What Is NIBRS?
Multiple Data Segment Per Incident Report
A segment in NIBRS is a set of related data elements that describe an aspect of a reported crime incident.
A complete Group "A" Offense Incident Report comprises six data segments: administrative, offense, property, victim, offender, and arrestee. Each Group "A" Offense Incident Report must include the administrative, offense, victim, and offender data segments at the time of submission. The submission of the property segment and the arrestee segment are conditioned upon the type of offense and the occasion of an arrest, respectively.
A Group "B" Offense Arrest Report consists only of one data segment, which is the arrestee segment; the other incident-level data are not collected for this group of offenses.
