In 1960, there were no African Americans living in seven Chicago community areas. Today, blacks live in each of the city’s 77 communities. However, segregation patterns have largely remained the same in 58 of the city’s community areas. In 1960, blacks made up fewer than 10 percent or comprised at least 90 percent of the population of these neighborhoods. In 2000, the same was true in 54 community areas.
