Produces annual national- and state-level data on the number of prisoners in state and federal prison facilities. Aggregate data are collected on race and sex of prison inmates, inmates held in private facilities and local jails, system capacity, noncitizens, and persons age 17 or younger. Findings are released in the Prisoners series and the Corrections Statistical Analysis Tool (CSAT) - Prisoners. Data are from the 50 state departments of correction, the Federal Bureau of Prisons, and until 2001, the District of Columbia. After 2001, persons sentenced under the District of Columbia criminal code were housed in federal facilities.
