The Uniform Crime Reporting (UCR) Program collects statistics on the number of offenses known to City of Mesa Police Department. In Part I, the UCR indexes reported incidents of crimes that are broken into two categories: violent and property crimes. Aggravated assault, forcible rape, murder, and robbery are classified as violent, while arson, burglary, larceny-theft, and motor vehicle theft are classified as property crimes.

As of January 1, 2021, the National Incident-Based Reporting System (NIBRS) became the national crime data collection program.

NIBRS was implemented to improve the overall quality of crime data collected by law enforcement, by capturing details on each single crime incident, as well as on separate offenses within the same incident. The historic Summary Reporting System (SRS) data collection, which collects more limited information than the more robust NIBRS, was phased out to make Uniform Crime Reporting (UCR) a NIBRS-only data collection.

A case is considered “cleared” when it is cleared by arrest or exceptional means. Cases credited as “cleared” in a given month or year may have been opened in a previous month or year. For this reason, the clearance rate for a given period may be above 100%.
