01The evidence
The 4 key statistics that decide it
Only these place Tonga on risk & resilience — one vote each. Every value is the publisher’s own, read at the edition the Country Index 2026 used — or, for a survey-based key, each country’s latest reading; the grey ticks are every other country it was compared with, lowest on the left.

08Method
Method, sources and how to cite
What this topic does not measure
This topic does not forecast when a disaster will strike, and it does not measure financial or economic risk. Water stress is measured under Environment & Sustainability. Displacement caused by disasters and the severity of crises already under way are published here as context.
How the Risk & Resilience standing is decided
A standing is this site’s ordering, named with its edition — never a publisher’s rank. 4 key statistics vote, one vote each; every country’s published value becomes a place within that key’s own field, the places are averaged, and the average is never published. A country needs 2 of the 4 keys to be placed.
