有来源的研究估算；本地覆盖不完整，部分维度沿用更广地理范围的基线。
城市研究估算为 82/100；模型尺度上分数越高越安全。 证据日期: · 置信度: D
研究估算：区域仅调整有当地证据的一个维度，其他维度沿用城市或国家基线。 空白处缺少区域证据，不代表安全。

Compare Florence areas on the map, with local evidence and source details.
Local evidence is the ISPRA national 2020 P2 flood-hazard mosaic (v5.0), using the approximately 100–200-year return-period scenario. It is a historical structural exposure baseline, not a current flood warning or current legal planning boundary; later local PGRA amendments are not incorporated. District metric is the percentage of land intersecting mapped P2 flood polygons. It does not measure a visitor’s probability of harm, building protection, flood depth, or crime. All five districts have positive mapped exposure; unmapped land is not classified as flood-free. Five Istat 2021 city quarters, May 2026 release; area calculated in UTM 32N before geometry simplification. Only disaster_and_environment varies locally; all other dimensions retain explicitly labelled Italy national priors.
