Methodology
Neighbours count.
Crime does not stop at a ZIP line, so a ZIP's grade also reflects the ZIPs that touch it. Lower-scoring neighbours pull a target down; higher-scoring ones pull it up. Pick any ZIP to see who it borders and which way they pull.

5 of 8 touching ZIPs score lower than Federal Hill, 3 score higher. Lower neighbours pull the target down: a ZIP surrounded by calmer areas grades lower than its own incidents alone would suggest.
Illustration: at a 25% neighbour weight the target would read 99.05 instead of 99.22. The published model applies its own weighting; ZIPs outside this 30-ZIP map that touch 21230 are not shown.

The CrimeScore scale
Where a ZIP falls among all US ZIP codes, by crime intensity · September 2026
Zoomed to the 93rd–100th percentile. Every one of these Baltimore ZIPs lands here, in the top 5% of the country.
Percentile is the share of US ZIP codes with lower crime intensity. A ZIP at the 99th percentile has more crime than 99% of the country. Levels are fixed cutoffs, so a ZIP's level changes only when its data does.

Questions people ask, answered the same way here and by your assistant.
- What is CrimeScore?
- CrimeScore turns police incident reports from SpotCrime into a monthly crime score for US ZIP codes (ZCTAs) and counties. Each score comes with a national percentile, a national rank, and a state rank, and is exposed to AI assistants through a Model Context Protocol (MCP) connector at mcp.crimescore.info.
- How do I read the score?
- The percentile is the share of US ZIP codes with lower crime intensity, so a ZIP at the 99th percentile has more reported crime than 99% of the country. A higher percentile and a lower rank number both mean more crime; rank #1 is the highest-crime ZIP nationally. Percentiles map to six fixed levels: Low (under 25), Below Average (25 to 50), Above Average (50 to 75), High (75 to 90), Very High (90 to 99), and Extreme (99 and above).
- Where does the data come from?
- From SpotCrime, which has collected and geocoded police incident reports across the United States since 2007, a dataset of more than 60 million incidents. CrimeScore is a SpotCrime product.
- How often are scores updated?
- Monthly. Every score shows the snapshot month it was published for, and ZIP pages list the recent months so you can see the trend.
- Which areas are covered?
- Scores exist for more than 13,000 US ZIP codes and hundreds of counties, and coverage grows every month as more police data qualifies. Every published score is free to look up on this site by ZIP code or county. An API token is only needed for programmatic or AI-assistant access. If an area returns "not found", we do not yet have police data for it, which is not the same as it being safe.
- How do I connect CrimeScore to Claude or another AI assistant?
- Register the MCP connector once with your bearer token. In Claude Code: claude mcp add --transport http crimescore https://mcp.crimescore.info/mcp --header "Authorization: Bearer YOUR_TOKEN". Any MCP-compatible assistant can use the same HTTP endpoint. Then ask in plain English, for example "What is the crime score for ZIP 21201?"
- How do I get a token?
- Request one at crimescore.info/request or email feedback@spotcrime.com. Demo tokens cover the Baltimore preview ZIPs; full-access tokens cover every published ZIP and county.
- Who is CrimeScore for?
- Teams that need a consistent, explainable crime signal inside automated decisions: real estate underwriting and site selection, logistics and fleet routing, insurance modeling, corporate travel security, and developers building AI assistants that answer neighborhood questions.
