Census of State and Local Law Enforcement Agencies (CSLLEA), 2004 [United States]

To ensure an accurate sampling frame for its Law
Enforcement Management and Administrative Statistics (LEMAS) survey,
the Bureau of Justice Statistics sponsors a census of the
nation's state and local law enforcement agencies, known
as the Directory Survey. This census, which is conducted every four years, includes all state and local law enforcement
agencies operating nationwide that are publicly funded and employ at least one full-time or part-time sworn officer with general arrest powers. As in previous
years, the 2004 census collected data on the number of sworn
and nonsworn personnel employed by each agency, including both
full-time and part-time employees. The pay period that included September
30, 2004, was the reference date for all personnel data. Variables include personnel totals, type of government, type of agency, and whether the agency had the legal authority to hold a person beyond arraignment for 48 or more hours.
Previous censuses were conducted in 1986 (DIRECTORY OF LAW
