NIBRS (National Incident-Based Reporting System)
NIBRS is an incident-based reporting system that collects data on each crime occurrence. The NIBRS program collects data on 22 primary offense categories, referred to as Group A offenses, and collects arrest data only on 11 additional offenses, referred to as Group B offenses. For each reported offense within the Group A category, incident, victim, property, offender, and arrestee information is collected. Full participation in the NIBRS program provides law enforcement agencies with a common denominator to link with other law enforcement agencies. It also provides extensive crime-specific information, which can further assist in the identification of common crime problems or trends. NIBRS data has the capability of providing information on numerous offenses including weapons violations, drug-related offenses, hate crimes, domestic violence, abuse of the elderly, gang-related crimes, and alcohol-related crimes.
