01What the data says — and does not say
This page separates the checked GeoNames row for Daejeon—1,441,203, 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.

02This city's dataset fingerprint
The source row behind Daejeon is GeoNames ID 1835235. Its recorded administrative path is Daejeon → South Korea, and GeoNames classifies the place as a first-order administrative seat. Daejeon 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, Daejeon ranks 340 by recorded population. Inside the 22 selected South Korea entries it ranks 5; inside the 632 entries in its broad region it ranks 197. Its 1,441,203 population value is 1.63 times the 883,490 median for the country cohort and 1.43 times the 1,008,426 regional median. Daejeon falls between the leading tenth and quarter of this atlas's South Korea population cohort. Daejeon's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Daejeon's three nearest other atlas coordinates are Cheongju-si at 33.376 km with 852,147 recorded people; Cheonan at 54.939 km with 658,831 recorded people; Jeonju at 62.34 km with 638,421 recorded people. The closest-to-farthest distance spread is 28.964 km. Compared with Cheongju-si, Daejeon's recorded population is 1.69 times as large. Against Daejeon, Cheongju-si follows Cheongju-si → North Chungcheong → 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 below Daejeon's. Against Daejeon, Cheonan follows Cheonan-si → Chungcheongnam-do → South Korea in the source. Its point has higher latitude and lower 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 Daejeon's. Against Daejeon, Jeonju follows Jeonju-si → Jeollabuk-do → South Korea in the source. Its point has lower latitude and lower 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 below Daejeon's. Its nearest-neighbor distance ranks 338 of 1,206 from shortest to longest in the same snapshot. Daejeon's nearest-coordinate gap sits in the second quarter 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 1835235, the coordinate pair 36.3491 / 127.3849, country rank 5 of 22, and neighbor GeoNames 1845604 at 33.376 km bind Daejeon to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Daejeon's reference point is 36.3491° north and 127.3849° 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. Daejeon's row carries a first-order administrative label but no second-order label. Daejeon's point falls in the middle-latitude coordinate band used by this atlas's row checks. Daejeon's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Daejeon, 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.
