Incidents based on initial police reports taken by officers when responding to calls for service. Data is modified for public use. Address and Location are not exact locations of incidents and have been rounded to nearest hundred block. Lat/Long are approximations only based on rounded hundred block.

The City of Mesa does not disclose information that is inflammatory in nature that impacts our citizens. Crimes reported in this data set have not been adjudicated in a court of law for final determination.

Although sensitive crimes are included, the approximate address are NOT included. Therefore aggregate totals of crimes are accurate, without providing sensitive information. Addresses are not included for: sexual abuse, sexual assault, suicide, incest, molestation of a child or homicide.

Similar information is also provided through the Communitycrimemap.com website, a 3rd party service that visually reviews crime data for Mesa and outlining areas.

Some of the data fields provided are used to report to the Federal Bureau of Investigation. For a listing of data fields and description please see their UCR Program Data Collections page. Alternatively, please see the Bureau of Justice Statistics NIBRS website for a listing of data fields.

Police incidents reported as crimes against person or property. See "Criminal Activity" PDF in the attachments section for list of the 15 offenses included. Filtered view to include only if the incident involved one or more of the 15 listed offenses.

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.
