title: Get user age group info on Facebook without asking for birthday permission
body: <p>Is there a way to know the age group an user falls under (like the break down they show on the demographics section on the application insight) without asking for their birthday permission?</p>
  
  <p>I don't need to know their birthday details - I just need to know if they fall into 18-24 bucket, 25-34 bucket, so on and so forth.  It appears that many of the games out there have access to this information and use it in fine tuning their ad spend and ad targeting.</p>
  
  <p>Anyone has any idea if this is possible?</p>
  
  <p>Thanks!</p>
