01What the data says — and does not say
This page separates the checked GeoNames row for Mexico City—12,294,193, America/Mexico_City, 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 Mexico.
02This city's dataset fingerprint
The source row behind Mexico City is GeoNames ID 3530597. Its recorded administrative path is Mexico City → Mexico, and GeoNames classifies the place as a capital of a political entity. Mexico City 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 2024-03-26; 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, Mexico City ranks 13 by recorded population. Inside the 39 selected Mexico entries it ranks 1; inside the 198 entries in its broad region it ranks 2. Its 12,294,193 population value is 15.21 times the 808,416 median for the country cohort and 15.06 times the 816,326 regional median. Mexico City falls inside the leading tenth of this atlas's Mexico population cohort. Mexico City'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.

Mexico City's nearest-coordinate gap belongs to the tightest tenth 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 3530597, the coordinate pair 19.4285 / 99.1277, country rank 1 of 39, and neighbor GeoNames 3827409 at 2.674 km bind Mexico City to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Mexico City's reference point is 19.4285° north and 99.1277° west. The IANA identifier America/Mexico_City is shared by 22 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. Mexico City's row carries a first-order administrative label but no second-order label. Mexico City's point falls in the lower-latitude coordinate band used by this atlas's row checks. Mexico City's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Mexico City, 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.
