Where are Americans healthiest? The answer is different than you might think.
Which metropolitan area is America's healthiest? You might guess it's Los Angeles, what with all those washboard abs you see at Venice Beach, Santa Monica or Malibu. Or maybe Denver or Boulder, considering all the mountain biking, rock climbing and winter sports Colorado is famous for.
You'd be surprised. The fittest metro in America is Minneapolis-St. Paul, according to the annual American Fitness Index™ (AFI), just released by the American College of Sports Medicine (ACSM). The Twin Cities finished third last year; this year they pushed perennial winner Washington, DC into second place. Their winning rank reflects the cities' relatively low (and rapidly-diminishing) smoking rate, their above-average percentage of regular exercisers, moderate-to-low rates of obesity, asthma, diabetes, and other chronic concerns, and rising share of farmers' markets (indicative of a trend towards healthier dining). Boston takes the bronze, with Portland, Oregon fourth and Denver in fifth place. At the opposite end of the spectrum, Oklahoma City ranks as America's least fit metro, followed by Louisville, Memphis, Birmingham, and Detroit.
The AFI rates the
relative fitness of America's 50 largest metros based on data from the
U.S. Census, U.S. Centers for Disease Control and Prevention's
Behavioral Risk Factor Surveillance System (BRFSS), and The Trust for
Public Land City Park Facts, among other sources. The AFI takes both
personal health indicators (statistics on specific diseases, obesity,
smoking levels, etc.) and community and environmental factors (health
care access, community resources that promote fitness, etc.) into
The above map shows us which cities are fit and which are not so fit, but it doesn't tell us why that might be or what it reflects. So, with the help of my Martin Prosperity Institute colleague Charlotta Mellander, I took a quick look at the demographic, economic, and geographic factors that might be associated with better or worse fitness across metros. Correlation is not causation, of course--what we are looking at here are simply associations. But they are thought-provoking enough to suggest other avenues of research.
Many people think fitness is better in warmer locations. Not so much. Each of the top five metros is pretty chilly, and the top ranked Twin Cities are among the coldest locations in the United States--certainly compared to warm and sunny LA, which languishes in 41st place. Our analysis found no correlation between fitness and January temp and a negative correlation between fitness and July temperature (-.49).
Perhaps more to the point, fitter cities are also more affluent. There are considerable correlations between fitness and several measures of economic development including average wages (.56) average income (.47) and economic output (gross metro product) per capita. The scatter-graph above charts the trend for income.
Fitter cities are better educated. There is a close correlation between fitness and the share of adults with a college degree (.64), as the above chart shows.
Fitter cities are also more innovative. There are significant correlations between fitness and the concentration of high-tech industry (.42) and the level of innovation (measured as patents per capita, .48).
Fitness is associated with the kinds of work we do. Metros with a high
share of professional, technical and knowledge jobs are fitter (with a
correlation of .58), while those with working class jobs are less fit
(with a negative correlation of -.56)--see scatters above and below. A
paradox, perhaps, because working class people put more physical effort
into their jobs, but sedentary professionals are much more likely to
pursue vigorous exercise in their leisure time, while blue collar
workers dedicate their downtime to, well, leisure. Also, fitness shows
no correlation to hours worked. It does however show a modest
correlation to the unemployment rate (-.29).
Which brings me to the last chart (see above), which compares metros' rankings on the Fitness Index to their reported levels of well-being. Perhaps not surprising, the correlation (.71) is the highest of any variable in our analysis. To the chronically under-employed, their richer, thinner, happier neighbors must seem unbearably smug.
From The Biggest Loser to Oprah's documented struggles with her weight, fitness is a signal obsession of American popular culture. We suffer from no dearth of health, fitness, and nutritional experts; celebrities, politicians, and even first ladies exhort us to eat better, exercise more, and get fit. But we need to face up to the fact that healthy or unhealthy lifestyles are not simply the result of good or bad individual decisions. They are inextricably tied up with the nature and structure of our culture and society. America's increasingly uneven geography of fitness is perhaps the most visible symbol of its fundamental economic and class divide.
