In 2003, 6.9 million people were under some form of correctional supervision including:
Probation - court ordered community supervision of convicted offenders by a probation agency. In many instances, the supervision requires adherence to specific rules of conduct while in the community.
Prison - confinement in a State or Federal correctional facility to serve a sentence of more than 1 year, although in some jurisdictions the length of sentence which results in prison confinement is longer.
Jail - confinement in a local jail while pending trial, awaiting sentencing, serving a sentence that is usually less than 1 year, or awaiting transfer to other facilities after conviction.
Parole - community supervision after a period of incarceration. These data include only adults who are on active or inactive parole supervision or some other form of conditional release, including mandatory release, following a term of incarceration.
