An excerpt from the Press Release.
“Presents summary data on the number of offenders under the supervision of the adult correctional systems in the United States at yearend 2011. Persons supervised by the adult correctional systems include those in the community under the authority of probation or parole agencies that supervise adults and those in the custody of state or federal prisons or local jails. The report provides statistics on the size and change in the total correctional population, by correctional status, during 2011. It presents a comparison between the rate of offenders under correctional supervision at yearend 2011 and 2000 and between the rates of offenders supervised in the community and those incarcerated at yearend 2011. The report also examines the impact of the changes in the community supervision and incarcerated populations during 2011 on the change observed in the total correctional population. Appendix tables provide additional information on prison populations, including prisoners under military jurisdiction and those in the custody of correctional authorities in the U.S. territories and commonwealths.
