What the Data Shows

Darlington County, South Carolina recorded 166 total road fatalities across 154 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 27 deaths on county roads, and the annual average works out to approximately 18.4 fatalities per year. Adjusted for population, the fatality rate is 29.5 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 (154 recorded crashes), individual cause-code breakdowns are not published for Darlington 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 Darlington 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 Darlington County's 166-death total is proportionate to its exposure.
