Source identity and administrative path
The source row behind Reynosa is GeoNames ID 3520339. Its recorded administrative path is Reynosa → Tamaulipas → Mexico, and GeoNames classifies the place as a second-order administrative seat. Reynosa 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 2025-05-15; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Population position inside fixed cohorts
Within the fixed 1,206-record atlas, Reynosa ranks 951 by recorded population. Inside the 39 selected Mexico entries it ranks 32; inside the 198 entries in its broad region it ranks 153. Its 589,466 population value is 0.73 times the 808,416 median for the country cohort and 0.72 times the 816,326 regional median. Reynosa sits in the lower half of this atlas's selected Mexico entries. Reynosa'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.
Nearest-reference pattern
Reynosa's three nearest other atlas coordinates are Heroica Matamoros at 81.125 km with 510,739 recorded people; Guadalupe at 202.566 km with 673,616 recorded people; Monterrey at 208.052 km with 1,135,512 recorded people. The closest-to-farthest distance spread is 126.927 km. Compared with Heroica Matamoros, Reynosa's recorded population is 1.15 times as large. Against Reynosa, Heroica Matamoros follows Matamoros → Tamaulipas → Mexico in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Mexico cohort, uses the shared America/Matamoros identifier, and carries populated place rather than second-order administrative seat. Its recorded population is below Reynosa's. Against Reynosa, Guadalupe follows Guadalupe → Nuevo Leon → Mexico in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Mexico cohort, uses America/Monterrey instead of America/Matamoros, and carries populated place rather than second-order administrative seat. Its recorded population is above Reynosa's. Against Reynosa, Monterrey follows Monterrey → Nuevo Leon → Mexico in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Mexico cohort, uses America/Monterrey instead of America/Matamoros, and carries first-order administrative seat rather than second-order administrative seat. Its recorded population is above Reynosa's. Its nearest-neighbor distance ranks 619 of 1,206 from shortest to longest in the same snapshot. Reynosa'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 3520339, the coordinate pair 26.0801 / 98.2846, country rank 32 of 39, and neighbor GeoNames 3523466 at 81.125 km bind Reynosa to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Coordinate, time-zone and class cohorts
Reynosa's reference point is 26.0801° north and 98.2846° west. The IANA identifier America/Matamoros is shared by 2 city rows in this catalog, while the GeoNames class PPLA2 is shared by 341 rows. Reynosa's row carries both second- and first-order administrative labels. Reynosa's point falls in the lower-latitude coordinate band used by this atlas's row checks. Reynosa's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Reynosa, 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.
