Two Pew Internet Project surveys of teens and adults reveal a decline in blogging among teens and young adults and a modest rise among adults 30 and older. In 2006, 28% of teens ages 12-17 and young adults ages 18-29 were bloggers, but by 2009 the numbers had dropped to 14% of teens and 15% of young adults.
Much of the drop in blogging among younger internet users may be attributable to changes in social network use by teens and young adults. Nearly three quarters (73%) of online teens and an equal number (72%) of young adults use social network sites. By contrast, older adults have not kept pace; some 40% of adults 30 and older use the social sites in the fall of 2009.
However, even as blogging declines among those under 30, wireless connectivity continues to rise in this age group.
New survey results also show that among adults 18 and older, Facebook has taken over as the social network of choice; 73% of adult profile owners use Facebook, 48% have a profile on MySpace and 14% use LinkedIn.
