South Chungcheong Province's full administrative territory on the west coast, including its offshore islands. Daejeon and Sejong are separate top-level governments and are not included. Population is resident registration population (주민등록인구) at 2025-12-31 and area is the official administrative-area figure at the same date, both from the Ministry of the Interior and Safety annual report already used for Busan, Incheon, Daegu, Daejeon, Ulsan and Sejong — a different population series from the Statistics Korea register-based census (등록센서스) behind the South Korea and Seoul pages, though the two are usually close.

Place guide
South Chungcheong Province covers 8,248.25 km² and had 2,136,753 registered residents at year-end 2025, about 259 people per km². Its most populous city is Cheonan, on the rail line south from Seoul.
The Taean and Boryeong coast is deeply indented and fringed with islands, which is why GADM draws the province in more than a hundred separate pieces. Together they still measure within 0.2% of the official land area.
Daejeon, which borders the province, has been a separate metropolitan city since 1989, and Sejong was created in 2012 largely from the province's former Yeongi County. Neither is in these figures; both have their own pages.
