Rarely used in Public Administration studies, but useful and of fairly high quality, the Law Enforcement Management and Administrative Statistics (LEMAS) are machine-readable, available since 1987, and cover a variety of state and local LEAs:
Every three to four years, the Bureau of Justice Statistics (BJS) surveys a nationally representative sample of state and local law enforcement agencies. The surveys are conducted as part of the Law Enforcement Management and Administrative Statistics (LEMAS) program. Data include agency personnel, expenditures and pay, operations, community policing initiatives, equipment, computers and information systems, and written policies. The LEMAS survey has been conducted in 1987, 1990, 1993, 1997, 1999 (limited scope), 2000, 2003, and 2007.
Again, I can’t name a single PA study that has used these data. Maybe I should recommend these data for a student seeking dissertation material. Have any of y’all used them?
