Daejeon Metropolitan City's full administrative territory, an inland city with no offshore islands. Population is resident registration population (주민등록인구) as at 2025-12-31, from this ministry's own annual administrative-area-and-population report — a different series from the Statistics Korea register-based census (등록센서스) that the South Korea and Seoul pages use, though the two series are usually close. Area is this same report's official administrative-area figure at 2025-12-31, not a figure computed from the map outline. This ministry's own administrative-area total for South Korea (100,517.62 km² at 2025-12-31) differs by about 0.06% from the 100,459.9 km² cadastral figure the South Korea and Seoul pages use, a small gap between two different official area series rather than an error.

Place guide
How should this Daejeon profile be read?
Daejeon Metropolitan City is 539.83 km² with 1,440,729 people as at 2025-12-31, an inland city whose outline needed none of the sea-boundary corrections other Korean metros on this site required.
A clean case: no islands, no maritime boundary
Daejeon has no coastline and no offshore islands, so its OpenStreetMap administrative relation measures within 1% of the official area figure. That is not true of every metropolitan city on this page: Busan and Incheon were skipped for this reason, and Ulsan’s outline was switched to a different source.
The reference date is 2025-12-31 for both area and population, from the Ministry of the Interior and Safety’s own annual report rather than a separately sourced land survey.
Resident registration, not the register-based census
The population figure is resident registration population (주민등록인구), the series this ministry itself compiles monthly. It differs in universe from the Statistics Korea register-based census used on the South Korea and Seoul pages, though the two are usually close.
Density works out to about 2,669 people per km², simple division rather than a published figure, and it inherits both reference dates above.
