In response to law enforcement’s need for more flexible, in-depth data, the Uniform Crime Reports (UCR) Program formulated the National Incident-Based Reporting System (NIBRS). NIBRS presents comprehensive, detailed information about crime incidents to law enforcement, researchers, governmental planners, students of crime, and the general public. A NIBRS fact sheet, written by the FBI can be found at http://www.fbi.gov/about-us/cjis/ucr/frequently-asked-questions/nibrs_faqs.

This data set contains Group A Offenses for the entire City. Please visit http://www.fbi.gov/about-us/cjis/ucr/nibrs to learn more about NIBRS. The "Data Collection Guidelines" outlines how this data is structured and provides the exact definitions and methodology behind this data set.
