Terms & Definitions: State and federal prisoners and prison facilities

Custody
To have custody of a prisoner, a state or the Federal Bureau of Prisons (BOP) must physically hold that person in one of its facilities. A locality, state, or the BOP may hold inmates over whom a different government maintains jurisdiction.

Custody count
The number of offenders in custody. To have custody of a prisoner, a state or the Federal Bureau of Prisons (BOP) must physically hold that person in one of its facilities. A locality, state, or the BOP may have custody of a prisoner over whom a different government maintains jurisdiction.

Design capacity
The number of inmates that planners or architects intended for the facility.

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.

Imprisonment rate
The number of prisoners under state or federal jurisdiction sentenced to more than one year, per 100,000 U.S. residents.

Incarcerated population
Incarcerated population is the population of inmates confined in a prison or a jail. This may also include halfway-houses, bootcamps, weekend programs, and other facilities in which individuals are locked up overnight.

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.

Jurisdiction count
Includes prisoners under legal authority of state or federal correctional authorities who are housed in prison facilities (e.g., prisons, penitentiaries and correctional institutions; boot camps; prison farms; reception, diagnostic, and classification centers; release centers, halfway houses, and road camps; forestry and conservation camps; vocational training facilities; prison hospitals; and drug and alcohol treatment facilities for prisoners), regardless of which state they are physically held in. This number also includes prisoners who are temporarily absent (less than 30 days), out to court, or on work release; housed in local jails, private facilities, and other states' or federal facilities; serving a sentence for two jurisdictions at the same time. This count excludes prisoners held in a state or federal facility for another state or the Federal Bureau of Prisons. However, prisoners housed in another state and under the legal authority of the governing state are included.

Movement
In corrections, a movement refers to an admission or a release from a status such as prisoner, parolee, or probationer. Unless specifically noted, a transfer between facilities does not count as a movement.

Operational capacity
The number of inmates that can be accommodated based on a facility's staff, existing programs, and services.

Parole
Parole refers to criminal offenders who are conditionally released from prison to serve the remaining portion of their sentence in the community. Prisoners may be released to parole by a parole board decision (discretionary release/discretionary parole), according to provisions of a statute (mandatory release/mandatory parole), through other types of post-custody conditional supervision, or as the result of a sentence to a term of supervised release. In the federal system, a term of supervised release is a sentence to a fixed period of supervision in the community that follows a sentence to a period of incarceration in federal prison, both of which are ordered at the time of sentencing by a federal judge. Parolees can have a number of different supervision statuses including active supervision, which means they are required to regularly report to a parole authority in person, by mail, or by telephone. Some parolees may be on an inactive status which means they are excluded from regularly reporting, and that could be due to a number of reasons. For instance, some may receive a reduction in supervision, possibly due to compliance or meeting all required conditions before the parole sentence terminates, and therefore may be moved from an active to inactive status. Other supervision statues include parolees who only have financial conditions remaining, have absconded, or who have active warrants. Parolees are also typically required to fulfill certain conditions and adhere to specific rules of conduct while in the community. Failure to comply with any of the conditions can result in a return to incarceration.

Prison
Compared to jail facilities, prisons are longer-term facilities owned by a state or by the Federal Government. Prisons typically hold felons and persons with sentences of more than a year; however, the sentence length may vary by state. Six states (Connecticut, Rhode Island, Vermont, Delaware, Alaska, and Hawaii) have an integrated correctional system that combines jails and prisons. There are a small number of private prisons, facilities that are run by private prison corporations whose services and beds are contracted out by state or federal governments.

Prisoners
Prisoners are inmates confined in long-term facilities run by the state or federal government or private agencies. They are typically felons who have received a sentence of incarceration of 1 year or more. (Sentence length may vary by state because a few states have one integrated prison system in which both prison and jail inmates are confined in the same types of facilities.)

Private prisons
Prison facilities run by private prison corporations whose services and beds are contracted out by state governments or the Federal Bureau of Prisons.

Rated capacity
The number of beds or inmates assigned by a rating official to institutions within the jurisdiction.

Sentenced prisoners
Prisoners under the jurisdiction of state and federal correctional authorities who have been given a sentence of more than one year.

State prisons
Prison facilities run by state correctional authorities. Prisoners housed in these facilities are under the legal authority of the state government and generally serving a term of more than 1 year.

Total correctional population
Total correctional population is the population of persons incarcerated, either in a prison or a jail, and persons supervised in the community, either on probation or parole.

Total incarceration rate
The number of inmates held in the custody of state or federal prisons or in local jails, per 100,000 U.S. residents.

Total inmates in custody count
To have custody of a prisoner, a state or the Federal Bureau of Prisons must hold that person in one of its facilities. A state may have custody of a prisoner over whom another state maintains jurisdiction. This count includes inmates held in any public facility run by a state or the Federal Bureau of Prisons, including halfway houses, camps, farms, training/treatment centers, and hospitals. This number includes the number of inmates held in local jails as reported by correctional authorities in the Annual Survey of Jails.
