About Tonga

Strung along the western rim of the Tonga Trench, where the ocean floor drops to one of its deepest points, Tonga’s islands fall into three main groups. Tongatapu is flat raised coral around a broad lagoon, with blowholes spouting along its southern shore. Haʻapai is a scatter of low islands beside the volcanic cones of Tofua and Kao. Vavaʻu, to the north, breaks into limestone islands and channels around Port of Refuge, where humpback whales come each winter to calve.

Lapita settlers landed on Tongatapu nearly three thousand years ago. By the thirteenth century the sacred Tuʻi Tonga kings held sway as far as Samoa. James Cook called them the Friendly Islands in the 1770s. George Tupou I unified the islands, embraced Methodism and gave Tonga a written constitution in 1875. Never annexed, Tonga was a British protected state from 1900 until June 1970. Queen Sālote Tupou III rode in an open carriage through the rain at the coronation of 1953.

The constitution keeps Sunday holy, so shops close and families go to church in taʻovala, woven mats tied around the waist. Women’s groups beat mulberry bark into ngatu, painted tapa cloth given at weddings and funerals. Feasts come from the ʻumu with lu pulu, corned beef in taro leaves and coconut cream. Households lean on money sent by relatives in Auckland, Sydney and California; squash for Japan, vanilla and kava are the main crops, and whales draw visitors to Vavaʻu.

02Country Index 2026

Where it stands, topic by topic

Strongest first. Each position is Tonga’s place among the countries with a standing on that topic, built from a few key statistics chosen to measure different things.

All topics

Each standing is built from a few key statistics chosen to measure different things. Select a subject for Tonga’s readings on it, or see every statistic held for Tonga in the table further down this page.

03Highs and lows

Where Tonga stands out

The two ends of its own record: every statistic on which Tonga sits within ten places of the best or worst in the world, plus its strongest and weakest readings overall. Each is turned into a percentile — its place among every country measured — which is what lets a hunger score and a press-freedom rank be compared at all.

Where Tonga does best6

In the top third of all countries measured. 5 are within ten places of the best in the world, in a field of at least 50 countries — marked with that place.

A band is a place among the countries each publisher scores, so Tonga can move because other countries moved. See the Country Index for the full method.

Sources and how to read them

How to read this page

  • The scores and ranks belong to their publishers. Nothing is adjusted, rescaled or re-ranked; each is reproduced from the edition named beside it. Where a row says position · derived, the publisher ranks nobody on that measure and the position is ours, made by ordering the published score.
  • Each statistic shows its newest edition, which is not always the edition the Country Index uses: the index pins every source to one data year so its average compares like with like.

How a standing is built from percentiles, why Tonga can move because other countries moved, and why publishers measure between 120 and 215 countries each are set out in full in how a standing is made and what a standing cannot tell you.

Sources

  • Statistics: 37 publishers, each named beside its numbers, with every edition and licence on the datasets pages.
  • Capital, languages, currency, codes: Wikidata, public domain (CC0).
  • Map and land borders: Natural Earth, public domain. Borders are de facto — where administration actually changes — not claimed.
