There are on average 3.74 degrees of separation between any one Facebook user and another, a study suggests.

The number of degrees represents the number of people in a friendship chain, excluding the people at either end.

Or, as the authors put it: "When considering another person in the world, a friend of your friend knows a friend of their friend."

The world is even smaller than you thought.

Adding a new chapter to the research that cemented the phrase "six degrees of separation" into the language, scientists at Facebook and the University of Milan reported on Monday that the average number of acquaintances separating any two people in the world was not six but 4.74.

The original "six degrees" finding, published in 1967 by the psychologist Stanley Milgram, was drawn from 296 volunteers who were asked to send a message by postcard, through friends and then friends of friends, to a specific person in a Boston suburb.

Facebook's Data Team says researchers used state-of-the-art algorithms to approximate the number of "hops" between all pairs of individuals on Facebook.
