California County Road-User Collision Trends: 2021 and 2023

California OTS county tables report 231,107 people killed or injured in fatal-and-injury collisions across all 58 counties in 2023, compared with 229,586 in 2021. This dataset preserves each county row and source page; it is a two-point comparison, not a continuous annual series or a measure of fault.

Methodology and provenance

The importer requests the official OTS ranking page for every California county for 2021 and 2023, verifies the page identity and required rows, and transcribes only the published victim counts and OTS ranks. Publication requires exactly 116 unique county-year records. Statewide values shown here are sums of one field across the 58 county rows; categories are never added together because a person can appear in the total and in a road-user category.

Publisher trail: Hurt Advice, using California Office of Traffic Safety source tables.

Coverage: 2021/2023; California.

Source documents: 116. Digest method: SHA-256 of the official UTF-8 HTML after replacing only Cloudflare request identifiers that change on every response.

Open primary source collection

What this dataset cannot prove

  • This is a two-point 2021-to-2023 comparison, not a continuous annual trend series. No missing year is interpolated.
  • OTS labels the values as victims killed and injured. They are not counts of crashes, claims, lawsuits, fault findings, or recoveries.
  • Population, travel volume, reporting practices, and exposure differ by county. Raw counts alone should not be used as a risk ranking.
  • The OTS ranks are reproduced as published and should be interpreted through OTS methodology, not as Hurt Advice ratings.
