Smartwatches and fitness trackers are now worn by 1 in every 5 Americans

A new survey by the Pew Research Center (via 9to5Mac) found that 21% of American adults wears either a smartwatch or some other form of fitness tracking device.

Predictably, income and education – both potentially linked – are big indicators as to whether someone wears a smartwatch or fitness tracker, with almost a third of those in homes earning more than $75,000 per year wearing a device.

As is true with many other forms of digital technology, use of these devices varies substantially by socioeconomic factors. Around three-in-ten Americans living in households earning $75,000 or more a year (31%) say they wear a smart watch or fitness tracker on a regular basis, compared with 12% of those whose annual household income falls below $30,000. Differences by education follow a similar pattern, with college graduates adopting these devices at higher rates than those who have a high school education or less.

Gender, race, and ethnicity also saw differences in whether someone wears a device or not, although there wasn't as large of a divide.

There are more modest differences by gender and race and ethnicity. Women are more likely than men to say they regularly use these devices (25% vs. 18%). Hispanic adults are more likely than whites to report regularly wearing a fitness tracker (26% vs. 20%), while black adults fall in between at 23%.

Interestingly, it appeared that people who wore devices that tracked their health were more likely to want their health data to be shared with researchers than those who don't.

In addition, Americans who use fitness trackers are far more supportive of sharing data from these devices with health researchers than those who don't use these devices. Roughly half of users of fitness trackers (53%) say this is acceptable, compared with 38% of those who do not use fitness trackers.

For its part, Apple continues to dominate the wearables industry, of which Apple Watch is part. When narrowed down to just smartwatches, it's difficult to look past Apple Watch at all.
