It’s pretty accurate to say yoga has taken the country by storm. And the popularity of the practice is visible in lots of ways: in the sheer number of yoga studios in the U.S., in the amount of yoga gear that’s for sale at all kinds of retailers and even in the excited conversations about yoga and meditation practices you can overhear in public places, at least in big cities. But even more, it’s evident in people’s reasons for doing yoga. A new survey by Yoga Alliance and Yoga Journal (carried out by Ipsos Public Affairs), queried 2,000 people in the general population and 1,700 more yoga practitioners. The study set out to quantify the spread of yoga across the U.S. But it also looks atwho’s practicing yoga these days and the motivations people have for practicing. And interestingly, all of these elements have changed over the last few years, and will very likely to continue to evolve as well.
