Continuing a generational slide, the rich in the U.S. got richer over the last decade, and the poor got poorer. A Social Explorer analysis of 2006-10 and 2016-20 American Community Survey data finds the Gini coefficient, a common measure of inequality, rose more than 3 percent over the decade. The coefficient, a number between 0 and 1 (0 means income is distributed evenly; 1 means a single household has all the income), rose to 0.48 for the latest survey period.
The gap between rich and poor was most pronounced in Harding County, N.M., which recorded a Gini of 0.696. It was trailed by East Carroll Parish, La. (0.652), Humphreys County, Miss. (0.636), Buena Vista City, Va. (0.616), and Bossier Parish, La. (0.611). New York County, the population center of the nation’s largest metro, had the sixth-highest Gini coefficient at 0.595.
