The UCR Program's primary objective is to generate reliable information for use in law enforcement administration, operation, and management; over the years, however, the data have become one of the country’s leading social indicators. The program has been the starting place for law enforcement executives, students of criminal justice, researchers, members of the media, and the public at large seeking information on crime in the nation. The program was conceived in 1929 by the International Association of Chiefs of Police to meet the need for reliable uniform crime statistics for the nation. In 1930, the FBI was tasked with collecting, publishing, and archiving those statistics.
Today, four annual publications are produced from data received from more than 18,000 city, university and college, county, state, tribal, and federal law enforcement agencies voluntarily participating in the program. The crime data are submitted either through a state UCR program or directly to the FBI's UCR Program.
Detailed, incident-based data is what the National Incident-Based Reporting System brings to the UCR table as it is set to become the UCR data standard by January 1, 2021. The NIBRS-only data collection will provide more detailed, richer data on more offenses than is currently available through summary data.
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.
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 will be able to 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.
The FBI’s Crime Data Explorer (CDE) is the digital front door for UCR data. The interactive online tool enables law enforcement and the general 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. As the CDE expands to provide greater access to crime trends, bulk datasets, and agency-level data, the UCR Program plans to increase the frequency of data releases with the tool.
NOTE: UCR data is now released quarterly on the CDE.
