National Incident-Based Reporting System Law and Legal Definition

The National Incident Based Reporting System (NIBRS) is an incident-based reporting system used by the U.S. law enforcement agencies to report data relating to crimes. The NIBRS is also used to collect data on crimes.

A variety of data are collected about each crime incident that is noticed by a law enforcement official. The collected data may include information such as: the nature of the offense, types of offenses in the incident, characteristics of the victim and offender, types and value of property stolen and recovered, and characteristics of persons arrested in connection with a crime incident. Such incident-based data provide a large amount and useful information about crime. The information is also organized in complex ways, reflecting the many different aspects of a crime incident.

The NIBRS is a city, county, state, and federal law enforcement program. Local, state and federal agencies generate NIBRS data from their records management systems. NIBRS offers law enforcement and the academic community more comprehensive data for management, training, planning, and research.
