Only 14% of teens ages 12-17 worked on their own blog as of 2009, a drastic decrease since 2006, when twice as many (28%) said they had done so. Millennials have also seen a decline in blogging over the past couple years, from 20% in December 2008 to 18% in May 2010. As previous Pew Internet research has noted, it is possible that status updates and other functions that are incorporated into increasingly-popular social network sites may be replacing stand-alone blogs for young people.

Yet while blogging is less common for internet users under 34, it has increased in popularity among most older generations. Blogging among members of Gen X increased from 10% in December 2008 to 16% in May 2010, and 11% of Younger and Older Boomers currently blog as well. The result is a slight increase in blogging for adults overall, from 11% in late 2008 to 14% in 2010.
