A new Department of Commerce study shows that sixty-four percent of all US households now have broadband Internet connections. Twenty-three percent of all US households report that no one in the home uses the Internet anywhere. Therefore, we can assume the remaining thirteen percent either use dial-up at home or else use the Internet elsewhere, such as at school, in a library, or at the office.
Ignoring those who do not use the Internet at all, we can deduce that less than one in five Internet users is still using dial-up. (Less than 13% of all American households versus 64%.)
Other findings include:
Seven out of ten American households used the Internet in 2009. The majority of these households used broadband services to access the Internet at home. Almost one-fourth of all households, however, did not have an Internet user.
Income and education are strongly associated with broadband Internet use at home but are not the sole determinants.
Broadband Internet adoption was higher among White households than among Black and Hispanic households in 2009. Differences in socio-economic attributes do not explain the entire gap in broadband Internet adoption associated with race and ethnicity.
Urban residents were more likely than their rural counterparts to adopt broadband Internet, even after accounting for socio-economic differences.
Home broadband Internet use by people with disabilities lagged adoption by those with no disability. Differences in socio-economic and geographic characteristics explain a substantial portion of the adoption gap associated with disability.
