Data Story
About Health in Knox County, Maine
Knox leads national life expectancy
At 78.9 years, Knox residents live 2.5 years longer than the U.S. average of 76.4 years, placing the county in America's top tier for longevity. Only 12.4% report poor or fair health, matching Cumberland County's elite standard and far exceeding national norms. These figures reflect a coastal Maine advantage in economic stability and health resources.
Second healthiest county in Maine
Knox's 78.9-year life expectancy ranks second in Maine, trailing only Cumberland County's 79.5 years and exceeding all other counties by significant margins. Its 12.4% poor/fair health rate ties Cumberland for the state's best, signaling exceptional population health. At 107 primary care providers per 100K, Knox delivers strong frontline care access.
Coastal health advantage evident
Knox's 78.9-year life expectancy rivals Lincoln County (78.8 years) and exceeds Hancock County (78.1 years), confirming a coastal Maine health advantage. Its 12.4% poor/fair health rate beats all three neighbors, positioning Knox as Maine's second-healthiest county. Yet its 10.3% uninsured rate exceeds both Lincoln (10.1%) and trails Hancock (11.5%), suggesting that strong community fundamentals buffer coverage gaps.
Strong health despite coverage challenges
Knox's 10.3% uninsured rate represents roughly 1 in 10 residents without health coverage, yet population health outcomes remain among Maine's strongest. The county provides 107 primary care providers per 100K and 549 mental health providers per 100K, supporting accessible, continuous care. Community stability and economic resilience appear to offset insurance gaps for many residents.
Close the final coverage gaps
While Knox County leads in health outcomes, the 10.3% of uninsured residents remain vulnerable to catastrophic medical costs. Visit maine.gov/dhhs or healthcare.gov to explore coverage that protects your family's financial and physical health. Even in a healthy county, insurance protection matters.
