The site in numbers

Since we started this project in 2007, the amount of information in our database has grown hugely. As people have expressed an interest in seeing how it's developed, this page makes that information available. We only have three snapshots available from dates before 2010, so there's not a lot of old data available, but we've shown what we have. We'll update the numbers every three months in future.

(Note: the graphs may not display properly if you're using an out-of-date browser such as an old version of Internet Explorer. They definitely won't display if you have Javascript disabled.)

All figures are approximate, as they've been extracted automatically.
