Washington Post: “…Even as the United States becomes increasingly diverse, neighborhood segregation patterns persist in large urban areas, including in the Washington metro region, according to five-year trend data from the Census Bureau. Segregation has remained most entrenched between black and white residents, while segregation between whites and Hispanics and whites and Asians is more fluid, according to an analysis of the bureau’s latest American Community Survey data. Some of the starkest black-white urban divide can be seen in Midwestern and Northeastern cities with long-concentrated and slow-growing black populations, including Buffalo, Chicago, Cleveland, Detroit, Milwaukee, New York and St. Louis, said William Frey, a senior demographer at the Brookings Institution, who analyzed the data. These cities all have segregation levels above 70, meaning that 70 percent or more of black residents would have to move into a different neighborhood to fully integrate the city. But overall, segregation was down since 2000, when several metropolitan areas had levels above 80. The urban area with the lowest black-white segregation level is Las Vegas, at 39.5. In the Washington region, the black-white segregation level was 61.3, down from 63.6 in 2000…”
