That's a neat study, and I will definetly have to look at their other literature, but I think that 6 out of 21 not being close to parity isn't terrible. With three (probably four this year) having more women writers than men. I would like to know gender stats in regards to submissions too. If a magazine doesn't get as many submissions from women, for what ever reason, saying they aren't near parity would be rather unfair. There's always something to want to know about a study. Besides that though, I realize 'famous' poets are overwhelmingly male, it still seems to me that most poetry books being published these days are written by women. Especially in local and self-publishing spheres, with books stocked in local libraries, bookstores, and coffee shops. Like the study tla mentioned, I think there is a huge difference between 'professional authors' and all writers, which would be much harder to find data on.
