Road type is FARS FUNC_SYS; speeding is any vehicle coded SPEEDREL 2 to 5; drinking is any driver coded DRINKING = 1 (police-reported, not a blood-alcohol test). Road names are the trafficway strings as the police coded them, counted as written, so the same road can appear under two spellings.

How this is counted

  • Fatal crashes are rows in NHTSA’s Fatality Analysis Reporting System (FARS) file FARS2024NationalCSV.zip, accident.csv, one row per crash on a public road in which someone died within 30 days. Deaths are the FATALS field. Counties are the FARS STATE and COUNTY codes joined to Census FIPS codes.
  • Population is the Census Bureau’s July 1 estimate for the same year, county totals, Vintage 2025. Rate per 100,000 = crashes ÷ population × 100,000.
  • The five-year average is total crashes over the years with both inputs ÷ total population over those years × 100,000, the rolling form in 23 CFR 490.207.
  • What it cannot say. FARS has no injury-only or property-damage crashes, no congestion, and nothing about any one driver, trip or road’s risk. A crash is counted where it happened, not where the people lived. Rates are not ranked here; comparing two places means comparing both sets of inputs.
