About this app
Our St. Louis Crime Tracker offers you a comprehensive look at crime around the St. Louis region.
We launched the first version of the app in August 2016, focusing on St. Louis city and its neighborhoods. In 2018, we expanded the app to include St. Louis County, with its array of more than 50 separate police departments.
On the front page, you will find a long-term trends chart, showing combined crime totals for the county and city since 2005.
Inside the app, the county and the city each have separate pages with maps showing year-over-year crime change. Clicking any neighborhood or jurisdiction will take you to a detailed report page with statistics and trends for that jurisdiction.
Important things to know
This app includes only the more serious "Part I" crimes, based on FBI Uniform Crime Reporting standards. Part I offenses include:
- murder and nonnegligent homicide
- aggravated assault
- motor vehicle theft
- This data reflects only reported crimes. Not all crimes are reported to the police.
- We update the Crime Tracker when we receive new data from our sources, usually monthly.
