Crime Index

The Crime Index reported in the FBI’s Uniform Crime Reporting (UCR) program is the most commonly used measure of crime and is a consistent sample that allows for national comparisons of rates per 1,000 population.

In 2018, the UCR program transitioned from its legacy data collection system to a newer UCR-Tech Refresh (UCR-TR) collection & publishing platform. The change in the computing platform may result in differences in UCR data from previous years, and caution should be used when analyzing data.  Differences may be due too technical and procedural reasons rather than increases or decreases in crime.
