NIBRS is the FBI's National Incident-Based Reporting System, collecting detailed crime data from law enforcement agencies. Incidents is the number of crimes reported in a quarter. Crime rates are calculated per 100,000 people using Participated Population, the population covered by agencies reporting NIBRS data.
