Aaron Smith reports at Pew:
Roughly three-quarters of Americans (77%) now own a smartphone, with lower-income Americans and those ages 50 and older exhibiting a sharp uptick in ownership over the past year, according a Pew Research Center survey conducted in November 2016. Smartphone adoption has more than doubled since the Center began surveying on this topic in 2011: That year, 35% of Americans reported that they owned a smartphone of some kind.
When the Center started tracking social media adoption in 2005, just 5% of Americans said they used these platforms. Today, 69% of U.S. adults are social media users.
When the Center first began tracking tablet ownership in 2010, just 3% of Americans owned a tablet of some kind. That figure has risen to 51% as of November 2016.
