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.

Alternate Title: Sample Survey of Law Enforcement Agencies
Principal Investigator(s): United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
This survey, the second in the Bureau of Justice Statistics' program on Law Enforcement and Administrative Statistics (LEMAS), presents information on four types of general-purpose law enforcement agencies: state police, local police, special police, and sheriff's departments. Variables include size of the population served by the police or sheriff's department, levels of employment and spending, various functions of the department, average salary levels for uniformed officers, and other matters related to management and personnel.
These data are available to the general public.

Scope of Study
Geographic Coverage: United States
Date of Collection:
Universe: All state, local, special, and sheriff's law enforcement agencies in the United States.
Data Types: survey data
Data Collection Notes:
The data map is provided as an ASCII text file, and the codebook is provided by ICPSR as a Portable Document Format (PDF) file.
Sample: All primary general-purpose state police agencies were chosen. All sheriff's departments, local police departments, and special agencies with more than 100 sworn officers were chosen. A stratified random sampling method was used in selecting smaller agencies.
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:
- Performed consistency checks.
- Created variable labels and/or value labels.
- Standardized missing values.
- Performed recodes and/or calculated derived variables.
- Checked for undocumented or out-of-range codes.
