Deadliest counties in the US
Every US county ranked by traffic deaths across 2020–2024, and by its average yearly death rate. The largest counties have the most deaths; the highest rates are mostly in rural counties with fewer residents and long distances to drive.
Most traffic deaths, 2020–2024
Highest death rates, 2020–2024
Deaths per 100,000 residents a year, averaged over 2020–2024. Only counties with at least 20 deaths in that time are ranked, because rates based on fewer deaths swing too much from year to year to compare. The rate divides deaths by the people who live in a county, so small counties crossed by busy highways can rank high: many of the people who die there are travelling through. How rates are worked out
