As per a Pew Internet Project’s report, titled “Social Media and Mobile Internet Use Among Teens and Young Adults,” while teenagers and young adults avidly use social-media sites like Facebook and MySpace, their use of blogging has plunged over the last three-year period.

The survey was part of a Pew Research Center series of studies which pertained to examining the behaviors, values, and opinions of the teenagers and Twenty-somethings – two groups that together comprise the Millennial Generation.

Going by the statistics of the report, the number of teenaged bloggers, aged 12-17 years, dropped from 28 percent in 2006 to nearly 14 percent by fall 2009; while the number of young adult bloggers, aged 18-29 years, plunged from 28 percent to 15 percent.

Meanwhile, during the same period, the percentage of adult bloggers, aged over 30 years, increased from 7 percent to 11 percent.

According to the survey, the fall in the popularity of blogging among younger Internet users has resulted from the changes in the way social network is being used. Going by the 2009 fall figures, approximately 73 percent of online teens and young adults use social-networking sites; while merely about 40 percent of adults over 30 years use these sites.

Commenting on the figures, the report’s co-author and Pew researcher Amanda Lenhart said: “Out of all the data, we think in some ways it's most surprising to see a decline in blogging.”
