2024 police-recorded injury/fatal road crashes, Rome statistical yearbook 2025, table 15.29 page 34. Local metric: deaths per 1,000 injury/fatal crashes, stabilized with 20 crash equivalents at the city mean.
The denominator excludes property-damage-only crashes. This measures severity among recorded crashes, not crash frequency, crime, or the probability a visitor is injured. Small death counts remain volatile.
15 municipal districts; observations join by official Municipio number. All district totals reconcile: 13,016 crashes, 128 deaths and 15,920 injured. No population or visitor exposure denominator is used.
Istat 2021 submunicipal boundaries, release updated May 2026, are generalized orientation geometry. Every district overlaps current Roma Capitale geometry by more than 98% intersection-over-union. Boundary differences remain; geometry is not a legal boundary.

The citywide score uses Italy national priors. Local evidence adjusts only mobility.
