How big is Tonga?

By population, Tonga ranks 184th in the world, holding roughly well under a hundredth of a percent of all people on Earth. By land area it ranks 177th.

Those two numbers rarely match, and the gap between them is the interesting part. Tonga has 143 people per square kilometre, which is about 2.4 times the world average of 59.4. It is more spacious than its population alone would suggest.

Within Oceania, Tonga is the 10th most populous country of 14.

Countries of a similar size

By land area, its closest counterparts are Dominica (751 km²) and Bahrain (765 km²).

Comparisons like these are worth more than raw figures when you are trying to remember them. A number on its own is hard to hold; a number next to a country you already have a feel for is much easier.

Language and currency

Tongan is listed as an official language of Tonga alone, which is unusual — most official languages are shared across borders.

Tonga uses the TOP, and it is the only country that does, which makes the currency name a reliable one-to-one clue.
