Group A offense

A Group A offense receives detailed NIBRS incident reporting. Learn why Group A differs from felony status, SRS categories, and arrest counts.

A Group A offense is an offense classification for which NIBRS collects detailed incident information. The group identifies a reporting structure, including information about the offense and relevant people or property. It is not simply another name for a felony, a violent crime, or an offense that resulted in arrest.

Detail beyond an arrest

A Group A incident report can include administrative, offense, property, victim, offender, and arrestee information, as applicable. An arrestee record is not required merely to establish that a Group A offense was reported. An agency can record an incident while the offender remains unknown. FBI NIBRS manual, report structure

Group A covers a range of person, property, and society offenses. The NIBRS grouping is separate from state distinctions such as felony and misdemeanor. Statistical offense definitions are designed to organize differing state laws into reporting categories, not to replace those laws. NCSBI classification guidance

A public dashboard may include only Group A data. North Carolina's Justice Data Portal expressly identifies that limit for its NIBRS dashboards. Its displayed crime total should therefore be understood within that scope rather than as every crime category an agency handles. NC portal methodology

Example

Hypothetical example: An agency records a burglary with property information and no known suspect. The incident enters its Group A reporting stream. Later, an arrest is linked to the incident.

The original incident was reportable before the arrest. Counting only records that contain an arrestee would omit it from the earlier period and distort an offense total. The later arrest is additional information about the case, not a second burglary merely because a new segment was submitted.

Common confusion

Group A and SRS Part I are different classification schemes. They do not have identical coverage. A table using one should not silently adopt totals or definitions from the other.

Group A also differs from a count of incidents. One incident can include several Group A offense types, and a victim-based count can differ again. The group tells readers which reporting class applies, not the counting unit used by every publication.

Checking the applicable version

Use the offense list and manual for the relevant data year. Classification systems can be revised, and a fixed category count becomes misleading when presented without a version. For comparisons, verify consistent included codes, agency participation, and whether revisions or newly reportable offenses affect the series.
