I find not too many woman are interested in magic. They simply don't pursue it. Magic starts typically when you are young and most girls or young woman don't have hobbyish hobbies. Much of the woman I know danced, sang, played instruments, did gymnastics, all stereotypical things woman did at younger ages. Its not particularily negative, its just natural that they pursue what they see other woman do, acting talents such as I have listed.
I would like to see more woman magicians, variety and spread interest is a good thing. For me though I don't really care deep into having variety into things, if they don't do it thats ok, if you're a woman magician I am not setting you higher as you are unique in that such way.
Just wanted to respond as these sort of variety question are always tossed about near me.
P.S. If you're offended (as some have been) that I don't set others higher for them being one of few in a popular area then cut short that comment because I don't care to answer to that anymore.
