Children go to the hospital for asthma more than twice as often in Cook County than anywhere else in the six-county metropolitan area. In general, the higher the African American population, the more kids are likely to be hospitalized.

Notes: Figures are the average annual number of child asthma hospitalizations from 1998 through 2002 for every 100,000 children under age 15.
