What the Data Shows

Jefferson Davis County, Mississippi recorded 42 total road fatalities across 39 reported crashes during the 2016-2023 reporting window, according to NHTSA's Fatality Analysis Reporting System. The most recent year covered by the data logged 3 deaths on county roads, and the annual average works out to approximately 4.7 fatalities per year. Adjusted for population, the fatality rate is 42.8 per 100,000 residents, which puts it among the most dangerous one in ten U.S. counties by that per-capita measure among the 3,137 U.S. counties in this dataset.

Cause-code breakdowns are not individually published for Jefferson Davis County in the current FARS release, so readers looking for contributing-factor data should use the Mississippi state page, which aggregates county-level case files into statewide totals. Either way, the underlying records are drawn from a census of fatal crashes, not a statistical sample, so the counts are actual deaths rather than estimates.

The directional trend for Jefferson Davis County is increasing, which means annual fatalities have risen across the reporting period and may warrant closer attention from local transportation and enforcement agencies. Residents, insurers, and policy analysts can use this baseline alongside population density, highway mile data, and rural-versus-urban road mix to judge whether Jefferson Davis County's 42-death total is proportionate to its exposure. All numbers are for research and informational use only.
