Fatal-crash burden, state by state

Choose a state or DC to inspect its reviewed 2020–2024 FARS profile, then refine the selected-year detail. Every value remains tied to its exact release, small-cell publication rule, and source.

Counts are not risk. They do not account for population, trips, miles, or exposure. Modes can overlap in one crash, so mode counts are not additive and do not imply fault or causation.

One evidence set, five ways to inspect it

The national map and every analytic view are driven by the same 306 reviewed state-by-mode cells. A selection in one view follows you into the others.

State loads the five-year profile. Year and visualization focus drive the national views; publication status filters the matrix and ledger. The complete ledger has its own mode filter below.

Whole-country view

Fatal-crash burden across the United States

Select a road-user mode to read the same reviewed counts geographically. Color is scaled within that mode; hatching means suppressed or zero.

Keyboard: Tab enters the map once. Arrow keys, Home, and End move through jurisdictions in alphabetical order; Enter or Space selects.

Lower published count Higher published count Suppressed or zero

Compare years with care. FARS person-type coding uses one reviewed semantic regime for 2020–2021 and another for 2022–2024. Each result stays pinned to its annual mapping contract, so a cross-regime change can reflect coding as well as outcomes.

Five-year view

Selected-state profile, 2020–2024

Each year is kept separate. The coding seam marks two reviewed FARS person-type regimes, so values on opposite sides should not be read as one continuous series.

Carry the caveat with the number

Evidence brief

Save up to four states. The printable brief keeps the year, mode, publication status, source, and “counts are not risk” limit attached.

Counts are not risk. They do not account for population, trips, miles, or exposure. Modes can overlap in one crash, so mode counts are not additive and do not imply fault or causation.

Auditable rows

Complete state × mode evidence ledger

A published count is the number of distinct fatal crashes with at least one person in that mode. A non-published cell is labeled “suppressed or zero”—never zero.

Source and deployment provenance

The public JSON and release index carry source, mapping, semantic-regime, small-cell publication, and accounting proof. Deployment files bind the published page back to an exact source commit.

What this can answer

  • How many fatal crashes involved each mode in a state in the selected year.
  • Which cells met the small-cell publication floor.
  • Which official release and transformation produced the counts.

What this cannot answer

  • Risk, rate, fault, causation, or a safety ranking.
  • Near misses, nonfatal crashes, counties, streets, or intersections.
  • Whether a non-published cell is zero or suppressed.
Five years, with publication status made explicit

Official source archives are pinned for 2020–2024. Only years whose reviewed public artifacts appear in the release index can be selected; unavailable years are never silently treated as zero.
