Crime statistics for San Francisco (ZIP 94112) are sourced from a city open-data portal via the Socrata SODA API. Each incident coordinate is assigned at most once using a U.S. Census Bureau 2020 ZIP Code Tabulation Area (ZCTA) polygon. ZCTAs are generalized representations—not official USPS ZIP service-area boundaries—and incidents outside a covered ZCTA are excluded. Reported incidents are grouped by month and category; refresh timing depends on the source portal.

The crime score of 45/100 uses the best available city, agency, county, or state-remainder tier and its applicable benchmark. A higher score represents a lower reported rate under that tier; it is not a guarantee of safety.
