NEW YORK — Facebook, it turns out, isn't just a waste of time. People who use it have more close friends, get more social support and report being more politically engaged than those who aren't, according to a new national study on Americans and social networks.
The report comes as Facebook, Twitter and even the buttoned-up, career-oriented LinkedIn continue to engrain themselves in our daily lives and change the way we interact with friends, co-workers and long-lost high school buddies.
Released Thursday by the Pew Internet and American Life Project, the report also found that Facebook users are more trusting than their non-networked counterparts.
When accounting for all other factors — such as age, education level or race — Facebook users were 43 percent more likely than other Internet users to say that "most people can be trusted." Compared with people who don't use the Internet at all, Facebook users were three times more trusting.
The reason for this is not entirely clear. One possible explanation: People on social networks are more willing to trust others because they interact with a larger number of people in a more diverse setting, said Keith Hampton, the main author of the study and a communications professor at the University of Pennsylvania.
AT A GLANCE
Some findings from a study on social networks from the Pew Internet and American Life Project:
- Social networks are more prevalent than ever. Among U.S. Internet users, 59 percent use at least one social network. That's up from 34 percent in 2008.
- LinkedIn users tend to be older, male and more educated.
- Perhaps for this reason, LinkedIn are much more likely to be politically engaged than users of other social networks.
- MySpace users, who tend to be younger and less educated, are the least politically active among all social-networking users.
- When accounting for the demographic differences, however, Facebook users are more politically engaged than people who are not on Facebook.
- People who use MySpace are more likely to be open to viewpoints they disagree with, after accounting for all other demographic factors.
- 92 percent of social network users are on Facebook, 29 percent use MySpace, 18 percent use LinkedIn and 13 percent use Twitter.
- 52 percent of Facebook users use it daily, compared with 33 percent of Twitter users, 7 percent of MySpace and 6 percent of LinkedIn users.
- Clicking "like" on another user's content is the most common activity on Facebook. "It's pretty non-committal, the lightest thing you can do," said Keith Hampton, the study's main author. It signals to people that you know they are out there, that you are aware of them.
When all else is equal, people who use Facebook also have 9 percent more close ties in their overall social network than other Internet users. This backs an earlier report from Pew that, contrary to studies done earlier in the decade, the Internet is not linked to social isolation. Rather, it can lead to larger, more diverse social networks.
Social-networking users also scored high in political engagement. Because LinkedIn users (older, male and more educated) fall into a demographic category that's more politically active than the general population, they were most likely to vote or attend political rallies. But after adjusting for those characteristics, Facebook users, especially those who use the site multiple times a day, turned out to be more politically involved than those who don't use it.
Overall, the average American has a little more than two close confidants, 2.16 to be exact, according to the report. This is up from an average of 1.93 close ties that Americans reported having in 2008. There are also fewer lonely people: 9 percent of respondents said they had no one with whom they could discuss important matters. That's down from 12 percent in 2008.
The report didn't try to dig into cause and effect, so it's not clear whether the widening use of social networks is causing less loneliness. But it did find that people who use the Internet are less socially isolated than those who don't. Those on social networks, even less so — just 5 percent said they had no one to talk to about important stuff.
The researchers also got numbers to back up what's in the mind of many Facebook users past a certain age: Yes, all your old high school classmates really are coming out of the woodwork and "friending" you. The average Facebook user has 56 friends on the site from high school. That's far more than any other social group, including extended family, co-workers or college classmates.
Facebook's settings let users add the high school they attended to their profile, along with the year they graduated. Other users can then search for their classmates and add them as friends for a virtual reunion.
"It's really reshaping how people maintain their networks," Hampton said.
In the past, when people went to college or got jobs and moved away from their home towns, they left those relationships behind, too. This was especially true in the 1960s, when women not in the work force would move to the suburbs with their husbands and face a great deal of isolation, Hampton said.
Now, with social networks, these ties are persistent.
"Persistent and pervasive," Hampton said. "They stay with you forever."
The survey was conducted among 2,255 adults from Oct. 20 to Nov. 28, 2010. The margin of error is plus or minus 2.3 percentage points for the full sample.
