Younger users of social networking sites, when compared to older users of those same sites, are more likely to try to limit how much information about them is made available publicly, according to a new survey released today by the Pew Research Center’s Internet and American Life Project. The poll of 2,253 adults shows that 71 percent of those aged 18-29 have changed the privacy settings on their profile to limit the information shared with others, compared to 55 percent of those aged 50-64. “Contrary to the popular perception that younger users embrace a laissez-faire attitude about their online reputations, younger adults are often more vigilant than older adults when it comes to managing their online identities,” said Mary Madden, a senior research specialist with Pew.
