01What the data says — and does not say

02This city's dataset fingerprint
The source row behind Jeju City is GeoNames ID 1846266. Its recorded administrative path is Jeju-si → Jeju-do → South Korea, and GeoNames classifies the place as a first-order administrative seat. Jeju City 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, Jeju City ranks 1,176 by recorded population. Inside the 22 selected South Korea entries it ranks 21; inside the 632 entries in its broad region it ranks 621.

Jeju City sits in the lower half of this atlas's selected South Korea entries. Jeju City's recorded value is materially below the country-cohort median used here.

Jeju City'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 1846266, the coordinate pair 33.5097 / 126.5219, country rank 21 of 22, and neighbor GeoNames 1841811 at 186.452 km bind Jeju City to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Jeju City's reference point is 33.5097° north and 126.5219° 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. Jeju City's row carries both second- and first-order administrative labels. Jeju City's point falls in the middle-latitude coordinate band used by this atlas's row checks. Jeju City's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Jeju City, 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.
