About this Topic

BJS collects data on the characteristics and movements of the federal prison population through the National Prisoner Statistics, the Federal Justice Statistics Program, and the Survey of Inmates in State and Federal Facilities. See Corrections Data Sources for more information. The federal prisoner population differs from prisoners held in jail or state correctional facilities most notably by offense, conviction status, length of stay, and offense distribution. 

Note that jurisdiction and custody numbers for federal prisoners now include counts for sentenced felons from the District of Columbia. After 2001, responsibility for sentenced felons from the District of Columbia was transferred to the Federal Bureau of Prisons.

Terms & Definitions

Federal prisons Prison facilities run by the Federal Bureau of Prisons (BOP). Prisoners housed in these facilities are under the legal authority of the federal government. This excludes private facilities under exclusive contract with BOP.
 
Imprisoned population The population of inmates confined in prison or other facilities under the jurisdiction of the state or Federal Bureau of Prisons.
 
Institutional corrections Institutional corrections refers to those persons housed in secure correctional facilities. There are many different types of correctional facilities, operated by different government entities. Local jails are operated by county or municipal authorities, and typically hold offenders for short periods ranging from a single day to a year. Prisons serve as long-term confinement facilities and are only run by the 50 state governments and the federal Bureau of Prisons. Private correctional facilities also operate under contracts for a wide variety of local, state and federal agencies. Other correctional facilities are operated by special jurisdictions such as the U.S. Armed Forces, U.S. territories and federal agencies such as Immigrations and Customs Enforcement (ICE).
 
Jurisdiction Jurisdiction generally refers to a unit of government or to the legal authority to exercise governmental power. In corrections, it refers to the government which has legal authority over an inmate (state or federal). Prisoners under a given state's jurisdiction may be housed in another state or local correctional facility.
 
Operational capacity The number of inmates that can be accommodated based on a facility's staff, existing programs, and services.
