01What the data says — and does not say
This page separates the checked GeoNames row for Hanoi—8,053,663, Asia/Bangkok, 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 Vietnam.
02This city's dataset fingerprint
The source row behind Hanoi is GeoNames ID 1581130. Its recorded administrative path is Hanoi → Vietnam, and GeoNames classifies the place as a capital of a political entity. Hanoi 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 2026-05-07; 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, Hanoi ranks 33 by recorded population. Inside the 13 selected Vietnam entries it ranks 2; inside the 632 entries in its broad region it ranks 23. Its 8,053,663 population value is 6.33 times the 1,272,235 median for the country cohort and 7.99 times the 1,008,426 regional median. Hanoi falls inside the leading tenth of this atlas's Vietnam population cohort. Hanoi's recorded value reaches at least twice the country-cohort median in this snapshot. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Hanoi's three nearest other atlas coordinates are Haiphong at 89.253 km with 2,625,200 recorded people; Thanh Hóa at 136.379 km with 850,000 recorded people; Vinh at 261.897 km with 790,000 recorded people. The closest-to-farthest distance spread is 172.644 km. Compared with Haiphong, Hanoi's recorded population is 3.07 times as large. Against Hanoi, Haiphong follows Hai Phong → Vietnam in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Vietnam cohort, uses the shared Asia/Bangkok identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Hanoi's. Against Hanoi, Thanh Hóa follows Thanh Pho Thanh Hoa → Thanh Hoa Province → Vietnam in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Vietnam cohort, uses the shared Asia/Bangkok identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Hanoi's. Against Hanoi, Vinh follows Thanh Pho Vinh → Nghe An Province → Vietnam in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Vietnam cohort, uses the shared Asia/Bangkok identifier, and carries first-order administrative seat rather than capital of a political entity. Its recorded population is below Hanoi's. Its nearest-neighbor distance ranks 650 of 1,206 from shortest to longest in the same snapshot. Hanoi'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 1581130, the coordinate pair 21.0245 / 105.8412, country rank 2 of 13, and neighbor GeoNames 1581298 at 89.253 km bind Hanoi to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Hanoi's reference point is 21.0245° north and 105.8412° east. The IANA identifier Asia/Bangkok is shared by 7 city rows in this catalog, while the GeoNames class PPLC is shared by 129 rows. Hanoi's row carries a first-order administrative label but no second-order label. Hanoi's point falls in the lower-latitude coordinate band used by this atlas's row checks. Hanoi's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Hanoi, 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.
