This report summarizes data on populations supervised by probation or parole agencies and those incarcerated in state or federal prisons or in the custody of local jails. It presents data on the number of persons supervised by adult correctional systems from 2010 to 2020 and on their correctional status (i.e., in prison, in local jail, on parole, or on probation).
Findings are based on data from several BJS data collections, including the Annual Probation Survey and Annual Parole Survey, Annual Survey of Jails, Census of Jails, and National Prisoner Statistics program.
Correctional Populations in the United States, 2020 ? Statistical Tables (NCJ 303184) was written by BJS Statisticians Rich Kluckow, DSW, and Zhen Zeng, Ph.D. The report, related documents, and additional information about BJS?s statistical publications and programs are available on the BJS website at bjs.ojp.gov.
The new CSAT-Prisoners is an interactive data visualization dashboard, which replaces and enhances the core functionality of the previous data tool. For the first time, the dashboard combines data from the National Corrections Reporting Program (NCRP) and National Prisoner Statistics (NPS) program. This dashboard provides data users central access to more comprehensive, in-depth, state-level data on persons in state prison, including data by age, sex, race or ethnicity, offense, sentence length, time served in prison, and type of admission and release. Additionally, data users can access preformatted frequently requested charts or generate custom statistics, figures, and maps on prison admissions, prison releases, and yearend prison populations for data between 1978 and 2019. The NPS and NCRP are BJS?s flagship data collections measuring the size and composition of state and federal prison populations on an annual basis. The two collections complement each other by obtaining aggregate and detailed individual-level information on prisoners, which is used to describe and compare the prison population over time.
The Bureau of Justice Statistics has released a dataset on the nation?s local jails and the 12 Federal Bureau of Prisons (BOP) detention facilities that function as jails, through the National Archive of Criminal Justice Data. This census collected data on the following topics:
- inmate counts, sex, race, Hispanic origin, conviction status, and offense severity
- juveniles and non-U.S. citizens held in jail
- jail admissions, releases, average daily population, capacity, and staffing
- opioid use disorder testing and treatment programs.
The Bureau of Justice Statistics of the U.S. Department of Justice is the principal federal agency responsible for collecting, analyzing, and disseminating reliable statistics on crime and criminal justice in the United States. Doris J. James is the acting director.
