NEW: America is more diverse than ever-but still segregated
This study was conducted by The Washington Post in 2018.
"The Post analyzed census data from 1990, 2000, 2010 and the latest estimates from the 2016 five-year American Community Survey. Using that data, we generated detailed maps of the United States using six race categories: black, white, Hispanic, Asian/Pacific Islander, Native American and multi-race/other for the available years."
