The Uniform Crime Reporting (UCR) Program generates reliable statistics for use in law enforcement. It also provides information for students of criminal justice, researchers, the media, and the public. The program has been providing crime statistics since 1930.
The UCR Program includes data from more than 18,000 city, university and college, county, state, tribal, and federal law enforcement agencies. Agencies participate voluntarily and submit their crime data either through a state UCR program or directly to the FBI's UCR Program.
Latest Releases
The latest UCR releases are available on the FBI's Crime Data Explorer.
Historical publications (through 2019) are on the UCR Publications page.
National Incident-Based Reporting System
The National Incident-Based Reporting System, or NIBRS, implemented to improve the overall quality of crime data collected by law enforcement. It captures details on each single crime incident—as well as on separate offenses within the same incident. The historic Summary Reporting System (SRS) data collection, which collects more limited information than the more robust NIBRS, was phased out to make UCR a NIBRS-only data collection as of Jan. 1, 2021.
Hate Crime Statistics
The Hate Crime Statistics Program provides information on crimes motivated by offenders’ bias against race, gender, gender identity, religion, disability, sexual orientation, and ethnicity. These data are also collected via NIBRS.
Law Enforcement Officers Killed and Assaulted
The Law Enforcement Officers Killed and Assaulted (LEOKA) Program offers information about officers who were feloniously or accidentally killed or assaulted while performing their duties. The information is published and used to help agencies develop polices to improve officer safety.
The National Use-of-Force Data Collection
Transparency. Accountability. Trust.
The law enforcement community, in partnership with the FBI, is working to improve the way the nation collects, analyzes, and uses crime statistics about law enforcement’s use of force. The collection and reporting of use-of-force data will include any use of force that results in the death or serious bodily injury of a person, as well as when a law enforcement officer discharges a firearm at or in the direction of a person.
With the National Use-of-Force Data Collection, data users can view use-of-force incidents involving law enforcement from a nationwide perspective. The goal of the resulting statistics is not to offer insight into single use-of-force incidents but to provide an aggregate view of the incidents reported and the circumstances, subjects, and officers involved.
Crime Data Explorer
Explore UCR
The FBI’s Crime Data Explorer (CDE) is the digital front door for UCR data. The interactive online tool enables law enforcement and the public to more easily use and understand the massive amounts of UCR data currently collected. With it, users can view charts and graphs that break down data in a variety of ways.
NOTE: UCR data is now released quarterly on the CDE.
