The National Crime Statistics Exchange (NCS-X) Initiative, a Bureau of Justice Statistics Program, is pleased to release a report entitled Multiple Offense Incidents in the National Incident-Based Reporting System, which describes the characteristics of crime incidents recorded in the National Incident-Based Reporting System (NIBRS). The report focuses specifically on the crime incidents that involve more than one unique offense type to better understand the context and characteristics of these multiple offense incidents (MOIs) and their potential to impact an agency's crime statistics. The report also examines how the percentage and type of MOIs varies by agency size and population served. Key findings include that, of the 5.2 million incidents analyzed, approximately 12% of incidents involved multiple offenses and fewer than 1% of incidents involved multiple Part I offenses.
