The notion of six degrees of separation between any two people stems from a 1929 short story, Chains, by Hungarian author Frigyes Karinthy and research performed in in the 1960s by American social psychologist Stanley Milgram. "We found that 84 per cent of all connections are between users in the same country," they said.įor the study done earlier this year, the researchers examined 721 million active Facebook users - a figure that represents more than 10 per cent of the global population - and the 69 billion friendships among them. The researchers said that when focusing on a single country, most pairs of people are separated by only three degrees, or four hops, and the vast majority of connections span only a short distance. "Thus, when considering even the most distant Facebook user in the Siberian tundra or the Peruvian rainforest, a friend of your friend probably knows a friend of their friend." The average distance in 2008 was 5.28 hops, while now it is 4.74. ![]() "As Facebook has grown over the years, representing an ever larger fraction of the global population, it has become steadily more connected. "Six degrees actually overstates the number of links between typical pairs of users. "We found that the degrees of separation between any two Facebook users is smaller than the commonly cited six degrees, and has been shrinking over the past three years as Facebook has grown," they said. Six Degrees of Kevin Bacon may be the name of the game but it takes less than that to connect any two users on Facebook.Īccording to a study by Facebook and the University of Milan, the average number of steps it takes to link any two individuals on the social network is 4.74.įacebook's Data Team says researchers used state-of-the-art algorithms to approximate the number of "hops" between all pairs of individuals on Facebook. ![]()
