What to know
Why this page exists. Country-level scores tell you whether a destination is worth considering. Region-level pages like this one answer the next question: where in this country, and what should I plan around. The body above is taken from the editorial review of Indonesia; the safety tag is the same one used on the country page.
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.
