Date of Collection:
Unit of Observation:
All sampled jail jurisdictions (i.e., counties, municipalities, boroughs, etc.) identified through from the 2005 Census of Jail Inmates.
Based on information from the 2005 Census of Jails, a sample of individual jail reporting units was selected for the 2009 survey. The sample included public and private jails in 874 selected jail jurisdictions. 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.
Mode of Data Collection:
The response rate for the survey was 100 percent for the following critical data items: confined persons (CONFPOP), number of adult male and adult
female inmates (ADMALE, ADFEML), average daily population (ADP), and total rated capacity of
jails (RATCAP). Extensive follow-up, including additional mail and fax requests and repeated telephone
contacts, resulted in a nearly 100 percent response rate for the number of juvenile male and juvenile female
inmates (JUVMALE, JUVFEML). The response rate was around 90 percent for data on male and female inmates by conviction status (CONVMALE, CONVFML, UNCONVML, UNCONVFM), and for the number of inmates by race and Hispanic origin (WHITE, BLACK, HISP, AMINDALK, ASIAN, HAWPAC). The response rate for admissions to and releases from jail was around 92 percent.
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:
Standardized missing values.
Checked for undocumented or out-of-range codes.
