UCR Publications
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 on cargo theft, human trafficking, and NIBRS topical studies.
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.
Crime Data Explorer (CDE)
Crime Data Explorer, an online interactive data tool, is the digital front door of the FBI’s Uniform Crime Reporting (UCR) Program. Law enforcement and the public can use CDE to easily access, view, and understand the massive amounts of UCR data collected and published by the FBI UCR Program.
UCR data is released quarterly on the CDE. Historical UCR publications (through 2019) are available below.
Crime in the United States
An annual publication for more than eight decades, the Crime in the United States report contains a compilation of the volume and rate of violent and property crime offenses for the nation and by state using Summary Reporting System data and summarized data from the National Incident-Based Reporting System (NIBRS). Data at the level of local law enforcement agencies are also provided for those contributors supplying 12 months of complete offense data. This report includes arrests, clearances, trends, and law enforcement employee data.
National Incident-Based Reporting System (NIBRS)
Implemented to improve the overall quantity and quality of crime data collected by law enforcement, NIBRS captures more detailed information on each single crime occurrence. NIBRS’ first annual compilation of published data covered calendar year 2011. NIBRS data has also been used to publish some specialized topical crime reports.
Law Enforcement Officers Killed and Assaulted (LEOKA)
An annual publication since 1972, the LEOKA report provides data on law enforcement officers who were feloniously killed, accidentally killed, and assaulted in the line of duty. This report includes summaries of incidents in which officers were feloniously killed in the line of duty. Similar summaries are included for select incidents in which victim officers were assaulted and injured with firearms or knives/other cutting instruments.
Hate Crime Statistics
Data on the number of incidents, offenses, victims, and offenders in reported crimes that were motivated in whole or in part by a bias are available in the annual Hate Crime Statistics publication. The types of bias motivations captured include those against the victim’s perceived race, gender identity, religion, disability, sexual orientation, or ethnicity/national origin as well as bias crimes committed by or directed toward juveniles.
National Use-of-Force Data Collection
National Use-of-Force Data Collection reports are available on the FBI's Crime Data Explorer.
