We should consider ourselves lucky to witness the transition between the industrial age and the information age in the past decade. The world came closer, thanks to internet, email, IMs and finally the social networks. Facebook has been continuously mapping various trends and patterns in the way people interact with each other and has shared with us fascinating results.

Degrees of separation

Social psychologists in 1929 stated that a person is linked with everyone on earth by not more than 6 relationships, the concept commonly referred to as ’6 degrees of separation’. Considering 721 million active users & 69 billion mutual friend relations, Facebook has been able to calculate the exact degree of separation (for the year 2011), which is 4.74. Exponential increase is apparent because it was just 5.28 in 2008.

Facebook affirms,

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. When we limit our analysis to a single country, be it the US, Sweden, Italy, or any other, we find that the world gets even smaller, and most pairs of people are only separated by 3 degrees (4 hops).

About time we rephrase ‘It’s a small world’ to ‘It’s a tiny world’. :)
