Where it is
Tonga is grouped in Polynesia, within Roam’s Oceania region. No land neighbours are listed in the source. The source classifies it as not landlocked.
Tonga has a recorded area of 747 square kilometres. Among the 3 countries assigned to Polynesia in this dataset, it ranks 2 by area, from largest to smallest. Samoa is immediately above it in that ordering, at 2,842 km². Tuvalu is immediately below it, at 26 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 103,742 people for Tonga 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 139 people per square kilometre. This calculated average does not describe how evenly people are distributed.
The language entries in the source are English and Tongan. They describe the dataset’s listed languages, not every language spoken by residents. The currency listed for this date is Tongan Paʻanga (TOP). Currency assignments are selected from Unicode CLDR’s date ranges for 23 October 2026; the three-letter codes identify currencies, not countries.
