Oh My Gov reports that the Pew Research Center found that only 9 percent of Americans responded to their surveys, but they are successfully using social media to improve their sample size.
Using this additional data allows researchers to pull information and insight from a larger audience of people who are interacting in natural ways without the influence of outside enticements. In fact, when considering the sheer number of people active in various online forums, there exists a real case for social media analysis as a critical supplement to other forms of opinion polling.
The majority of plugged-in Americans spend most of their Internet time on social networks and blogs, engaging in everything from reading to commenting to posting their own articles and opinions. Though 1 in 5 adults in the United States aren't online, the 80% who are make use of Facebook, Twitter, and other networking sites on a regular basis, and more people connect each year.
For example, Facebook saw a dip in younger users last year, but the number of voting-age participants increased significantly.
Late 2011 research revealed that more than half of all users had shared political content on Facebook. Influential 18-34 year-olds also make up the largest demographic on Twitter, where they are prone to sharing political opinions and debate.
