Google can determine user's gender and age when an user provide his name to a google account or to a google partner. Having an user name is easy to discover the gender using a service like Dots Name Validation (http://www.serviceobjects.com/products/demographics-more/name-validation).

Also many visitors uses a google account where their provide informations like gender and date of birth.

As you may see, the information is not 100% accurate. It's just a small estimative.

    "Not 100% accurate" is kind of soft actually. If they would show the number of google users you could sort of track it better. – ROmbout Sep 2 '15 at 14:17
