2025 police-recorded road crashes, spatially joined to 57 Prague municipal districts. The local metric is the share involving injury or death, stabilized with 20 crash equivalents at the city mean. It is not crime or individual crash probability.
11,029 crashes join exactly one municipal district, including 2,095 injury/fatal crashes. The police Prague jurisdiction has 11,014 crashes and is not identical to the municipal boundary; four jurisdiction-coded points do not join. No points are snapped to a district.
Sparse districts are shrunk toward the city injury share; raw aggregate counts are retained. Reporting rules changed during 2025, including the property-damage reporting threshold. Compare only this same-period recorded-crash series.

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