Bali compared with Singapore: area, population and density

Geography and shape

Bali Province is the island of Bali plus Nusa Penida, Nusa Lembongan and a few smaller islands, just east of Java. Singapore is a city-state on one main island and some sixty smaller islands at the southern tip of the Malay Peninsula.

Population context

Bali Province has 4,461,270 people on 5,590 km², about 798 per km². Singapore has 6,111,175 on 744 km², about 8,211 per km². Singapore has about 1.4 times Bali’s population on about 13% of its land.

Boundaries and definitions

Bali uses the province’s 2025 population figure and its statutory land area, which excludes coastal waters. 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.

Bali Province: Bali Province, not the main island alone. The area is the province's statutory land area, the sum of all 57 districts across its eight regencies and one city as fixed in the 2023 provincial spatial plan; it excludes the 9,152.54 km² of coastal waters the same plan assigns to the province. The population is the provincial figure for 2025, so the density shown is provincial. The province is larger than the main island because it also administers Nusa Penida, Nusa Lembongan, Nusa Ceningan, Menjangan and Serangan — Nusa Penida district alone is 209.02 km², about 3.7% of the land. No Indonesian government body publishes a land area for the main island on its own, and figures circulated as the area of Pulau Bali are provincial totals under an island label. Official provincial areas also disagree by source, from 5,590.01 to 5,780.06 km²; this page names the basis it uses. The outline drawn here is the main island's coastline, because the mapped provincial boundary includes territorial waters and encloses roughly 21,000 km². Area and population are about two years apart.

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.
