Income inequality in America widened “significantly” last year, according to a U.S. Census Bureau report published Thursday.

A measure of inequality known as the Gini index rose to 0.485 from 0.482 in 2017, according to the bureau’s survey of household finances. The measure compares incomes at the top and bottom of the distribution, and a score of 0 is perfect equality.
