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 73/100；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.
Public-alpha research estimate centered on Boston's global city score. Police-district variation uses Boston's official 2025 incident table grouped into violent and property categories, balanced with official district polygon-area density through a conservative robust transform. These are recorded incidents, not resident or visitor victimization rates; population, commuting, tourism, reporting, enforcement and land use materially affect the pattern. Overall only; 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
