Deaths in New York City jails, 2001-2009.

Approximately 90,000 inmates are admitted annually to the New York City jail system, many of whom require a high level of medical or mental health services. According to our analysis of deaths in custody from 2001 to 2009, crude death rates have dropped significantly despite the increasing age of the population. Falling HIV-related mortality appears to contribute to this change. Other observations include low rates of suicide across all 9 years and increasing age of the population in recent years.
