Researchers have also analyzed income inequality within other groups, such as by. There was little change from 2000 to 2016, with the notable exception of gains for lower-income Hispanics.

But there were two distinct episodes in this period, with gains from 1970 to 2000 followed by setbacks from 2000 to 2016. In 1970, Americans near the top had 6.9 times as much income as those near the bottom, $63,512 compared with $9,212. The Gini coefficient, perhaps the most commonly used measure of income inequality, looks at the share of aggregate income held by each individual.
