I understand (second-hand, since I don't surf much) that there is some concern out there in InterNet Land that the Hugo ballot features only four women nominees this year (last year there was only one). As it happens, gender distribution of SF writers is something I keep track of. Here are the figures from the 2007 SFWA Directory:
Male names: 58%
Female Names: 35%
Other: 7% (These people are unknown to me personally and are using initials, have unisex names like "Pat" or "Terry," or have non-English names which I don't know the usual gender for).
Now, the awards record. From 1977-2007, there were:
Female Hugo winners: 35
Male Hugo winners: 93
Female Nebula winners: 57
Male Nebula winners: 70
So women are under-represented for Hugos and over-represented for Nebulas. Why? I have absolutely no idea. Do any of you?
