Hello,
I'm doing a project at the moment, and writing a paper, that proposes a Wikipedia Gender Index - like the United Nations Gender Inequality Index. Essentially it will show the proportion of represented (existing article in the Wiki, not editors) Genders over time (both historical time, and as Wikipedia evolves), by language edition, by occupation, and by ethnic group.
I want to be sensitive to the many categories of non-male and non-female genders that exist in Wikipedia. Another balance is make the Index compatible with the other indexes so we can compare. Some of those other indexes are M/F. So the question is: it could be M/F/Other, M/F+Other (Male/Non-male), M/F/All/the/other/categories. I don't say that any of these are correct. I'm ask if you, or you know any researchers that has studied these decisions and can advise.
