Eman Yasser Daraghmi and Shyan-Ming Yuan, of the National Chiao Tung University in Taiwan, created a database on Facebook that included 950 million people. After eliminating duplicate/fake accounts as well as celebrities, they used advanced statistical methods to calculate how far everyone was spread out on the network. It was discovered that most individuals are connected in an average of four, however if you work or are engaged in more specialized circles or groups (such as medical or scientific research etc.), the number gets even lower.
