BJS collects data on agency characteristics through two core law enforcement agency surveys: the Census of State and Local Law Enforcement Agencies (CSLLEA) and the Law Enforcement Management and Administrative Statistics (LEMAS) survey.
Census of State and Local Law Enforcement Agencies
For over 30 years, BJS has been the authoritative source for national statistics regarding the personnel, operations, policies, and procedures of law enforcement agencies.
Law enforcement describes the agencies and employees responsible for enforcing laws, maintaining public order, and managing public safety. The primary duties of law enforcement include the investigation, apprehension, and detention of individuals suspected of criminal offenses. Some law enforcement agencies, particularly sheriff’s offices, also have a significant role in the detention of individuals convicted of criminal offenses.
