"Segregation itself, the decennial census report indicates, is only decreasing slowly, although the dividing lines are shifting as middle-income blacks, Latinos and Asians move to once all-white suburbs -- whereupon whites often move away, turning older suburbs into new, if less distressed, ghettos.
We may think of segregation as a matter of ancient Southern history: lunch counter sit-ins, bus boycotts and Ku Klux Klan terrorism. But as the census numbers remind us, Northern cities have long had higher rates of segregation than in the South, where strict Jim Crow laws kept blacks closer to whites, but separate from them. Where you live has a big impact on the education you receive, the safety on your streets, and the social networks you can leverage."
