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. 2 are within ten places of the best in the world, in a field of at least 50 countries — marked with that place.

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: 27 publishers, each named beside its numbers, with every edition and licence on the datasets pages.
