The outline is fitted to this frame, not a map for measuring distances. Outlying islands may make the main landmass appear smaller.

The settlements category of Singapore’s national greenhouse gas inventory, which follows the international convention that settlements covers all developed land, including land used for transport and other infrastructure. Parks, golf courses, cemeteries, streetscape trees and bare ground inside developed areas are all counted as developed. Only forest land, wetlands including reservoirs and canals, and cropland are excluded, and since the whole territory is assigned to just four categories, this figure behaves partly as a residual. It should be read against another country’s inventory figure on the same convention, not against a cadastral or planning definition.

Scope and definitions

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.

Place guide

How should this Singapore profile be read?

The area here is 744.3 km² as at 2025-12-31 and the population is 6,111,175 as at 2025-06-30. Both come from official series that have close relatives, and swapping a relative in changes the density substantially.

Which land series, which population concept

The Singapore Land Authority publishes total land area as at 31 December; the 2025 value is 744.3 km², against 735.7 a year earlier, because reclamation adds land and the figure is restated annually. A separate as-at-June land series also exists and reads 736.3 km² for June 2025. An undated Singapore area figure can therefore come from either series and either year.

The population figure is the total population counted by place of usual residence: 3,660,683 citizens, 543,832 permanent residents and about 1.91 million non-residents. Two narrower official concepts circulate beside it, a resident population of 4,204,515 and citizens alone at 3,660,683. Substituting either would cut the density by roughly a third or more.

What the outline actually draws

The rendered outline traces the main island, Pulau Ujong, which is about 88% of the official area. Pulau Tekong, Jurong Island, Pulau Ubin, Sentosa and around sixty smaller islands are inside the 744.3 km² but are not drawn. The shape is therefore narrower than the number beside it.

The two figures also sit six months apart, area at end-December and population at end-June. Neither gap is large enough to distort the sense of scale, but both belong with the numbers whenever they are quoted.
