Probability sample: NO state/county geography by design (suppressed). Weighted — weighted sums estimate national totals; not census-comparable with FARS. |

Built by pipelines/exposure/build_fhwa_csv.py into pipelines/exposure/data/fhwa_vm2_dl1c.csv (2,192 state-year cells). Authoritative denominator — fatalities_per_mvmt computes. |
