from data from the American Community Survey conducted by the US Census Bureau. Utah shows the flattest income distribution while the District of Columbia and New York State have the largest income disparities between wage earners in all income categories.

U.S. income inequality was at its highest level since the United States Census Bureau began tracking household income in 1967. The U.S. also has the greatest disparity among Western industrialized nations.
