# How you are connected to everyone on Facebook by 3.5 people

Facebook has calculated how connected the world is in honour of Friends Day.

The company took its 1.59 billion users and worked out that each person is connected to every other person by an average of three and a half other people.

You can see your “degrees of separation” rating on Facebook’s Research page.

“The average distance we observe is 4.57, corresponding to 3.57 intermediaries or “degrees of separation.” Within the US, people are connected to each other by an average of 3.46 degrees,” said Facebook.

The majority of people on Facebook have averages between 2.9 and 4.2 degrees of separation, as shown in the graph below.

“Imagine a person with 100 friends. If each of his friends also has 100 friends, then the number of friends-of-friends will be 10,000. If each of those friends-of-friends also has 100 friends then the number of friends-of-friends-of-friends will be 1,000,000.”

“Some of those friends may overlap, so we need to filter down to the unique connections. We’re only two hops away and the number is already big.”

“In reality this number grows even faster since most people on Facebook have more than 100 friends.”
