What to know
How Warnely scores regions
Warnely's regional tags are coarse on purpose. Generally safe, caution, and exercise heightened caution reflect the editorial team's read of a region against the country average rather than a continuous numeric score. The country composite at the top of this page is the precise figure; the regional tag is the practical add-on.
The methodology that produces the country score is fully documented at /guides/methodology. The same review cadence applies to regional copy: countries at tier 4 or 5 (High Risk or Do Not Travel) are re-reviewed every 90 days, tier 2 and 3 every 180, and tier 1 annually. Government advisory signals (UK FCDO, US State Department) refresh daily across all 180 countries regardless of tier.
