Despite a comparatively active crash history (69 recorded crashes), individual cause-code breakdowns are not published for Cass County in the current FARS release, so readers looking for contributing-factor data should use the North Dakota 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 Cass 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 Cass County's 75-death total is proportionate to its exposure.
