全球統一尺度的研究估算：以 FBI 2025 年城市執法機構證據為錨點，缺少城市覆蓋的維度使用美國級回退，並明確表達不確定性。
城市研究估算為 75/100；模型尺度上分數越高越安全。 證據日期: · 信賴度: C
顏色反映城市內部的區域證據。 空白處缺少區域證據，不代表安全。

A global-scale research estimate anchored by official 2025 FBI city-agency evidence, with United States-level fallbacks and explicit uncertainty for dimensions without city coverage.
Batch-generated global-scale research estimates. Local signals are used when available; otherwise documented country-level baselines and official current-condition guidance provide a low-confidence first reference. Not travel advice.
Overall-only public-alpha estimate. Supervisor-district variation uses selected person and property incident categories in the San Francisco Police Department's 2025 Incident Reports dataset, grouped by the official supervisor_district field and conservatively anchored to San Francisco's city score. The official DataSF rows were transported through a read-only text proxy after the source host failed TLS from the build network. Counts are selected incident-category records; one incident can carry more than one category. They are not resident or visitor victimization rates, and district population, commuters, tourism, reporting, policing and land use materially affect the pattern. No day/night differences are inferred. Official supervisor-district boundaries are for display; not travel advice.
the repository's staged 2025 snapshot is preliminary and blocked after the final annual release was detected; FBI warns against simplistic city rankings; reported offenses are not traveler exposure; law-enforcement agency coverage may differ from municipal boundaries; Florida and North Dakota have limited 2025 data and are excluded from the first cohort
alerts are not long-term baseline risk; event footprint may not equal traveler exposure; alert severity cannot be copied directly into Safrom score
country-level only; humanitarian risk framing differs from traveler exposure; composite inputs can overlap Safrom dimensions; current event conditions require separate signals
country-level only; reporting and justice-system differences; latest year differs by country; not traveler-specific
country-level only; availability does not measure emergency accessibility; latest year differs by country; distribution within a country is hidden
country-level only; collection is not annual for every country; some values are modeled estimates; resident exposure differs from traveler exposure
country-level only; modeled perceptions rather than traveler incidents; cannot represent neighborhood variation or current events; confidence intervals must not be discarded
