American neighborhoods are desegregating slightly, but the situation is worse for children. Black and Hispanic children are more likely to be residentially segregated than minority adults.

Schools are resegregating, too. The percentage of black students who are attending schools that are 90 to 100 percent minority went down in the South in the 1970s and 1980s, but now is shooting up. In the Northeast, the percentage of black students in these schools has been climbing for decades.

Even the workplace is showing signs of regression. Big companies are still reasonably integrated, but newer, smaller businesses are more segregated, often largely white, black or Hispanic.
