Some 74 percent of U.S. adults go online, and more than half of those use broadband at home, according to a Harris Interactive survey released Thursday, InternetWeek reports. Fifty-four percent of online adults said they accessed the internet over broadband at home, compared with 37 percent in December of 2003.

Five years ago, 57 percent of U.S. adults were online. As of April, the number of adults online had reached 163 million, Harris said.

Adults accessing the internet at home and at work increased 1 percent and 2 percent, respectively, to 66 percent and 36 percent. Adults who are online at libraries, schools and other places rose to 21 percent from 17 percent in 2004. Internet penetration remains highest among younger and more affluent adults.
