Ten percent of American adults use a smartphone with a wireless mobile connection as a substitute for a broadband internet subscription
While 80 percent of U.S. adults have access to high-speed internet, ten percent have access only through a smartphone. This proportion is even higher among African Americans (15 percent), Hispanics (22 percent), and individuals with a high-school degree or less (14 percent). While universal broadband adoption is a good abstract goal, in practice smartphones have been much more effective in narrowing access gaps along income-lines and along racial and ethnic lines. Users with only smartphones only engage in 16 percent fewer activities online than do users with home broadband subscriptions.
