The old Facebook API provided the user sex/gender as part of the default user data. Apparently the new Graph API does not provide that information, even though the documentation says that it does.
I've heard people say that you need to request special permissions to get it and other pieces of data, but I have not been successful in getting it to work.
Does anyone have an example, using the Facebook Graph API, of how to get the user's gender and/or location (city/state/country/whatever)?
