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 Linn 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 Linn County's 131-death total is proportionate to its exposure.
