America has been talking about racial segregation and its effects for decades. Now another kind of separation is grinding away at America’s neighborhoods: income segregation, where people are separated by their wealth, or lack of it.
More than one-third of families in large metropolitan areas now live in neighborhoods of concentrated affluence or concentrated poverty, and middle-class neighborhoods have become less common, according to new research by a Cornell sociologist and her colleague. The effect on children could be critical, they say.
Kendra Bischoff, Cornell assistant professor of sociology, and Sean Reardon of Stanford University found that the percentage of families living in very rich neighborhoods more than doubled, from 6.6 percent to 15.7 percent, between 1970 and 2012. At the same time, the percentage of families in traditional middle-income neighborhoods fell from 65 percent to 41 percent.
