National Incident-Based Reporting System (NIBRS) Statistics

The National Incident-Based Reporting System (NIBRS), implemented to improve the overall quality of crime data collected by law enforcement, captures details on each single crime incident—as well as on separate offenses within the same incident—including information on victims, known offenders, relationships between victims and offenders, arrestees, and property involved in the crimes.

Unlike data reported through UCR’s traditional Summary System—an aggregate monthly tally of crimes— NIBRS data goes much deeper because of its ability to provide circumstances and context for crimes. It includes all offenses within a single incident and additional aspects about each event, like location, time of day, and whether the incident was cleared. More information about crime data reported under NIBRS can be found within the FBI’s National Incident-Based Reporting System (NIBRS) User Manual.

Ultimately, NIBRS will improve the detail and overall quality of crime data, which will help law enforcement and communities around the country use resources more strategically and effectively.
