You Are Just 4.74 Steps Away From Everyone on Facebook

25 Nov

Facebook is shaking up the common theory of six degrees of separation.

An analysis of Facebook’s 721 million members has revealed that you are connected to any one member on Facebook via a maximum average of 4.74 hops. Really?

This part of  information is shared from a lengthy post called on Facebook’s Anatomy of Facebook data blog. The study is the most comprehensive so far, reaching  statistically, more than 10 percent of the world’s population. Facebook also noticed that 69 billion friendships were evaluated. The result that there are fewer than previously expected jumps between users is based on the finding that, only 10 percent of people have less than 10 friends, 20 percent have less than 25 friends and 50 percent have over 100 friends. The average number of friends is 190.

If all those friend relations are connected, Facebook discovered that though 99.6 percent of all friendship pairs are connected by paths with 5 degrees (6 hops), 92 percent are connected by only four degrees (5 hops). Not surprisingly, as we get more connected, the number of hops is decreasing: The average distance in 2008 was 5.28 hops, now it is at 4.74.

This number may make us feel somewhat strange, at least if one use the word “friendship” connections. Is any person on this globe only 4.74 friendship hops away? No. Perhaps we should consider them contact hops, but not friendship hops. Many of us may have contacts who have collected thousands of “friends” and may serve as distribution pillars of contacts. What’s more, we all may have contacts we really don’t know or never interacted with.
