What the Data Shows

Clarendon County, South Carolina recorded 120 total road fatalities across 111 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 16 deaths on county roads, and the annual average works out to approximately 13.3 fatalities per year. Adjusted for population, the fatality rate is 42.9 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.

Despite a comparatively active crash history (111 recorded crashes), individual cause-code breakdowns are not published for Clarendon County in the current FARS release, so readers looking for contributing-factor data should use the South Carolina 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 Clarendon County is stable, meaning annual counts have stayed within a narrow band relative to the average. Residents, insurers, and policy analysts can use this baseline alongside population density, highway mile data, and rural-versus-urban road mix to judge whether Clarendon County's 120-death total is proportionate to its exposure. All numbers are for research and informational use only.
