Where it is
Indonesia is grouped in South-Eastern Asia, within Roam’s Asia region. Its land-border list includes 3 countries in this atlas: Timor-Leste, Malaysia, Papua New Guinea. The source classifies it as not landlocked.
Indonesia has a recorded area of 1,904,569 square kilometres. Among the 11 countries assigned to South-Eastern Asia in this dataset, it ranks 1 by area, from largest to smallest. Myanmar is immediately below it, at 676,578 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 285,721,236 people for Indonesia 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 150 people per square kilometre. This calculated average does not describe how evenly people are distributed.
The language entries in the source are Indonesian. They describe the dataset’s listed languages, not every language spoken by residents. The currency listed for this date is Indonesian Rupiah (IDR). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
