Law Enforcement Agency Reported Crime Analysis Tool (LEARCAT)

NCJ Number
Date Published
October 2022

The Bureau of Justice Statistics (BJS) established the Law Enforcement Agency Reported Crime Analysis Tool (LEARCAT) to provide access to incident-based data on crimes recorded by law enforcement. LEARCAT uses data from the FBI’s National Incident-Based Reporting System (NIBRS), as well as contextual information from other federal data sources, such as the U.S. Census Bureau.  

LEARCAT enables users to—

  • examine NIBRS data at multiple levels of geography, including the state, county, and agency levels
  • produce custom views of the NIBRS data that provide information on various attributes of crime
  • produce custom data sets for analysis
  • generate univariate statistics and perform basic cross-tabulation analyses, among other functions.

LEARCAT contains NIBRS data from 2016 to 2021. BJS will enhance or expand data within the tool, based on the availability of data and resources.
