Income Gap Inequality in the U.S.

MONDAY, JAN 11, 2021

Nine of the 10 U.S. counties with the greatest gaps between rich and poor grew even more unequal during the last decade, according to a Social Explorer analysis of newly released 2015-19 American Community Survey data. Only New York County – home to the nation’s financial center and the sixth most-unequal place in the U.S. – reported shrinking in the gap between rich and poor.

The gap is measured by the Gini coefficient, which assigns a value between 0 (meaning wealth is distributed evenly) and 1 (wealth is controlled by one household). The U.S. has a Gini of 0.48, an increase from the 0.47 recorded in 2010. East Carroll Parish, La., the nation’s most unequal county, has a Gini of 0.71, a significant increase from the 0.65 reported in 2010. Use Social Explorer’s online, easy-to-use mapping tools to look at the changes in income inequality over the last decade in your county.
