What the Data Shows

St. Martin County, Louisiana recorded 106 total road fatalities across 96 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 17 deaths on county roads, and the annual average works out to approximately 11.8 fatalities per year. Adjusted for population, the fatality rate is 23.1 per 100,000 residents, which leaves it more dangerous than most U.S. counties by that per-capita measure among the 3,137 U.S. counties in this dataset.

Despite a comparatively active crash history (96 recorded crashes), individual cause-code breakdowns are not published for St. Martin County in the current FARS release, so readers looking for contributing-factor data should use the Louisiana 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 St. Martin 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 St. Martin County's 106-death total is proportionate to its exposure. All numbers are for research and informational use only.
