2010 Census data released so far this year show that 20 of the 25 cities that have at least 250,000 people and a 20% black population either lost more blacks or gained fewer in the past decade than during the 1990s. The declines happened in some traditional black strongholds: Chicago, Oakland, Atlanta, Cleveland and St. Louis.
The loss is fueled by three distinct trends:
• Blacks — many in the middle or upper-middle class — leaving cities for the suburbs.
• Blacks leaving Northern cities for thriving centers in the South.
