Facebook: On the Road to 200 million Users

As we learned last week, Facebook has been growing worldwide ever since it began as a private network at Harvard in 2003. From 2004 to early 2006, the Facebook user base was all students, but ever since Facebook opened up to anyone with an email address the social networking site has been attracting an older crowd too. The fastest-growing group is now people over 35. This graphic from Lee Byron of the Facebook data team shows this worldwide growth along with interactions among an example user's network.
