Where people have the most and least health insurance coverage

While health insurance can prevent emergencies and catastrophic conditions from decimating your financial plans, the premiums and out-of-pocket expenses can also take a toll on your wallet. In 2024, the average annual premium for a single individual was nearly $9,000—and an estimated $25,500 for a family of four. While many workplaces subsidize these premiums, and the Affordable Care Act opened access to health care for Americans not covered by employer plans, health insurance is still often a costly budget item that some individuals may forgo. In these cases, Americans may be making tradeoffs between their health and their financial well-being.

With this in mind, SmartAsset ranked 810 U.S. counties based on the rate of people under age 65 who were insured in 2024. Annual changes in coverage, coverage of children, and the relative presence of primary care physicians in each county are also examined.
