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. Office of Justice Programs. Bureau of Justice Statistics
To ensure an accurate sampling frame for its Law Enforcement Management and Administrative Statistics (LEMAS) survey, the Bureau of Justice Statistics periodically sponsors a census of the nation's state and local law enforcement agencies. This census, known as the Directory Survey, gathers data on all police and sheriffs' departments that are publicly funded and employ at least one full-time or part-time sworn officer with general arrest powers. This data collection, compiled in July 1992, represents the second such census, with the first occurring in 1986 (DIRECTORY OF LAW ENFORCEMENT AGENCIES, 1986: [UNITED STATES] [ICPSR 8696]). Variables include personnel totals, type of agency, geographic location of agency, and whether the agency had the legal authority to hold a person beyond arraignment for 48 or more hours.
These data are freely available.
