The study found that 65 million US households - 61% of the total - are now actively using the Internet, an increase of 8.4 million since November 2000. The survey defined active use as when one member of a surveyed household had accessed the Internet at least once during the 31 days prior to receiving the questionnaire.
Peggy Schoener, senior analyst for Dataquest's Telecommunications and Networking Group, said the majority of US consumers were persisting with dial-up connections, a medium which accounted for over 75% of all connections.
Schoener attributed the slow uptake of broadband to an industry focus on business accounts and roll-out problems with DSL technology, although the report highlighted that 20% of dial-up households planned to upgrade to broadband by the middle of next year.
A separate report last week found that US consumers were continuing to flock to e-commerce Web sites, increasing their total purchases from $3.2bn (£2.2bn) in June to $3.98bn (£2.74bn) in July.
