US Internet users ages 10 to 15 flocked to social networks last year as if getting a MySpace account would increase their allowances.
Harris Interactive said in its April 2008 issue of Youth Trends that more than half of US girls ages 13 to 15 used social networking Websites in 2007, roughly the same as in 2006.
Social networking jumped among other boys and girls surveyed: more than twice as many children ages 10 to 12 reported using social networking sites in 2007 as did in 2006.
US teen girls reported similar high social network usage in a study by the Pew Internet and American Life Project and the National Commission on Writing conducted from September to November 2007.
As noted previously, technology plays a
significant role in communication for US teen girls, and this is a significant factor in their increasing use of social networks.
eMarketer estimates that 17.7 million US teens will use social networks in 2011, up from 13.6 million in 2007.
