Source identity and administrative path
The source row behind Saltillo is GeoNames ID 3988086. Its recorded administrative path is Saltillo → Coahuila → Mexico, and GeoNames classifies the place as a first-order administrative seat. Saltillo 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.
Population position inside fixed cohorts
Within the fixed 1,206-record atlas, Saltillo ranks 777 by recorded population. Inside the 39 selected Mexico entries it ranks 25; inside the 198 entries in its broad region it ranks 117. Its 709,671 population value is 0.88 times the 808,416 median for the country cohort and 0.87 times the 816,326 regional median. Saltillo sits in the lower half of this atlas's selected Mexico entries. Saltillo'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.
Nearest-reference pattern
Saltillo's three nearest other atlas coordinates are Monterrey at 72.397 km with 1,135,512 recorded people; Guadalupe at 77.475 km with 673,616 recorded people; Torreón at 245.198 km with 735,340 recorded people. The closest-to-farthest distance spread is 172.801 km. Compared with Monterrey, Saltillo's recorded population is 0.62 times as large. Against Saltillo, Monterrey follows Monterrey → Nuevo Leon → Mexico in the source. Its point has higher latitude and higher 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 above Saltillo's. Against Saltillo, Guadalupe follows Guadalupe → Nuevo Leon → Mexico in the source. Its point has higher 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 Saltillo's. Against Saltillo, Torreón follows Torreon → Coahuila → Mexico in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Mexico cohort, uses the shared America/Monterrey identifier, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is above Saltillo's. Its nearest-neighbor distance ranks 571 of 1,206 from shortest to longest in the same snapshot. Saltillo's nearest-coordinate gap sits in the second quarter 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 3988086, the coordinate pair 25.4260 / 100.9796, country rank 25 of 39, and neighbor GeoNames 3995465 at 72.397 km bind Saltillo 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
Saltillo's reference point is 25.4260° north and 100.9796° 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. Saltillo's row carries both second- and first-order administrative labels. Saltillo's point falls in the lower-latitude coordinate band used by this atlas's row checks. Saltillo's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Saltillo, 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.
