Risk Score Methodology

How Warnely rates country safety. The headline risk score is a composite of four signals weighted 50/30/15/5. Every input is documented below, with sources, review cadence, and the things the score is not designed to tell you.

The composite formula #

Every country in the Warnely dataset carries a single 0–100 risk score (lower is safer) and a five-tier label. The score is a weighted composite of four independent signals:

ComponentWhat it measuresWeight
EditorialSix-category editorial assessment of typical traveller risk50%
Authority signalsUK FCDO and US State Department travel advisories (worst-of)30%
Structural indicesGlobal Peace Index and World Governance Indicators15%
Live signal30-day rolling incident pressure from the Warnely wire5%

Formula in full: score = 0.50 × editorial + 0.30 × authority + 0.15 × structural + 0.05 × live. When a component is missing for a country (a small structural-index data set leaves about 17 countries without GPI or WGI coverage), the remaining weights are renormalised so the formula still sums to 100.

All four components sit on the same 0–100 risk scale, where 0 is the lowest risk and 100 the highest. The four are deliberately independent. Authority signals capture official government advice, structural indices capture long-run institutional health, the live signal captures short-term volatility, and the editorial layer is the categorical breakdown that the other three cannot resolve at the kind of granularity a traveller actually uses (drug law, women's safety, LGBTQ+ status, scams, transport reliability, and so on).

Editorial component (50% weight) #

The dominant input. An editorial 0–100 risk score for each country, derived from six category scores. Each category gets a 1–5 rating; the headline editorial score is a weighted roll-up of the six.

CategoryWhat it coversWeight
CrimeViolent crime, theft, scams, kidnapping risk for tourists20%
TerrorismTerror threat level, recent attacks, regions to avoid20%
Natural disastersEarthquakes, cyclones, floods, volcanic, wildfire risk15%
HealthDisease prevalence, water safety, healthcare quality, evacuation needs15%
Civil unrestProtests, political instability, ethnic or sectarian tensions15%
InfrastructureRoad safety, transport reliability, communications, utilities15%

How to read a category score

1
LowNegligible risk for the typical traveller. No special precautions beyond common sense.
2
Low to ModerateReal but manageable risk. Standard travel precautions usually sufficient.
3
ModerateNotable risk in specific contexts (certain neighbourhoods, seasons, or activities). Plan around it.
4
HighSerious, frequent, or geographically broad risk. Active precautions needed; some travellers should reconsider.
5
ExtremeSevere and ongoing. Most government advisories will recommend against travel.

Authority signals (30% weight) #

The combined verdict of two authoritative government advisories. Both are scraped daily and stored alongside the country record.

The two sources are combined worst-of. The authority component on the 0–100 risk scale is the maximum of the two source signals, mapped as follows:

SourceCode or levelValue
FCDOAdvise against all travel (whole country)95
FCDOAdvise against all travel (parts of country)70
FCDOAdvise against all but essential travel (whole country)60
FCDOAdvise against all but essential travel (parts)30
US StateLevel 4: Do Not Travel95
US StateLevel 3: Reconsider Travel70
US StateLevel 2: Exercise Increased Caution20
US StateLevel 1: Exercise Normal Precautions0

So a country at FCDO advise-against-all-essential (whole country) plus US State Level 3 takes the worst-of: 70. Multiplied by the 30% authority weight, that contributes 21 points to the composite. The original FCDO and US State labels are preserved verbatim on every country guide.

Structural indices (15% weight) #

Long-run institutional health, captured by two indices that change on years not weeks. The structural component is a weighted blend of:

Both indices are converted to the same 0–100 risk scale, blended, and applied at 15%. The component is omitted (and the remaining weights renormalised) for the 17 countries without coverage in both indices, mostly small Pacific island states.

Live signal (5% weight) #

The 30-day rolling incident pressure from the Warnely wire. The wire ingests Reuters, BBC, AP, AFP, Al Jazeera, Guardian, USGS earthquake feed, GDACS, ReliefWeb, Met Office severe weather, EA Floods, and several other safety-relevant feeds. Incidents are classified, geocoded, and severity-rated by a downstream pipeline.

