From Pew Research Center:
For many Americans, going online is an important way to connect with friends and family, shop, get news and search for information. Yet today, 10% of U.S. adults do not use the internet, according to a new Pew Research Center analysis of survey data.
The size of this group has changed little over the past four years, despite ongoing government and social service programs to encourage internet adoption in underserved areas. But that 10% figure is substantially lower than in 2000, when the Center first began to study the social impact of technology. That year, nearly half (48%) of American adults did not use the internet.
Internet non-adoption is linked to a number of demographic variables, including age, educational attainment, household income and community type, the Center's latest analysis finds.
