01What the data says — and does not say
This page separates the checked GeoNames row for San Francisco—827,526, America/Los_Angeles, and source coordinates—from live travel claims. Those fields identify and compare the record; they do not prove current transport, accessibility, census totals, or a City Atlas Club visit.
Wikidata's localized description: consolidated city and county in California, United States.
02This city's dataset fingerprint
The source row behind San Francisco is GeoNames ID 5391959. Its recorded administrative path is City and County of San Francisco → California → United States, and GeoNames classifies the place as a second-order administrative seat. San Francisco occurs once as a primary city label in this atlas sample; the numeric ID remains the durable source key if names change. The city row itself was updated 2025-07-22; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Within the fixed 1,206-record atlas, San Francisco ranks 676 by recorded population. Inside the 43 selected United States entries it ranks 21; inside the 198 entries in its broad region it ranks 98.

San Francisco sits in the second quarter of this atlas's United States population cohort. San Francisco's recorded value stays within one quarter of the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.

San Francisco's nearest-coordinate gap sits in the second quarter of atlas distances. This pattern can reveal whether other catalog references are geographically close, but it cannot establish whether a border crossing is possible or practical, or whether rail, road, fare, or journey-time connections exist. Read as one record signature, GeoNames 5391959, the coordinate pair 37.7749 / 122.4194, country rank 21 of 43, and neighbor GeoNames 5392171 at 66.953 km bind San Francisco to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
San Francisco's reference point is 37.7749° north and 122.4194° west. The IANA identifier America/Los_Angeles is shared by 9 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. San Francisco's row carries both second- and first-order administrative labels. San Francisco's point falls in the middle-latitude coordinate band used by this atlas's row checks. San Francisco's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames records San Francisco at 16 metres above sea level, a single reference value rather than a description of slopes across the city. Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
