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 1999 Census of Jails.
Data Types: survey data
Data Collection Notes:
The codebook and data collection instrument are provided by ICPSR as Portable Document Format (PDF) files. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided on the ICPSR Web site.
Sample: Based on information from the 1999 Census of Jails, a sample of jail jurisdictions was selected for the 2001 survey. The sample included all public and private jails in 878 selected jail jurisdictions (in which there were a total of 948 reporting units) and 47 regional jails. The sample selection was designed to yield a coefficient of variation of 1 percent of average daily population and one-day inmate population. Large jails and regional jails were 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.
Original ICPSR Release: 2004-02-24
- 2005-11-04 On 2005-03-14 new files were added to one or more datasets. These files included additional setup files as well as one or more of the following: SAS program, SAS transport, SPSS portable, and Stata system files. The metadata record was revised 2005-11-04 to reflect these additions.
