The Department of Justice's Survey of Inmates in State and Federal Correctional Facilities (2004) and Survey of Inmates in Local Jails (2002) indicate that the rate of mental health problems is highest in local correctional facilities. In this study a mental health problem was defined as receiving a clinical diagnosis or treatment by a mental health professional. Nearly two thirds of jail inmates (64.2 percent) in local jails satisfied the criteria for a mental health problem currently or in the previous year.
