Facebook has just reached the impressive 500 million users mark, something to celebrate, share and like. Among their different initiatives to promote this success and to gain even more users, I've found this graphic by Facebakers to be very interesting, giving us a snapshot of Facebook's state.

The USA is clearly ahead of all other countries in number of users, with the UK coming in second place with a fifth of the users. Most of the users are over 24 years old and there's a half and half gender split, with a missing 3% that I wonder if it is made of un-sexed angels.

As a Spaniard living in Belgium there's two things that have surprised me on the anecdote side: Spain is the 10th country with more Facebook users and Belgium is the 7th oldest country in the social Network.
