Summary View help for Summary
The data in this collection represent the sampling frame used to draw a national sample of law enforcement agencies. The sampling frame was a composite of law enforcement agencies in existence between June 1993 and June 1997 and was used in a subsequent study, a national evaluation of Title I of the 1994 Crime Act. The evaluation was undertaken to (1) measure differences between Community Oriented Policing Services (COPS) grantees and nongrantees at the time of application, (2) measure changes over time in grantee agencies, and (3) compare changes over time between grantees and nongrantees. The sampling frame was comprised of two components: (a) a grantee component consisting of agencies that had received funding during 1995, and (b) a nongrantee component consisting of agencies that appeared potentially eligible but remained unfunded through 1995.

The sampling frame, which was a composite of law enforcement agencies in existence between June 1993 and June 1997, was comprised of two components. The first, a grantee component, consisted of agencies that had received funding during 1995. A grantee list, created in April 1996, was obtained from applicant records from the grants management database from the Office of Community Oriented Policing Services (COPS). Specifically, COPS provided databases for the following programs: (1) Funding Accelerated for Small Towns (FAST), (2) Accelerated Hiring, Education, and Deployment (AHEAD), (3) Universal Hiring Program (UHP), and (4) Making Officer Redeployment Effective (MORE). These databases included, among other things, the applicant's originating agency identifier (ORI) and the status for each submitted application. An application was considered "funded" if the status variable indicated that the application was accepted by COPS for funding by December 31, 1995. Because a single agency could have had applications accepted in any of the multiple programs, the various databases were flattened so that each agency represented a single record. An agency was added to the grantee component of the sampling frame if at least one of its applications was deemed "funded." The second component of the sampling frame was a nongrantee component, which consisted of agencies that appeared potentially eligible but remained unfunded through 1995. To determine the nongrantee component of the sampling frame, a master list of candidates for inclusion as eligible nongrantees was compiled in July 1998 consisting of agencies pulled from the following sources: (1) the National Crime Information Center (NCIC), (2) the Uniform Crime Reporting (UCR) Program, and (3) the National Law Enforcement Agency List (NLEAL). NLEAL, which was a subset of the Justice Agency List, contained the most comprehensive list of law enforcement agencies in existence at any point between June 1993 and June 1997. To reduce this master list, "clearly ineligible" agencies were removed using various automated algorithms. Researchers also used a combination of visual inspection and computer matching on the agencies from the NCIC and UCR to further eliminate "clearly ineligible" agencies. This reduced master list was then merged with the flattened grantee list and any agency appearing on both lists was removed from the nongrantee master list. The resulting agencies from the reduced master list (making up the nongrantee component), along with the grantee list (making up the grantee component) comprised the sampling frame.

Variables include agency identification number, type of agency, FIPS code, Office of Community Policing Service eligibility, COPS funding status, total number of full- and part-time employees, total number of full- and part-time sworn employees, population, and sheriff agencies' eligibility for grants, based on one of three criteria: (1) the sheriff agency already had a Community Oriented Policing Services (COPS) grant, (2) another sheriff agency in the same state received a COPS grant, or (3) the sheriff agency was located in a state where sheriff agencies were known to have law enforcement authority.

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.
2001-08-06 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:
