What are some ways to display 3 dimensional data in a table?

I have some data that has 2 dimensions that I currently display the values of in a table. The dimensions are Gender & Age. For example "there are 12 thirty year old Males".

Now I need to add a 3rd dimension to this data visualization - Religion. Ideally it would help the user:

  1. See what intersections are represented (eg. there are 8 thirty year old, Christian Males)
  2. See what intersections are not represented (eg there are no twenty five year old Buddhist Females)

What are some ways to present this data in a meaningful way that helps the user achieve the two objectives outlined above?
