Your database here's pretty cool.
I have to say though, I wonder if the categories couldn't be simplified a little bit? Some of them seem to say the same thing. Or like, there's inconsistancy about what should come first...
Boys/Teen Female vs Teen Female/Boy
Female/Girl vs Girls/Female
I notice there's a subtle difference of plurality... is the way it works that it is in alphabetical order, with the exception of if it is plural, the plural word gets listed first? Of course that doesn't work with Teen Male/Teen Females... pretty confusing
