The National Corrections Reporting Program gathers data on prisoners entering and leaving the custody or supervision of state and federal authorities. The dataset is comprised of four types of data: prisoners who were admitted to prison (Part 1), released from prison (Part 2), released from parole (Part 3), or in prison at year end (Part 4).
The National Prison Statistics (NPS) program was established in 1926 by the Bureau of the Census in response to a congressional mandate to compile national information on the populations confined in correctional institutions. This program described the characteristics and counts of prison inmates during each calendar year. Since its initiation, responsibility for this program has shifted among several agencies -- in 1950 it was transferred to the Federal Bureau of Prisons and to the Law Enforcement Assistance Administration in 1971. Since 1972, the Bureau of Census, under agreement with the Department of Justice, has had responsibility for compiling the statistical data. Census staff negotiates directly with each state, assembles and edits the data, and prepares the data for analysis and publication.

Mode of Data Collection:
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:
Checked for undocumented or out-of-range codes.
