Local search context
People comparing St. Louis County crime rates, maps, or neighborhood safety data usually need more than a single county-wide number. CrimeScore starts with the broad county page, then lets visitors inspect smaller map areas, ZIP pages, and address-centered views when they need more local context.
CrimeScore is modeled neighborhood safety context, not an official agency crime-rate report. Use it as location context for comparison, API workflows, and map exploration, not as a guarantee about a specific person, home, or future event.
Each colored polygon is a Census block group, typically 600 to 3,000 residents. Greener regions score safer; orange and red indicate lower modeled safety. Click any block group to see its score and grade. Create an account to review API plans for production use.
Scores in St. Louis County come from the same gradient-boosted ensemble we ship through the CrimeScore crime data API, crime score API, and embeddable crime map. Built from normalized national location signals and validated across geography. Protected attributes are excluded from scoring, and prohibited/high-impact uses are explicitly out of scope.
