Understanding NIBRS Figures

NIBRS compiles detailed reports on two types of offenses: Group “A” offenses and Group “B” offenses. The two groupings are based on the amount of reporting required for each. Both incidents and arrests are reported for Group “A” offenses, while only arrests are reported for Group “B” offenses. The following criteria is used to determine whether a crime should be designated as a Group “A” offense: 1. The seriousness or significance of the offense. 2. The frequency or volume of its occurrence. 3. The prevalence of the offense nationwide. 4. The probability of the offense being brought to law enforcement’s attention. 5. The likelihood that law enforcement is the best channel for collecting data regarding the offense. 6. The burden placed on law enforcement in collecting data on the offense. 7. The national statistical validity and usefulness of the collected data. 8. The national UCR Program’s responsibility to make crime data available not only to law enforcement but to others having a legitimate interest in it.

Group “A” offenses are categorized into one of the three following categories: 1) Crimes Against Persons; 2) Crimes Against Property; 3) Crimes Against Society.

1) Crimes Against Persons = Scores one offense for each victim 2) Crimes Against Property = Scores one offense for each distinct operation

(except Motor Vehicle Theft / one offense is counted per stolen vehicle)

3) Crime Against Society = Scores one offense for each violation

Significant Methodology and Definition Differences

A significant difference between NIBRS and UCR Traditional Summary Reporting is that for Crimes Against Persons, NIBRS counts the number of victims, while UCR counts the number of incidents. Con- sequentially, NIBRS figures tend to show more Crimes Against Persons than UCR figures. In addition, the definitions for Part 1 offenses used in Summary Reporting are different than the offense definitions used by the NIBRS.
