Where Tonga sits
Tonga 🇹🇴 is one of 14 countries in Oceania, with its capital at Nukuʻalofa. It covers 747 square kilometres — 177th in the world — and is home to about 106,858 people, 184th globally.

How Tonga compares
Raw figures are hard to hold on their own, so it helps to anchor them. In population, Tonga sits closest to Seychelles and Saint Vincent and the Grenadines. In land area, its nearest counterparts are Dominica and Bahrain.
At 143 people per square kilometre it is about 2.4 times the world average of 59.4. It ranks higher by area than by population, so it is more spacious than its population alone suggests.
Tongan is listed as official in Tonga alone. The TOP is used by Tonga and no one else.
