A big home for all facts and figures around social media - because I'm fed up of trawling around for them and I'm also sure that I'm not the only one who gets asked 'how many users does Facebook have?' every hour of every day.

1. Index This compares audience composition of the site or mobile app to each platform population. The higher the index number, the more concentrated the property is in a particular demographic. As an example, if a property indexes 100 for age 18-24, that means a given visitor to it is as likely to be 18-24 as any internet user chosen at random. An index of 200 means the visitor is twice as likely to be 18-24, 50 means half as likely, and so on. twitter.com - Quantcast Audience Profile twitter.com - Quantcast Audience Profile
