National Incident-Based Reporting System (NIBRS)

Created to improve the quantity and quality of crime data collected by law enforcement, the FBI UCR Program’s National Incident-Based Reporting System (NIBRS) captures more detailed information for each single crime occurrence than the traditional Summary Reporting System (SRS). The NIBRS identifies when and where crime takes place, what form it takes, and the characteristics of the victims and perpetrators.

Additional help using the system can be found at the Incident-Based Reporting Resource Center (IBRRC), which is supported by the Bureau of Justice Statistics (BJS) to provide comprehensive information on accessing and using incident-based reporting data for the analysis of crime and reporting of justice statistics. The Center facilitates the use of state incident-based reporting (IBR) systems and the NIBRS. The Center provides practical analytical information and tools to analysts working with incident-based data, and provides a forum where analysts can exchange information and ideas about using IBR data.
