The share of U.S. adults who say they own a smartphone continues to increase year over year, from just 35% of adults in 2011, to 77% in 2018 and 81% in 2019. Reliance on smartphones to access the internet has also increased steadily over the past few years. Since 2013, the amount of “smartphone only” internet users has doubled from 8% to 17% of Americans, and those citing smartphones as their primary device for going online has increased from 19% to 37% over the same timeframe. While smartphone ownership does vary by age group, it is widely adopted across different economic, educational, and ethnic demographic groups.
