01What the data says — and does not say
This page separates the checked GeoNames row for Monterrey—1,135,512, America/Monterrey, 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 of the State of Nuevo Leon, Mexico.
02This city's dataset fingerprint
The source row behind Monterrey is GeoNames ID 3995465. Its recorded administrative path is Monterrey → Nuevo Leon → Mexico, and GeoNames classifies the place as a first-order administrative seat. Monterrey 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 2026-04-14; 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, Monterrey ranks 476 by recorded population. Inside the 39 selected Mexico entries it ranks 13; inside the 198 entries in its broad region it ranks 65. Its 1,135,512 population value is 1.40 times the 808,416 median for the country cohort and 1.39 times the 816,326 regional median. Monterrey sits in the second quarter of this atlas's Mexico population cohort. Monterrey's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Monterrey's three nearest other atlas coordinates are Guadalupe at 5.889 km with 673,616 recorded people; Saltillo at 72.397 km with 709,671 recorded people; Reynosa at 208.052 km with 589,466 recorded people. The closest-to-farthest distance spread is 202.163 km. Compared with Guadalupe, Monterrey's recorded population is 1.69 times as large. Against Monterrey, Guadalupe follows Guadalupe → Nuevo Leon → Mexico in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Mexico cohort, uses the shared America/Monterrey identifier, and carries populated place rather than first-order administrative seat. Its recorded population is below Monterrey's. Against Monterrey, Saltillo follows Saltillo → Coahuila → Mexico in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Mexico cohort, uses the shared America/Monterrey identifier, and carries the same first-order administrative seat class. Its recorded population is below Monterrey's. Against Monterrey, Reynosa follows Reynosa → Tamaulipas → Mexico in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Mexico cohort, uses America/Matamoros instead of America/Monterrey, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Monterrey's. Its nearest-neighbor distance ranks 74 of 1,206 from shortest to longest in the same snapshot. Monterrey'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 3995465, the coordinate pair 25.6844 / 100.3172, country rank 13 of 39, and neighbor GeoNames 4005492 at 5.889 km bind Monterrey to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Monterrey's reference point is 25.6844° north and 100.3172° west. The IANA identifier America/Monterrey is shared by 6 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Monterrey's row carries both second- and first-order administrative labels. Monterrey's point falls in the lower-latitude coordinate band used by this atlas's row checks. Monterrey's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Monterrey, 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.
