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 Coos County is decreasing, which suggests that road-design improvements, enforcement, or emergency-response changes are reducing the death toll. Residents, insurers, and policy analysts can use this baseline alongside population density, highway mile data, and rural-versus-urban road mix to judge whether Coos County's 44-death total is proportionate to its exposure.
