While 55% of online teens have created a profile, not all of these profiles are visible to the entire internet at large. More than three out of four (77%) teens who have created profiles say that their profile is currently visible online, while 21% say their profile is not currently visible. Of those users who have viewable online profiles, more than half (59%) say that their profile is visible only to their friends. Another 40% say that their profile is visible to anyone who happens upon it online. Just 1% of social network users say they do not know who can see their profile.
