My October 13, 2005 post at Toledo Talk that excerpted a study:
Sixty-eight percent of American adults, or about 137 million people, use the internet, up from 63% one year ago. Thirty-two percent of American adults, or about 65 million people, do not go online, and it is not always by choice. One in five American adults say they have never used the internet or email and do not live in an internet-connected household. At the other end of the spectrum, 53% of home internet users have high-speed access, creating a new divide among internet users. 26% of Americans age 65 and older go online, compared with 67% of those age 50- 64, 80% of those age 30-49, and 84% of those age 18-29.
