How to read the scores — all on a 0–100 scale, higher is better.

Livability — overall score = 0.35 × Cost + 0.30 × Climate + 0.35 × Safety.
Cost — affordability vs the United States (100 = US prices). Higher = cheaper to live.
Climate — year-round comfort; penalises extreme summer heat, harsh winters and chilly summers.
Safety — combined natural-disaster exposure (earthquake, flood, storm, wildfire, heat, drought, cold, tsunami) and crime (homicide rate). Higher = safer.
Hazard tiers — each disaster type is rated 1 (very low risk) to 5 (very high risk).
