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.
Principal Investigator(s): United States Department of Justice. Bureau of Justice Statistics
This survey, the third in the Bureau of Justice Statistics' program on Law Enforcement and Administrative Statistics (LEMAS), presents information on five types of general-purpose law enforcement agencies: state police, county police, special police (state and local), municipal 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, policies and programs, and other matters related to management and personnel.
These data are freely available.

This survey was conducted by the United States Department of Commerce, Bureau of the Census.
Sample: A nationally representative sample of the nearly 17,000 publicly funded state and local law enforcement agencies with 100 or more sworn officers. The survey also included a nationally representative sample of agencies that employed fewer than 100 officers. A stratified random sampling method was used in selecting the smaller agencies.A nationally representative sample of the nearly 17,000 publicly funded state and local law enforcement agencies with 100 or more sworn officers.

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.
- Standardized missing values.
- Performed recodes and/or calculated derived variables.
- Checked for undocumented or out-of-range codes.
