01What the data says — and does not say
This page separates the checked GeoNames row for Changwon—1,025,702, Asia/Seoul, 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: specific city in South Gyeongsang, South Korea.
02This city's dataset fingerprint
The source row behind Changwon is GeoNames ID 1846326. Its recorded administrative path is Changwon-si → Gyeongsangnam-do → South Korea, and GeoNames classifies the place as a first-order administrative seat. Changwon 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.
Within the fixed 1,206-record atlas, Changwon ranks 531 by recorded population. Inside the 22 selected South Korea entries it ranks 10; inside the 632 entries in its broad region it ranks 310. Its 1,025,702 population value is 1.16 times the 883,490 median for the country cohort and 1.02 times the 1,008,426 regional median. Changwon sits in the second quarter of this atlas's South Korea population cohort. Changwon'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.
Changwon's three nearest other atlas coordinates are Kimhae at 18.178 km with 531,966 recorded people; Busan at 34.692 km with 3,285,147 recorded people; Ulsan at 67.094 km with 1,098,421 recorded people. The closest-to-farthest distance spread is 48.916 km. Compared with Kimhae, Changwon's recorded population is 1.93 times as large. Against Changwon, Kimhae follows Gimhae-si → Gyeongsangnam-do → South Korea in the source. Its point has higher latitude and higher longitude; it belongs to the same selected South Korea cohort, uses the shared Asia/Seoul identifier, and carries populated place rather than first-order administrative seat. Its recorded population is below Changwon's. Against Changwon, Busan follows Busan → South Korea in the source. Its point has lower latitude and higher longitude; it belongs to the same selected South Korea cohort, uses the shared Asia/Seoul identifier, and carries the same first-order administrative seat class. Its recorded population is above Changwon's. Against Changwon, Ulsan follows Ulsan → South Korea in the source. Its point has higher latitude and higher longitude; it belongs to the same selected South Korea cohort, uses the shared Asia/Seoul identifier, and carries the same first-order administrative seat class. Its recorded population is above Changwon's. Its nearest-neighbor distance ranks 249 of 1,206 from shortest to longest in the same snapshot. Changwon's nearest-coordinate gap falls between the tightest tenth and quarter of the atlas. 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 1846326, the coordinate pair 35.2281 / 128.6811, country rank 10 of 22, and neighbor GeoNames 1842943 at 18.178 km bind Changwon to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Changwon's reference point is 35.2281° north and 128.6811° east. The IANA identifier Asia/Seoul is shared by 22 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Changwon's row carries both second- and first-order administrative labels. Changwon's point falls in the middle-latitude coordinate band used by this atlas's row checks. Changwon's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Changwon, 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.
