34 Of The Healthiest Counties In America

The United States lags behind many other wealthy, highly developed countries in key public health indicators. According to a report published by the World Obesity Federation, a London-based non-profit advocacy group, the adult obesity rate in the U.S. was nearly 43% in 2022, higher than in all but a handful of high-income countries, and more than double the obesity rate in France, Germany, Italy, Switzerland, and across Scandinavia. Additionally, 2023 data from the World Bank shows that average life expectancy at birth in the U.S. is just 78.4 years, well below the 80-plus-year average in places like Canada, the European Union, Japan, South Korea, and the United Kingdom.

Explanations for America’s lagging health indicators are complex and linked to a number of social, economic, and systemic factors. Insufficient investment in health care, however, is not one of them. At $12,434 in 2022, the United States spends more per capita on health than any other country in the world. But despite unparalleled spending, the United States does not have a universal health care system, making treatment or regular preventative care unaffordable for millions of uninsured Americans. Other commonly cited factors, often interconnected with individual economic circumstances and lifestyle choices, include poverty, poor diets, limited physical activity, violence, and drug abuse.

Although public health challenges are widespread and deeply entrenched in America, some parts of the country stand out for exceptionally strong health outcomes.

Using data from County Health Rankings and Roadmaps, a program of the University of Wisconsin Population Health Institute, 24/7 Wall St. identified the healthiest counties in America. Counties and county equivalents are ranked on an index of four health outcome measures: years of potential life lost before age 75 for every 100,000 people, average number of mentally unhealthy days per month, average number of physically unhealthy days per month, and the share of adults who report being in fair or poor health. All supplemental data on smoking rates, uninsured rates, physical inactivity, income, and population size are also from CHR.

Of the 34 counties on this list, most are in the Midwest, including six in South Dakota and four in Iowa. Another seven counties are in the South, six are in Western states, and three are in the Northeast. Average life expectancies at birth in many of these places are among the highest in the country, ranging from 78.3 years to 94.2 years. Adults in these counties are also far more likely than a typical American to report being in good health and to experience fewer physically or mentally unhealthy days.

Strong health outcomes in these areas are likely due in part to several underlying factors. For example, in most of these counties, more than four in every five adults report regular exercise. Additionally, in a majority of places on this list, rates of cigarette smoking — the leading preventable cause of disease, death, and disability in the United States — are in the lowest 10th percentile of all U.S. counties.

Residents of many of these places are also more likely to be able to afford regular preventative health care than a typical American. In all but six counties on this list, the share of residents without health insurance is below the 10% national uninsured rate. Additionally, the median household income in most of these counties exceeds the national median by tens of thousands of dollars. 

These are the healthiest counties in America. 

Why It Matters

The United States spends more per capita on health care than any other country in the world. Still, Americans tend to live shorter, less healthy lives than those in most other wealthy, highly-developed countries. While the United States lags behind other similar countries in key outcome measures, some American communities at the local level stand out for having exceptionally healthy populations, as reflected in both objective and self-reported indicators.
