A survey by the Pew Research Center’s Internet & American Life Project looked at people’s general use of SNS for politics and about the ways in which they interact with friends on the sites over political material.
Overall, the survey found that 80% of American adults use the internet and 66% of those online adults participate in social networking sites (SNS) such as Facebook, LinkedIn, or Google+. That amounts to more than half of the entire U.S. population who are SNS users.
Those who describe their political beliefs as moderate or liberal are more likely than conservatives to use social networking sites: 74% of internet users who describe themselves as liberal use SNS and 70% of internet users who are moderate are SNS users —that compares with 60% of conservative internet users who are SNS users. The chart below shows what proportion of the entire population — not just internet users — falls into these categories.
There were no statistically significant differences among Democrats, Republicans, and independents in their overall use of SNS. All were equally likely at least to be social networking site users.
