Source: NHTSA's Fatality Analysis Reporting System (FARS), 2019–2024, which records every crash on a public road in which someone died within 30 days. Population figures are the Census Bureau's 2024 county estimates. A crash is counted where it happened, not where the people involved lived. “Drinking driver” means police reported a driver had been drinking; “speeding” means police reported at least one driver was speeding or going too fast for conditions. Injury-only crashes aren't in FARS.
