Pew Report on Generational Differences in Online Activity
Just released, Generations Online in 2009, from Pew Intenet & American Life Project. This report tracks internet use across generations.
From the Report's Overview:
"...the biggest online trend is that, while the very youngest and oldest cohorts may differ, certain key internet uses are becoming more uniformly popular across all age groups. These online activities include seeking health information, purchasing products, making travel reservations, and downloading podcasts.
Even in areas that are still dominated by Millennials, older generations are making notable gains. While the youngest generations are still significantly more likely to use social network sites, the fastest growth has come from internet users 74 and older: social network site usage for this oldest cohort has quadrupled since 2008, from 4% to 16%.
The primary adult data in this report is based on the findings of a daily tracking survey on Americans' use of the Internet. The results in this report are based on data from telephone interviews conducted by Princeton Survey Research Associates International between April 29 and May 30, 2010, among a sample of 2,252 adults ages 18 and older, including 744 reached on a cell phone. Interviews were conducted in English."
