From an article by Thomas Edsell in today's New York Times "Whose Neighborhood Is It Anyway?":
In the case of white suburban Detroit, Orfield, of the University of Minnesota, points out that just as racial integration was temporary in Detroit neighborhoods, so it appears to be in its suburbs. Half of the suburbs that were racially diverse in 2000 had become predominantly nonwhite in 2010, and most of the integrated suburbs in 2010 were in the process of resegregation.

Southfield, Mich., for example, which had been 0.7 percent black in 1970, by 2010 had become 70.3 percent black, and its schools nearly 95 percent black. Over the same time period, Ecorse, a suburb southwest of Detroit, went from 0.4 percent black to 44.5 percent, and its school system to 72 percent black; Oak Park from 0.6 to 57.4, and its school system to 95 percent black; Harper Woods from 0.3 to 45.6, and its school system to 88 percent black.
