A new report from U.S. News and World Report and Aetna found that Williamson County is the healthiest county in Tennessee, and among the healthiest in the U.S.
According to the report — which compiled data from sources like the Centers for Disease Control and Prevention, the U.S. Census Bureau and the Centers for Medicare and Medicaid Services — residents of Williamson County have a life expectancy of about 82 years.
About 15% of the population smokes and just more than 6% of the population doesn’t have health insurance. All of those metrics were better than the national median.
The report calculated scores for 10 different health categories. Williamson County scored the highest marks in the economy and community vitality categories, but scored lower marks in the food and nutrition and environment categories.
The county’s low poverty rate, about 4.4%, and high median income, more than $109,000, pushed up the score for the economy category. In the community vitality category, the county had a relatively high rate of home ownership and high number of nonprofit groups.
Williamson County had a relatively high rate of people without access to a large grocery store, pushing down the score for the food and nutrition category. The area’s hot summers and cold winters pulled down the score in the environment category.
With a total score of 80.3, Williamson County was far and away the healthiest county in Tennessee, according to the report. The second healthiest county in Tennessee was Wilson County, which had a score of 54.2.
In 2019, Williamson County ranked 22nd on the same list and ranked 21st in 2018.
