01What the data says — and does not say
This page separates the checked GeoNames row for Niterói—515,317, 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 Niterói is GeoNames ID 3456283. Its recorded administrative path is Niteroi → Rio de Janeiro → Brazil, and GeoNames classifies the place as a populated place. Niterói 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 2026-07-15; 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, Niterói ranks 1,105 by recorded population. Inside the 48 selected Brazil entries it ranks 43; inside the 198 entries in its broad region it ranks 181. Its 515,317 population value is 0.68 times the 758,563 median for the country cohort and 0.63 times the 816,326 regional median. Niterói sits in the lower half of this atlas's selected Brazil entries. Niterói's recorded value is materially below the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Niterói's three nearest other atlas coordinates are Rio de Janeiro at 8.453 km with 6,747,815 recorded people; Duque de Caxias at 23.934 km with 866,347 recorded people; Belford Roxo at 33.088 km with 518,384 recorded people. The closest-to-farthest distance spread is 24.635 km. Compared with Rio de Janeiro, Niterói's recorded population is 0.08 times as large. Against Niterói, Rio de Janeiro follows Rio de Janeiro → Brazil in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Brazil cohort, uses the shared America/Sao_Paulo identifier, and carries first-order administrative seat rather than populated place. Its recorded population is above Niterói's. Against Niterói, Duque de Caxias follows Duque De Caxias → Rio de Janeiro → Brazil in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Brazil cohort, uses the shared America/Sao_Paulo identifier, and carries the same populated place class. Its recorded population is above Niterói's. Against Niterói, Belford Roxo follows Belford Roxo → Rio de Janeiro → Brazil in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Brazil cohort, uses the shared America/Sao_Paulo identifier, and carries the same populated place class. Its recorded population is above Niterói's. Its nearest-neighbor distance ranks 133 of 1,206 from shortest to longest in the same snapshot. Niterói'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 3456283, the coordinate pair 22.8833 / 43.1036, country rank 43 of 48, and neighbor GeoNames 3451190 at 8.453 km bind Niterói to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Niterói's reference point is 22.8833° south and 43.1036° 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. Niterói's row carries both second- and first-order administrative labels. Niterói's point falls in the lower-latitude coordinate band used by this atlas's row checks. Niterói's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Niterói, 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.