The live component is computed as min(100, 5 × incidentCount + 2 × severeCount) across the last 30 days for the country. Multiplied by the 5% live weight, a single severe incident in the window contributes 0.35 to the composite. Twenty incidents (most of them routine) contribute 5.

The weight is intentionally low. A small static weight protects the composite from churn during transient news cycles. The wire itself is exposed on every country guide as a separate live-alerts panel so travellers can read short-term signal alongside the static rating without one swamping the other.

Score-to-tier mapping #

Composite scoreTier labelLevel
0 to 20Very Safe1
21 to 35Exercise Normal Caution2
36 to 55Exercise Increased Caution3
56 to 75High Risk4
76 to 100Do Not Travel5

Boundaries are calibrated against the two government sources so a country at tier 4 or 5 on the Warnely scale almost always carries an FCDO advise-against and a US State Level 3 or 4.

Review cadence #

Every country guide carries a visible Last reviewed date and a Next review by commitment. The cadence is tied to the country's current risk tier:

Current tierReview cadenceNext review window
Do Not Travel (5)Quarterly, with rolling daily sweeps of the FCDO and US State pages90 days
High Risk (4)Quarterly90 days
Exercise Increased Caution (3)Half-yearly180 days
Exercise Normal Caution (2)Half-yearly180 days
Very Safe (1)Annual, with daily authority-signal monitoring365 days

Authority signals (FCDO and US State levels) are refreshed daily across all 180 countries regardless of tier, so changes there propagate within 24 hours even when the editorial layer is not due for review. The full editorial layer is what the cadence above governs.

Where the data comes from #

Country profiles draw on a mix of authoritative public sources and Warnely's own incident data. An editor reads each source and synthesises the picture for travellers rather than scraping blindly.

Persona reweighting #

The default composite answers a single question: what does the average traveller's risk profile look like in this country? The dashboard's View as selector reweights the same category scores to answer the question for a specific kind of traveller. The underlying category data does not change. Only the rollup does.

The persona-weighted score is shown alongside the default with a delta versus default indicator so the shift is visible. The weighting rules:

The persona is persisted in the URL (?persona=soloFemale) so a link can be shared with the right read already applied.

Visa & entry #

Every country profile carries a structured visa block: type (six categories), length, cost, official application URL where applicable, and a paragraph note covering recent changes. Six visa types, colour-coded:

Critical caveat: this data assumes a Western traveller (UK, US, EU, Canada, Australia, NZ passport). Other passports face very different requirements. Sometimes more permissive (Indian and Chinese passports get free 30-day visa-free entry to Mongolia and Iran where Western passports need eVisas), often more restrictive. For any non-Western passport, the official answer is the IATA Travel Centre. Every visa block links there directly.

Recent changes flagged in the data:

Always re-verify within a week of booking. Visa policy changes faster than any other safety data. New requirements, fee changes, and document validity rules can shift on weeks-not-years cadence. The note on each block highlights what changed recently; the IATA link gives the authoritative current answer.

Drug laws #

Drug law mistakes by tourists are a leading cause of foreign-citizen prosecutions, and the consequences can include the death penalty. Every country profile carries a structured drug-law block with three signals: severity tier, cannabis-specific status, and a paragraph traveller note covering the things that actually catch travellers out.

Six severity tiers, colour-coded:

The cannabis status is broken out separately because it is the most common traveller-relevant question and the legal landscape has shifted dramatically in the last five years. What was illegal a year ago may be legal now and vice versa (Thailand legalised in 2022 then re-restricted in 2024).

Specific traveller traps the notes call out:

Sources: UK FCDO drug warnings per country, US State Department travel advisories, Harm Reduction International's annual death-penalty-for-drugs report. Always cross-check the FCDO page (linked from each block) before travel. Drug laws change faster than most other safety data.

Women's safety #

Every country profile carries a structured Women's Safety rating with a one-paragraph traveller note. Five tiers, colour-coded:

Notes are deliberately specific. What kind of hassle, where, and what reduces it, rather than generic "exercise caution." The rating reflects current consensus from women-traveller communities, government advisories, and published assault statistics. The Warnely editorial line is to err on the harsher side when sources disagree.

