Facebook Demos: Not so young, not so male

New research released this week by Pingdom on social media usage in the US confirms what most of us already know from our everyday experience - Facebook isn't just for the young.

In fact, Pingdom's survey shows that 65% of Facebook users are 35 or older and that the average age of Facebook users is 40. The research looked at user demographics in the US for 24 of the most popular social networks.

For Facebook, Twitter, Linkedin and Pinterest -  the majority of users were all over 35. This colourful chart shows the breakdowns.
