Law Enforcement Core Statistics (LECS) Program

The LECS is designed to capture critical data on the management and administration of law enforcement agencies in a systematic and efficient manner through the sequential administration of the LEMAS, CSLLEA, and FLEO data collections. Law Enforcement Management and Administrative Statistics (LEMAS) survey The LEMAS survey is the most systematic and comprehensive source of national data on law enforcement personnel, expenditures and pay, operations, equipment, computers and information systems, and policies and procedures. It provides national estimates for all state and local general purpose law enforcement agencies (i.e., any public agency with one or more sworn officers whose patrol and enforcement responsibilities are primarily delimited by the boundaries of a municipal, county, or state government) based on a nationally representative sample of agencies. Census of State and Local Law Enforcement Agencies The CSLLEA has been conducted regularly since 1992. It enumerates all publicly funded state, county, and local LEAs operating in the United States and provides complete personnel counts. from about 20,000 law enforcement agencies. Historically, the CSLLEA has achieved a 99% response rate. For purposes of the CSLLEA, a law enforcement agency is a publicly funded government entity responsible for enforcing laws, maintaining public order, and promoting public safety. Census of Federal Law Enforcement Officers (FLEO) The FLEO was conducted about every 2 years from 1993 to 2008. In 2014, the FLEO was administered in conjunction with the CSLLEA and will continue to be on the same collection cycle as the CSLLEA. The FLEO enumerates all federal law enforcement agencies (about 110 agencies) operating in the United States.
