"At midyear 2005 more than half of all prison and jail inmates had a mental health problem, including 705,600 inmates in State prisons, 78,800 in Federal prisons, and 479,900 in local jails. These estimates represented 56% of State prisoners, 45% of Federal prisoners, and 64% of jail inmates. The findings in this report were based on data from personal interviews with State and Federal prisoners in 2004 and local jail inmates in 2002. Mental health problems were defined by two measures: a recent history or symptoms of a mental health problem. They must have occurred in the 12 months prior to the interview. A recent history of mental health problems included a clinical diagnosis or treatment by a mental health professional. Symptoms of a mental disorder were based on criteria specified in the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV)."
