01What the data says — and does not say
This page separates the checked GeoNames row for Osasco—728,615, America/Sao_Paulo, 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.
02This city's dataset fingerprint
The source row behind Osasco is GeoNames ID 3455775. Its recorded administrative path is Osasco → Sao Paulo → Brazil, and GeoNames classifies the place as a populated place. Osasco 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 2026-07-17; 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, Osasco ranks 757 by recorded population. Inside the 48 selected Brazil entries it ranks 26; inside the 198 entries in its broad region it ranks 112. Its 728,615 population value is 0.96 times the 758,563 median for the country cohort and 0.89 times the 816,326 regional median. Osasco sits in the lower half of this atlas's selected Brazil entries. Osasco'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.

Osasco's nearest-coordinate gap falls between the tightest tenth and quarter of the atlas. 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 3455775, the coordinate pair 23.5325 / 46.7917, country rank 26 of 48, and neighbor GeoNames 3448439 at 15.945 km bind Osasco to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Osasco's reference point is 23.5325° south and 46.7917° west. The IANA identifier America/Sao_Paulo is shared by 30 city rows in this catalog, while the GeoNames class PPL is shared by 243 rows. Osasco's row carries both second- and first-order administrative labels. Osasco's point falls in the lower-latitude coordinate band used by this atlas's row checks. Osasco's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Osasco, so the profile preserves that missing value instead of guessing terrain. Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
