Source identity and administrative path
The source row behind Chiang Mai is GeoNames ID 1153671. Its recorded administrative path is Amphoe Mueang Chiang Mai → Chiang Mai → Thailand, and GeoNames classifies the place as a first-order administrative seat. Chiang Mai 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, Chiang Mai ranks 1,204 by recorded population. Inside the 2 selected Thailand entries it ranks 2; inside the 632 entries in its broad region it ranks 632. Its 127,240 population value is 0.05 times the 2,615,858 median for the country cohort and 0.13 times the 1,008,426 regional median. Chiang Mai is rank 2 among the 2 selected Thailand entries, so a percentage band would overstate this small cohort. Chiang Mai'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
Chiang Mai's three nearest other atlas coordinates are Nay Pyi Taw at 317.912 km with 925,000 recorded people; Yangon at 372.011 km with 4,477,638 recorded people; Hlaingthaya at 376.773 km with 687,867 recorded people. The closest-to-farthest distance spread is 58.861 km. Compared with Nay Pyi Taw, Chiang Mai's recorded population is 0.14 times as large. Against Chiang Mai, Nay Pyi Taw follows Nay Pyi Taw (South) → Nay Pyi Taw → Myanmar (Burma) in the source. Its point has higher latitude and lower longitude; it belongs to the selected Myanmar (Burma) cohort rather than Thailand, uses Asia/Yangon instead of Asia/Bangkok, and carries capital of a political entity rather than first-order administrative seat. Its recorded population is above Chiang Mai's. Against Chiang Mai, Yangon follows West Yangon District → Yangon → Myanmar (Burma) in the source. Its point has lower latitude and lower longitude; it belongs to the selected Myanmar (Burma) cohort rather than Thailand, uses Asia/Yangon instead of Asia/Bangkok, and carries the same first-order administrative seat class. Its recorded population is above Chiang Mai's. Against Chiang Mai, Hlaingthaya follows Yangon (North) → Yangon → Myanmar (Burma) in the source. Its point has lower latitude and lower longitude; it belongs to the selected Myanmar (Burma) cohort rather than Thailand, uses Asia/Yangon instead of Asia/Bangkok, and carries populated place rather than first-order administrative seat. Its recorded population is above Chiang Mai's. Its nearest-neighbor distance ranks 1,122 of 1,206 from shortest to longest in the same snapshot. Chiang Mai'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 1153671, the coordinate pair 18.7904 / 98.9847, country rank 2 of 2, and neighbor GeoNames 6611854 at 317.912 km bind Chiang Mai 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
Chiang Mai's reference point is 18.7904° north and 98.9847° east. The IANA identifier Asia/Bangkok is shared by 7 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Chiang Mai's row carries both second- and first-order administrative labels. Chiang Mai's point falls in the lower-latitude coordinate band used by this atlas's row checks. Chiang Mai's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Chiang Mai, 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.
