The UCR Program consists of four data collections: The National Incident-Based Reporting System (NIBRS), the Summary Reporting System (SRS), the Law Enforcement Officers Killed and Assaulted (LEOKA) Program, and the Hate Crime Statistics Program. The UCR Program publishes annual reports for each of these data collections and a preliminary semiannual report of summary data each winter, as well as special compilations such as Cargo Theft Report, Human Trafficking, and NIBRS topical studies. In addition to the four major data collections, the UCR Program will manage the new National Use-of-Force Data Collection. And the FBI's interactive Crime Data Explorer tool serves as the digital front door for UCR data, enabling law enforcement and the general public to more easily use and understand the massive amounts of UCR data currently collected.
