Some 70% of American adults have a high-speed broadband connection at home; an additional 10% of Americans lack home broadband but do own a smartphone. And 20% of Americans have neither a home broadband connection nor a smartphone.
As of May 2013, 70% of American adults ages 18 and older have a high-speed broadband connection at home, according to a nationally representative survey by the Pew Research Center's American Life Project. This is a small but statistically significant rise from the 66% of adults who said they had home broadband in April 2012.
The demographic factors most correlated with home broadband adoption continue to be educational attainment, age, and household income. Almost nine in ten college graduates have high-speed internet at home, compared with just 37% of adults who have not completed high school. Similarly, adults under age 50 are more likely than older adults to have broadband at home, and those living in households earning at least $50,000 per year are more likely to have home broadband than those at lower income levels.
