Rankings

Definition

Traffic fatalities (NHTSA FARS) per 100,000 residents in the same year and place.

Deaths are counted where the crash happened and divided by the resident population, so counties with busy highways and few residents can show very high rates. Differs from the WHO road traffic death rate (road_traffic_death_rate).

How it is calculated

Invokely calculation: NHTSA FARS traffic fatalities divided by the BEA mid-year resident population (Census Bureau estimates, tables SAINC1 and CAINC1) of the same year and place, times 100,000.
