The data within only represent 2019 and prior. As of January 2020, Mesa PD transitioned crime reporting to the FBI Unified Crime Reporting (UCR) Program from the Summary Reporting System (SRS) format to the new National Incident-Based Reporting System (NIBRS) format.
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.
