The next several years will continue to see double-digit growth in the number of Americans using wearable devices, according to eMarketer's first wearables forecast. In 2015, 39.5 million US adults 18 and over will use wearables, including smartwatches and fitness trackers. That's a jump of 57.7% over 2014. While penetration among US adults is just 16.0% this year, eMarketer expects that to double by 2018, to 81.7 million users.
eMarketer defines wearable users as those who wear accessories or clothing at least once per month that are embedded with internet-connected electronics and exchange data with a manufacturer or other connected device.
Wearables are currently most popular among US adults between 25 and 44, who are the most involved in the movement toward data and fitness tracking. In 2015, 25.1% of internet users between 25 and 34 and 23.1% of those between 35 and 44 will use one. By 2018, 49.9% of 25- to 34-year-old internet users and 47.0% of 35- to 44-year-old internet users will use a wearable device.
Long-term, older Americans are expected to be a bigger growth driver, as more wearable health monitoring devices hit the market. Throughout the forecast period, US adults 65 and older will see the biggest growth rates every year for wearable adoption....
Almost two in five internet users will use wearables by 2019. Huge potential.
