Critical health disparity in Idaho
Lewis County's 73.4-year life expectancy is a stark 4.1 years below Idaho's 77.5-year average, marking it as the state's lowest in this group. Its 11.3% uninsured rate aligns with state average, but provider scarcity compounds access problems.

Severe provider shortage, mixed coverage
Lewis County has only 27 primary care providers and 134 mental health providers per 100,000 residents—among Idaho's lowest. While 11.3% uninsured is near the state average, sparse providers mean residents struggle to get timely appointments even with coverage.
