Where it is
South Korea is grouped in Eastern Asia, within Roam’s Asia region. Its land-border list includes 1 country in this atlas: North Korea. The source classifies it as not landlocked.
South Korea has a recorded area of 100,210 square kilometres. Among the 5 countries assigned to Eastern Asia in this dataset, it ranks 5 by area, from largest to smallest. North Korea is immediately above it in that ordering, at 120,538 km². This comparison uses the source’s area figures and subregions, not a ranking of all territories.
The marker shows the atlas location. Small countries may be too small for an outline at this scale. Map boundaries are illustrative.
People, languages and currency
The World Bank records 51,684,564 people for South Korea in 2025. This is the latest non-empty annual observation in Roam’s committed 2020–2025 download, rather than a live population counter. Dividing that population by the source area gives approximately 516 people per square kilometre. This calculated average does not describe how evenly people are distributed.
The language entries in the source are Korean. They describe the dataset’s listed languages, not every language spoken by residents. The currency listed for this date is South Korean Won (KRW). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
