Two and a half Singapores of land, a ninth of the people.

Geography and shape

Jeju is a volcanic island off the southern tip of the Korean Peninsula, with a few small islets, governed as one province. Singapore is a city-state on one main island and some sixty smaller islands at the southern tip of the Malay Peninsula.

Population context

Jeju Province has 674,817 people on 1,850 km², about 365 per km². Singapore has 6,111,175 on 744 km², about 8,211 per km². Singapore holds about 9 times Jeju’s population on about 40% of its land.

Boundaries and definitions

Jeju uses its register-based census for 1 November 2024 and the province’s registered land, main island plus islets. Singapore uses its total land area at 31 December 2025, which grows with reclamation, and its total population at end-June 2025, including about 1.91 million non-residents.

Jeju Province: Jeju Special Self-Governing Province, not the main island alone. The area is the province's registered cadastral land at 31 December 2024, covering the main island plus Udo, the Chuja group, Gapado, Marado, Biyangdo and dozens of smaller islets; the population is the province's at the 1 November 2024 register-based census. The main island by itself is roughly 0.9% smaller in area and 0.5% smaller in population, but no Korean government body publishes an area for it alone, so no separate island entry is possible. The outline drawn here is the main island's coastline rather than the provincial boundary, because the mapped provincial relation is a maritime jurisdiction line enclosing about 11,100 km² of mostly open sea. The Chuja Islands, some 50 km north, are therefore counted in the figures but do not appear in the outline.

Singapore: Total land area surveyed by the Singapore Land Authority as at 31 December 2025, covering the main island and its offshore islands. The figure rises with reclamation and is restated annually — it was 735.7 km² a year earlier. Population is the Department of Statistics total population at end-June 2025: citizens 3,660,683, permanent residents 543,832 and about 1.91 million non-residents, counted by place of usual residence, so tourists and short-term visitors are excluded. The two dates are six months apart, and the outline traces the main island, Pulau Ujong, which is about 88% of the official area — Pulau Tekong, Jurong Island, Pulau Ubin, Sentosa and some sixty smaller islands are counted in the figure but not drawn.
