Women in the 18-29 age range are the most fervent users of sites like LinkedIn and Facebook.

The number of adults using social networking sites has increased 61% since 2010, according to a Pew Research Center report.

The Pew Internet & American Life Project found that 65 percent of the 2, 277 adults surveyed say they use sites such as LinkedIn, Facebook or MySpace. That's more than double the percentage that reported social networking site usage in 2008 (29%).

Also, in a first for Pew Internet surveys, it means that half of all adults in the U.S. use social networking sites.

Mary Madden, co-author of the Pew report said, "The graying of social networking sites continues but the oldest users are still fare less likely to be making regular use of those tools.

"While seniors are testing the waters, many Baby Boomers are beginning to make a trip to the social media pool as part of their daily routine."

Among Internet users, social networking sites are most popular with women, young adults under age 30, and parents. Fully 89% of women in the 18-29 age range are social networkers and 69% of those do so on an average day.

Asked to describe their experience using social network sites, "good" was the most common response from survey respondents.
