How the Safety Score is built
One composite, four public sources, weighted to reflect what changes a buyer's risk on the ground — and honest about where the data runs out.
UNODC intentional-homicide rate · 40%
The heaviest single input is the UN Office on Drugs and Crime intentional-homicide rate per 100,000 people, the most internationally comparable hard crime statistic available. We use the most recent reporting year UNODC has published per country. Where sub-national figures exist they drive the regional grades; where they do not, regions inherit the national rate and we say so on the page.
US State Department travel advisory · 20%
The State Department four-level advisory, mapped to a 0–100 contribution (L1 = 100, L2 = 70, L3 = 40, L4 = 0). Country-level only; localized do-not-travel carve-outs are noted in the per-source disclosure rather than folded into the national number.
Government of Canada travel advice · 20%
The Canadian advisory, mapped on the same scale. We carry it as an independent voice rather than averaging it with the US reading, so a divergence between the two surfaces instead of disappearing.
UK FCDO travel advice · 20%
The UK Foreign, Commonwealth & Development Office advice, mapped from its phrasing to the same 0–100 scale. The mapping rule used for each market is stated inline on the country page.
