A study released Friday by the Pew Research Center’s Internet and American Life Project finds that when it comes to social networks, women tend to be a lot less friendly than men.

Overall, “de-friending” people on sites like Facebook is up 56 percent from just two years ago — and women are doing most of it. “Some 67 percent of women who maintain a profile say they have deleted people from their network, compared with 58 percent of men,” the report states.

In addition, the fairer sex is more secretive, with 67 percent of them saying they’d set their profiles to “private,” something less than half of men have done.

Other report findings:

  • Younger people between 18 and 29 are more likely to de-friend than those between 30 and 49
  • Men are nearly twice as likely as women to have posted content online that they later regret
  • People with the highest levels of education reported having the most difficulty figuring out their privacy settings
  • 93 percent of social network users surveyed said they have a profile on Facebook, up from 73 percent in 2009
  • Fewer people use MySpace now — 23 percent of social network users said they have a profile on the site, down from 48 percent in 2009
  • 11 percent of social network users have Twitter accounts, a five percent increase from two years ago
