adCenter Labs tools - demographics

Microsoft have made a very interesting bunch of tools available. In some ways I’ve no idea how get the stats they are using and if they can be trusted but on the other hand it makes for some interesting reading anyway.

For example just taking a look at the demographics prediction tool. We can see that the a4uforum shows a slight male bias.

Tradedoubler shows some more balanced stats

But the stats for dgmpro are very strange!
