01What the data says — and does not say
This page separates the checked GeoNames row for Montevideo—1,270,737, America/Montevideo, 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: capital and largest city of Uruguay.
02This city's dataset fingerprint
The source row behind Montevideo is GeoNames ID 3441575. Its recorded administrative path is Municipio B → Montevideo Department → Uruguay, and GeoNames classifies the place as a capital of a political entity. Montevideo 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 2026-02-23; 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, Montevideo ranks 403 by recorded population. Inside the 1 selected Uruguay entries it ranks 1; inside the 198 entries in its broad region it ranks 56. Its 1,270,737 population value is 1.00 times the 1,270,737 median for the country cohort and 1.56 times the 816,326 regional median. Montevideo is rank 1 among the 1 selected Uruguay entries, so a percentage band would overstate this small cohort. Montevideo'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.
Montevideo's three nearest other atlas coordinates are Buenos Aires at 202.561 km with 2,891,082 recorded people; Mar del Plata at 365.463 km with 593,337 recorded people; Rosario at 464.682 km with 948,312 recorded people. The closest-to-farthest distance spread is 262.121 km. Compared with Buenos Aires, Montevideo's recorded population is 0.44 times as large. Against Montevideo, Buenos Aires follows Buenos Aires F.D. → Argentina in the source. Its point has higher latitude and lower longitude; it belongs to the selected Argentina cohort rather than Uruguay, uses America/Argentina/Buenos_Aires instead of America/Montevideo, and carries the same capital of a political entity class. Its recorded population is above Montevideo's. Against Montevideo, Mar del Plata follows Partido de General Pueyrredon → Buenos Aires → Argentina in the source. Its point has lower latitude and lower longitude; it belongs to the selected Argentina cohort rather than Uruguay, uses America/Argentina/Buenos_Aires instead of America/Montevideo, and carries second-order administrative seat rather than capital of a political entity. Its recorded population is below Montevideo's. Against Montevideo, Rosario follows Rosario Department → Santa Fe → Argentina in the source. Its point has higher latitude and lower longitude; it belongs to the selected Argentina cohort rather than Uruguay, uses America/Argentina/Cordoba instead of America/Montevideo, and carries second-order administrative seat rather than capital of a political entity. Its recorded population is below Montevideo's. Its nearest-neighbor distance ranks 1,003 of 1,206 from shortest to longest in the same snapshot. Montevideo's nearest-coordinate gap belongs to the wider half 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 3441575, the coordinate pair 34.9033 / 56.1882, country rank 1 of 1, and neighbor GeoNames 3435910 at 202.561 km bind Montevideo to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Montevideo's reference point is 34.9033° south and 56.1882° west. The IANA identifier America/Montevideo is shared by 1 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. Montevideo's row carries both second- and first-order administrative labels. Montevideo's point falls in the middle-latitude coordinate band used by this atlas's row checks. Montevideo's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Montevideo, 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.
