Law Enforcement Core Statistics (LECS)


For over 25 years, the Bureau of Justice Statistics (BJS) has been the authoritative source for national statistics regarding the personnel, operations, policies, and procedures of law enforcement agencies (LEAs). These data are currently collected through BJS’ core law enforcement data collection programs: the Law Enforcement Management and Administrative Statistics (LEMAS) survey, the Census of State and Local Law Enforcement Agencies (CSLLEA), and the Census of Federal Law Enforcement Officers (FLEO).


Through the Law Enforcement Core Statistics Program (LECS), BJS is seeking to combine these collections into a cohesive law enforcement collection program and reshape their content to focus on agency performance as well as measures needed to better describe contemporary topics related to agency staffing, regulations, and policies. By redesigning the component collections of LECS, BJS will be able to provide detailed information about LEA performance that aligns these collections with an ongoing national debate about the need for new measures and metrics for law enforcement agencies.


In 2016, BJS and their data collection agent, RTI International, will be administering the first supplement to the LEMAS, 2016 Body-Worn Camera Supplement, and the LEMAS core. For more information on these collections, visit:

Beginning in 2017, BJS will and RTI International will administer the Survey of Law Enforcement Personnel in Schools (SLEPS), a research effort regarding the role and presence of law enforcement officers in schools. For more information on SLEPS, visit:
