How do NIBRS and UCR differ in crime data collection?

• A. UCR provides summary data; NIBRS collects detailed incident-based data, including characteristics of offenders and victims.
• B. NIBRS collects arrest data only.
• C. UCR provides detailed incident-based data; NIBRS provides summary data.
• D. NIBRS is used only for traffic offenses.

Answer: (A)

Understanding how crime data are collected helps you see why these systems differ. NIBRS uses an incident-based approach, recording details for each crime incident—offenses involved, information about victims and offenders, location, time, weapons, arrestees, and more. This level of detail and the ability to capture multiple offenses within the same incident provide a richer, more nuanced picture of crime patterns and relationships. UCR, in its traditional form, provides summary data. It aggregates counts of offenses known to police by offense type and jurisdiction, often using a hierarchy rule that records only the most serious offense in a given incident. That means the data show total counts but not the full sequence of offenses, nor the characteristics of victims and offenders. So the best description is that UCR offers summary data, while NIBRS collects detailed incident-based data, including information about offenders and victims. The other statements misstate what each system collects: NIBRS is not limited to arrests; UCR is not detailed incident-based data; NIBRS is not a summary system; and NIBRS is not used only for traffic offenses.
