Why your friends have more friends than you?: the “friendship paradox”

NEW YORK – Do you know what the “friendship paradox” is? Have you ever wondered why your friends have more friends than you do?

In a article of the New York Times Steven Strongatz explained this:

“When it comes to friendship and social networks, popular friends “contribute disproportionately to the average, since besides [having more friends], they’re named as friends more frequently.” Strogatz cites a recent study that examined 721 million Facebook users and found that a user’s friend count was less than the average friend count of his/her friends 93 percent of the time. The theory is that the average number of “friends of friends” will always be greater than the average number of friends of individuals, because the more popular people are counted more than once.”
