Incheon

Source identity and administrative path

The source row behind Incheon is GeoNames ID 1843564. Its recorded administrative path is Incheon → South Korea, and GeoNames classifies the place as a first-order administrative seat.

Incheon 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, Incheon ranks 118 by recorded population. Inside the 22 selected South Korea entries it ranks 3; inside the 632 entries in its broad region it ranks 79.

Its 3,015,482 population value is 3.41 times the 883,490 median for the country cohort and 2.99 times the 1,008,426 regional median. Incheon falls inside the leading tenth of this atlas's South Korea population cohort.

Incheon'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.

Nearest-reference pattern

Incheon's three nearest other atlas coordinates are Bucheon-si at 8.338 km with 850,731 recorded people; Ansan-si at 18.019 km with 623,256 recorded people; Anyang-si at 20.837 km with 595,644 recorded people. The closest-to-farthest distance spread is 12.499 km. Compared with Bucheon-si, Incheon's recorded population is 3.54 times as large. Against Incheon, Bucheon-si follows Bucheon-si → Gyeonggi-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 Incheon's. Against Incheon, Ansan-si follows Ansan-si → Gyeonggi-do → 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 populated place rather than first-order administrative seat. Its recorded population is below Incheon's. Against Incheon, Anyang-si follows Anyang-si → Gyeonggi-do → 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 populated place rather than first-order administrative seat. Its recorded population is below Incheon's. Its nearest-neighbor distance ranks 129 of 1,206 from shortest to longest in the same snapshot. Incheon'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 1843564, the coordinate pair 37.4565 / 126.7052, country rank 3 of 22, and neighbor GeoNames 1838716 at 8.338 km bind Incheon 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

Incheon's reference point is 37.4565° north and 126.7052° 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. Incheon's row carries a first-order administrative label but no second-order label.

Incheon's point falls in the middle-latitude coordinate band used by this atlas's row checks. Incheon's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Incheon, 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.
