About these numbers
FARS counts every crash on a public road in which someone died within 30 days. It leaves out the far larger number of crashes that only injured people. Places are as coded in the report: a crash on a county road just outside city limits counts for the county, not the city. Rates use the Census 2024 population estimate and the five-year average.
