Pew Internet Project data is quoted in an AP story about how John McCain is not a frequent internet user, so I thought I'd highlight some sources for people who want to explore the numbers for themselves:

Home Broadband 2008 (report based on April-May 2008 survey data, which is quoted in the AP story)

check out the chart on p. 3 to see home broadband access trends among various demographic groups for the last 4 years

check out the chart on p. 13 to see the demographic profiles for home broadband, home dial-up, and non-internet users (median age for home broadband = 40; median age for dial-up = 45; median age for non-users = 61)

Who's Online (our fall 2007 survey data)

Internet Activities (our fall 2007 survey data)

displays a list of online pursuits ranked by popularity

Generations Online (report based on 2005 data, not to be confused with Generations on Line, which provides internet training and tips for older adults)

check out the chart on p. 3 to see the popularity of internet activities among various age groups

And, of course, we have data about The Internet and the 2008 Election
