National Archive of Criminal Justice Data
This dataset is maintained and distributed by the National Archive of Criminal Justice Data (NACJD), the criminal justice archive within ICPSR. NACJD is primarily sponsored by three agencies within the U.S. Department of Justice: the Bureau of Justice Statistics, the National Institute of Justice, and the Office of Juvenile Justice and Delinquency Prevention.
Annual Survey of Jails: Jurisdiction-Level Data, 2006 (ICPSR 20368)
Principal Investigator(s): United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
This collection provides annual data on jail populations across the nation and examines the "spillover" on local jails resulting from the dramatic growth in federal and state prison populations. These data are used to track growth in the number of jails and their capacities nationally, changes in the demographics of the jail population (including sex, race, and adult or juvenile status), supervision status of persons held, prevalence of crowding issues, and a count of non-United States citizens within the jail population.
These data are freely available.

Scope of Study
Geographic Coverage: United States
Date of Collection:
Universe: All jail jurisdictions (i.e., counties, municipalities, boroughs, etc.) identified through the 2005 Census of Jails.
Data Types: survey data
Sample: Based on information from the 2005 Census of Jails, a sample of jail jurisdictions was selected for the 2006 survey. The sample included public and private jails in 874 selected jail jurisdictions including 63 regional jails. A stratified random sample of county or city jurisdictions was stratified by average daily population (ADP) as reported by the 2005 Census of Jails. Large jails and regional jails were included in the sample with certainty.
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.
