Source identity and administrative path
The source row behind Nha Trang is GeoNames ID 1572151. Its recorded administrative path is Thanh Pho Nha Trang → Khanh Hoa → Vietnam, and GeoNames classifies the place as a first-order administrative seat. Nha Trang 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, Nha Trang ranks 961 by recorded population. Inside the 13 selected Vietnam entries it ranks 11; inside the 632 entries in its broad region it ranks 518. Its 579,000 population value is 0.46 times the 1,272,235 median for the country cohort and 0.57 times the 1,008,426 regional median. Nha Trang sits in the lower half of this atlas's selected Vietnam entries. Nha Trang'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
Nha Trang's three nearest other atlas coordinates are Qui Nhon at 170.315 km with 519,208 recorded people; Biên Hòa at 295.885 km with 1,272,235 recorded people; Thủ Đức at 306.176 km with 524,670 recorded people. The closest-to-farthest distance spread is 135.861 km. Compared with Qui Nhon, Nha Trang's recorded population is 1.12 times as large. Against Nha Trang, Qui Nhon follows Phu Cat District → Gia Lai → Vietnam in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Vietnam cohort, uses the shared Asia/Ho_Chi_Minh identifier, and carries the same first-order administrative seat class. Its recorded population is below Nha Trang's. Against Nha Trang, Biên Hòa follows Thanh Pho Bien Hoa → Dong Nai → Vietnam in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Vietnam cohort, uses the shared Asia/Ho_Chi_Minh identifier, and carries the same first-order administrative seat class. Its recorded population is above Nha Trang's. Against Nha Trang, Thủ Đức follows Quan Thu GJuc → Ho Chi Minh City (HCMC) → Vietnam in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Vietnam cohort, uses the shared Asia/Ho_Chi_Minh identifier, and carries second-order administrative seat rather than first-order administrative seat. Its recorded population is below Nha Trang's. Its nearest-neighbor distance ranks 930 of 1,206 from shortest to longest in the same snapshot. Nha Trang'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 1572151, the coordinate pair 12.2451 / 109.1943, country rank 11 of 13, and neighbor GeoNames 1568574 at 170.315 km bind Nha Trang 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
Nha Trang's reference point is 12.2451° north and 109.1943° east. The IANA identifier Asia/Ho_Chi_Minh is shared by 8 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Nha Trang's row carries both second- and first-order administrative labels. Nha Trang's point falls in the near-equatorial coordinate band used by this atlas's row checks. Nha Trang's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Nha Trang, 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.
