About this ranking

People killed in motor vehicle traffic crashes during the year. FARS counts people who die within 30 days of a crash involving a motor vehicle travelling on a public road, by the place of the crash, not of residence.

A police-based count of deaths. It differs from death certificate counts (CDC) and from the WHO road traffic death rate (road_traffic_death_rate), which is modelled for international comparison.

Every value in the ranking comes from the same publisher and the same period, so the counties are compared on one definition. Equal values share a rank.
