Florio examined the racial and ethnic makeup of 52 metropolitan areas by census tract and geographic distance from the city center. He found that in all but three of the 52 metropolitan areas the average person — of any race or ethnicity — lived farther from the city center in 2010 than in 1990. During this period, each of the four major racial and ethnic groups moved, to some degree, away from the city center, but Blacks remained closest, and Whites moved farthest.
“While the U.S. has become more diverse, and there are fewer hypersegregated neighborhoods, there is still a racial dynamic to sprawl — one in which the new suburbs on the periphery of cities tend to be generally White,” Florio reports.
