These are among the key findings from a new report based on a survey of 802 teens that examines teens’ privacy management on social media sites: 
 
 Teens are sharing more information about themselves on social media sites than they did in the past. Teens take other steps to shape their reputation, manage their networks, and mask information they don’t want others to know; 74% of teen social media users have deleted people from their network or friends list. Teens are sharing more information about themselves on social media sites than they did in the past. Teens are increasingly sharing personal information on social media sites, a trend that is likely driven by the evolution of the platforms teens use as well as changing norms around sharing. More than 90 percent of teen social media users said they have posted a picture of themselves _ up from 79 percent in 2006, the poll said. Seven in 10 disclose the city or town where they live, up from about 60 percent over the same time period. And 20 percent disclose their cell phone number _ up sharply from 2 percent in 2006. In what may be a concern to parents, more than 60 percent of the teens with Twitter accounts said their tweets were public, meaning anyone on Twitter _ friend, foe or stranger _ can see what they write and publish. About one-quarter of kids said their tweets were private, and 12 percent said they did not know whether their tweets were public or private. Teens are also sharing much more than in the past. Just over half the teens have deleted comments from others on their profile or account. Esquivel said he still checks his Facebook account daily but isn't using it as regularly. Teens who are concerned about third party access to their personal information are also more likely to engage in online reputation management. "They still have their Facebook profiles, but they spend less time on them and move to places like Twitter, Instagram and Tumblr." Among teen social media users, 57% said they had an experience online that made them feel good, compared with 30% of teen internet users who do not use social media. About the survey and focus groups 
 
 These findings are based on a nationally representative phone survey run by the Pew Research Center’s Internet & American Life Project of 802 parents and their 802 teens ages 12-17. The poll was conducted between July 26 and September 30, 2012, on landline and cell phones. The margin of error for the full sample is plus or minus 4.5 percentage points.
– The vast majority of teens (to the tune of 94% in 2012) are on Facebook, but many of them are gravitating toward Twitter and other social media sites that their parents don't tend to use, according to a new Pew Research Center poll. Researchers found that teenage Facebook users—70% of whom are "friends" with their parents—consider the site a necessary part of socializing, but are losing enthusiasm for it because of overzealous posters, the "drama," and the growing number of adults using Facebook. "They still have their Facebook profiles, but they spend less time on them and move to places like Twitter, Instagram, and Tumblr," one of the study's authors tells the AP. And while that aforementioned 94% figure is flat year-over-year, the 26% of teens on Twitter last year is more than double the 12% who used it in 2011. The study also found that teens are sharing a lot more about themselves on social media than in years past, with 90% having posted a picture of themselves, up from 79% in 2006, and 20% making their cell phone number public, up from just 2% in 2006. Only 9% of the teens polled said they were "very concerned" about third parties accessing their data.
