01What the data says — and does not say
This page separates the checked GeoNames row for Buenos Aires—2,891,082, America/Argentina/Buenos_Aires, 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 Argentina.
02This city's dataset fingerprint
The source row behind Buenos Aires is GeoNames ID 3435910. Its recorded administrative path is Buenos Aires F.D. → Argentina, and GeoNames classifies the place as a capital of a political entity. Buenos Aires 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 2024-06-19; 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, Buenos Aires ranks 124 by recorded population. Inside the 6 selected Argentina entries it ranks 1; inside the 198 entries in its broad region it ranks 10. Its 2,891,082 population value is 3.75 times the 770,825 median for the country cohort and 3.54 times the 816,326 regional median. Buenos Aires is rank 1 among the 6 selected Argentina entries, so a percentage band would overstate this small cohort. Buenos Aires's recorded value reaches at least twice the country-cohort median in this snapshot. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.

Buenos Aires'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 3435910, the coordinate pair 34.6132 / 58.3772, country rank 1 of 6, and neighbor GeoNames 3441575 at 202.561 km bind Buenos Aires to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Buenos Aires's reference point is 34.6132° south and 58.3772° west. The IANA identifier America/Argentina/Buenos_Aires is shared by 2 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. Buenos Aires's row carries a first-order administrative label but no second-order label. Buenos Aires's point falls in the middle-latitude coordinate band used by this atlas's row checks. Buenos Aires's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Buenos Aires, 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.
