National Incident Based Reporting System

Overview
The National Incident Based Reporting System (NIBRS) is an incident-based reporting system for crimes known to the police. For each crime incident coming to the attention of law enforcement, a variety of data are collected about the incident. These data include the nature and types of specific offenses in the incident, characteristics of the victim(s) and offender(s), types and value of property stolen and recovered, and characteristics of persons arrested in connection with a crime incident.

Incident-based data provide an extremely large amount of information about crime. The information is also organized in complex ways, reflecting the many different aspects of a crime incident. This website provides a Resource Guide for learning about, accessing and using NIBRS data.
