National Geographic Awards Boulder #1 Happiest City in the US

National Geographic, bestselling author Dan Buettner, and Gallup’s social scientists teamed up to develop an index that assesses measurable expressions of happiness and identifies where Americans are living their best lives. Designed by Gallup senior scientist Dan Witters, the study established 15 metrics—from eating healthy and learning something new every day to civic engagement, financial security, vacation time, and even dental checkups—that signal happiness. The National Geographic Gallup Special/Blue Zones Index draws on nearly 250,000 interviews conducted with adults from 2014 to 2015 in 190 metropolitan areas across the U.S.

The winner: Boulder, Colorado. Bolstered by a sense of community, access to nature, sustainable urban development and preservation policies, and perhaps even that clean mountain air, Boulderites overwhelmingly feel “active and productive every day,” according to Buettner’s research. Per capita, more people walk to work in Boulder than in any other city in the U.S. Low rates of smoking and obesity, and high rates of exercise, contribute to the satisfaction locals feel. Life is not always rosy in the Rockies—stress is on the rise; on average, 49 percent of locals surveyed reported feeling stress—but the qualities that keep Boulder on top make this city America’s happiest.
