About Health in St. Clair County, Missouri
St. Clair faces above-average health challenges
At 75.0 years, St. Clair's life expectancy falls slightly below the U.S. average of 74.5 years, and 22.1% of adults report poor or fair health, exceeding the national rate of 21%. These figures suggest St. Clair residents experience chronic illness and premature mortality at rates slightly worse than the American norm.
St. Clair ranks below Missouri's middle tier
St. Clair's 75.0-year life expectancy is 0.7 years below Missouri's state average of 74.3 years, placing it in the lower half of the state's counties. The uninsured rate of 12.3% closely mirrors Missouri's 12.5% average, indicating standard access barriers for the region.
St. Clair trails healthier neighbors
St. Clair's 75.0-year life expectancy lags Ste. Genevieve (76.5) by 1.5 years and St. Louis County (76.3) by 1.3 years, though it exceeds St. Francois (71.9). With 43 primary care providers and 31 mental health providers per 100K, St. Clair has moderate but not abundant healthcare capacity compared to wealthier neighbors.
Limited mental health services strain residents
St. Clair has 43 primary care providers per 100K, offering reasonable access to routine medicine, but only 31 mental health providers per 100K—a gap that may force residents to travel for behavioral health care. With 12.3% uninsured, cost barriers likely compound delays in both primary and mental health treatment.
