Buin population
750people · latest figure
Buin has a population of 750, making it the 44th largest place we list in Papua New Guinea. It is in Bougainville.
Buin holds under a tenth of one per cent of Papua New Guinea's 10,947,848 people. Port Moresby, the largest place we list there, is 378 times its size. Twenty years earlier the World Gazetteer recorded 750, almost unchanged.
The 2005 figure comes from the World Gazetteer archive restored on this site. The two sources may draw the settlement's boundary differently, so treat the change as indicative rather than exact. Why figures differ.

Figures are the latest available in GeoNames (CC BY 4.0), which draws on national censuses of varying dates — treat them as recent, not same-year. Country totals are UN World Population Prospects 2024 (medium variant) where the UN lists the country separately; the handful it reports under a parent state keep a GeoNames figure and are marked as such.
