About Health in Jefferson County, Missouri
Jefferson beats national health averages
Jefferson County's 75.0-year life expectancy edges closer to the U.S. average of 78.9 years—though still a meaningful 3.9-year gap remains. Just 17.6% of residents report poor or fair health, significantly better than the national average. Jefferson emerges as one of Missouri's healthier counties relative to broader U.S. trends.
Jefferson ranks well within Missouri
At 75.0 years, Jefferson's life expectancy exceeds Missouri's 74.3-year state average by 0.7 years, placing it solidly in the upper half statewide. With only 17.6% of residents in poor or fair health—the lowest rate among these eight counties—Jefferson demonstrates stronger population health outcomes. The county's low uninsured rate (9.5%) underscores better access than most of the state.
Jefferson leads regional health metrics
Jefferson's 75.0-year life expectancy matches Lafayette County (74.9 years) and exceeds Jasper (73.8 years) and Lawrence (73.6 years) by 1-2 years. Its 17.6% poor/fair health rate is the best among regional peers, including Johnson County (17.5%, nearly tied). This consistency suggests Jefferson has created more stable health conditions across its population.
Coverage is strong, but provider gaps exist
Jefferson's 9.5% uninsured rate is well below Missouri's 12.5% average, indicating stronger insurance uptake across the county. However, with just 26 primary care providers per 100,000 residents, access to routine care may involve longer waits or travel, despite adequate mental health services (116 per 100K). This suggests Jefferson residents' good insurance coverage doesn't guarantee quick appointments with family doctors.
Maintain your coverage to stay healthy
If you're uninsured or between jobs, Jefferson's strong insurance baseline means help is likely available through employer plans, Medicaid, or marketplace options. Visit Healthcare.gov to compare plans, or contact a local benefits counselor to protect your coverage. Keeping insurance steady helps you access those primary care providers and avoid gaps in preventive care.
