The Law Enforcement Management and Administrative Statistics (LEMAS) survey has historically been conducted by the Bureau of Justice Statistics approximately every four years. The core survey is the most systematic and comprehensive source of national data on law enforcement. Approximately 3,500 agencies are randomly selected to participate in this survey. Agencies with more than 100 full-time sworn personnel are always selected into the sample.
