Quantifying Political Discussion from the Universe of Facebook Status Updates

The Internet has fundamentally changed the way we conceptualize public opinion, even beyond the way it has altered the traditional measurement of public attitudes and behaviors using random sampling of the broader population. The data analyzed in this paper offer one of the first comprehensive evaluations of mass political discourse generated via messages posted publicly on Facebook (called “status updates”), and allow us to quantify political discussion on Facebook without relying on self-reported behavior, or data from a limited topical context or sample. We find that while less than 1% of the users who post status updates on Facebook on a given day post a political status update, discussion is remarkably responsive to real-world political events. We suggest that instead of thinking of social media data simply as a measurement tool, we re-conceptualize it as both a way to monitor public discourse and also as a driver of public opinion.
