Teens and Mobile Phones Over the Past Five Years: Pew Internet Looks Back, August 2009: “Teenagers have previously lagged behind adults in their ownership of cell phones, but several years of survey data collected by the Pew Internet & American Life Project show that those ages 12-17 are closing the gap in cell phone ownership. The Project first began surveying teenagers about their mobile phones in its 2004 Teens and Parents project when a survey showed that 45% of teens had a cell phone. Since that time, mobile phone use has climbed steadily among teens ages 12 to 17 – to 63% in fall of 2006 to 71% in early 2008. In comparison, 77% of all adults (and 88% of parents) had a cell phone or other mobile device at a similar point in 2008.”
