How we count
From the open Overture Maps business listings (release 2026-10-21.0), within San Francisco’s boundary, counted in October 2026. Listings data, not a census: a few may have closed or moved, and a business filed under another category is not included. Population is the city’s own figure from the same release’s boundaries.
