Is Facebook Increasing The Size Of Our Personal Networks? Facebook Reveals The Answer

The Facebook data team has published an interesting note about some research they’ve conducted which explores whether or not Facebook is in fact increasing the size of our networks. While Facebook has become an extremely efficient communication tool, does it help us stay in contact better with our existing contacts or is it more efficient at expanding our networks? The results are interesting. According to Facebook, “while the average Facebook user communicates with a small subset of their entire friend network, they maintain relationships with a group two times the size of this core.”

The report details a number of other interesting statistics. For example, the average number of friends on Facebook for any given user remains at around 120, which is relatively close the much cited Dunbar number. The research also finds that an individual’s core network of friends that they “can discuss important matters” with “numbers only 3 for Americans.” In Keith Ferazzi’s latest book “Who’s got your back” he highlights how critical these relationships can be, and how essential they are to any individual’s success.
