Higher scores indicate safer modeled conditions. Scored areas are Census block groups, not a coverage percentage.
Each ZIP estimate is population weighted. The county score uses a separate national ranking, so it should not be read as the average of this table.

One county-wide number can't describe St. Mary's County. This page starts broad, then points you to the block groups, ZIP profiles, and address-centered views where the local differences actually show.
CrimeScore is modeled neighborhood safety context, not an official agency crime-rate report. Use it for comparison, API workflows, and map exploration, not as a guarantee about a specific person, home, or future event.
How to read the map
Each colored polygon is a Census block group, typically 600 to 3,000 residents. Greener regions score safer, and 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.
About the score
The county score provides national county-level context. ZIP estimates and local map scores summarize different geographic areas. These are modeled estimates, not official crime rates, causal explanations, or individual predictions. Prohibited high-impact uses remain out of scope.