LGBTQ+ legal status & social climate #

Every country profile carries a structured LGBTQ+ Travellers block with three signals: legal status, social climate, and a one-paragraph traveller note covering PDA, scene visibility, dating-app risk, and any recent enforcement trends. Six legal-status tiers:

Five social-climate tiers (progressive, accepting, mixed, conservative, hostile) capture lived experience separately from the legal status. A country can be legally permissive but socially conservative, or the reverse. The Warnely editorial line grades conservatively: when in doubt the country gets the harsher rating.

Always verify on Equaldex. LGBTQ+ law changes faster than most other safety data. New criminalisation bills, court rulings, and enforcement shifts happen on weeks-not-years cadence. Every block links directly to the country's Equaldex page so a traveller can check current status and recent enforcement before booking. The persona-weighted score for LGBTQ+ travellers boosts Crime and Civil Unrest as a proxy until this data is integrated into the live signal.

Currency & tipping #

Every country profile carries a daily-budget block (backpacker, midrange, luxury) in local currency with USD equivalents, and a structured tipping note covering restaurants, taxis, and hotel staff specifically. Not just a generic "10% at restaurants."

Two principles guided the fill-in:

Specific cultural notes the tipping block calls out:

Numbers are 2026 estimates from World Bank GNI data, Numbeo cost-of-living, and traveller-forum consensus. Budget figures shift quickly with currency volatility. Verify in the week before booking, especially for Argentina, Venezuela, Lebanon, Turkey, Iran, and Sri Lanka where parallel exchange rates can dramatically change effective costs.

Essential phrases #

Each country profile carries five essential phrases in the local language: hello, thank you, yes / no, sorry, and help! with the native script and an approximate Latin phonetic. The capitalised letter in each phonetic shows the stressed syllable.

Phrases ship for 26 languages Warnely can verify (Spanish, French, Italian, Portuguese, German, Dutch, Greek, Turkish, Russian, Polish, Czech, Hungarian, Croatian, Swedish, Norwegian, Danish, Finnish, Icelandic, Thai, Vietnamese, Indonesian and Malay, Japanese, Korean, Mandarin Chinese, Hindi, Arabic, Hebrew). Multilingual countries (Switzerland, Belgium, South Africa, Singapore, Canada) are skipped on the principle that the wrong primary-language pick is worse than no pick at all. English in those countries gets a traveller reliably understood.

Arabic uses Modern Standard Arabic, broadly understood across the Arabic-speaking world but not the colloquial dialect anywhere. Egyptian, Levantine, Maghrebi, and Gulf Arabic each have their own local forms. The MSA phrases here will be understood and read as polite or formal. Hindi is shipped for India even though India has 22 scheduled languages. It is the most widely usable single choice but not universal, especially in southern states where English is often a more reliable option.

Phrases are double-checked against multiple sources (Lonely Planet language guides, Omniglot, the relevant Wikipedia language pages). If you see a wrong romanisation or a script error, email us. Phonetic conventions vary and we erred toward the most common English-traveller convention.

Quick facts #

Every country profile carries a Quick Facts card: plug type, mains voltage, timezone, driving side, and tap-water safety. These are the things travellers check repeatedly and the answers do not need long-form prose. The card lives in the right-hand panel of the dashboard.

Tap-water classifications are conservative: safe means generally drinkable from public taps in most cities; caution means it varies by region or treatment status (locals often drink it but a sensitive traveller may want bottled or filtered); unsafe means stick to bottled or properly treated water. When in doubt, default to bottled. The cost of being wrong about water is very high.

Country deep-dive pages #

Every country in the dashboard also has a long-form landing page at /guides/is-<country>-safe. Useful when you want a single page to read or share rather than the interactive dashboard. The pages are generated from the same dataset, so the headline score, breakdown, advisories, and Quick Facts always match. Twelve countries (Brazil, Colombia, Egypt, India, Indonesia, Japan, Mexico, Morocco, South Africa, Thailand, Turkey, Vietnam) have additional hand-written prose; the rest are template-driven.
