The median lifespan in the United States today is nearly 79 years. Like all medians and averages, your mileage may vary. In some U.S. towns and cities, the median falls to around 68, and in others, it rises to more than 85.

What’s different? It’s not just the air or the scenery. According to a report from Realtor.com, the road to a longer lifespan is not the same everywhere, but there are commonalities such as veggie-rich diets and plenty of exercise.

Dan Buettner, founder of a movement called Blue Zones that helps communities set policies to help residents live longer, comments, “If you want to live a long time, the best thing you can do is move to a place where people are verifiably living the longest.”

To come up with their list of U.S. counties where residents live the longest, researchers looked at death certificates in every U.S. country for 2014 to calculate life expectancy from birth. In the following longevity list, they’ve added population data for a notable city in the county and the median home listing price.
