"The rate of AIDS-related deaths in state prisons among inmates ages 15 to 54 declined sharply between 2001 and 2009, compared to the more modest decline observed among the same age group in the U.S. general population. As a result, the AIDS-related death rate in state prisons fell below the rate in the U.S. general population in 2009. Between 2001 and 2009, the AIDS-related death rate among state prisoners ages 15 to 54 declined from 22 deaths per 100,000 inmates to 6 per 100,000, while the rate among that age group in the general population declined from 9 per 100,000 to 7 per 100,000."
