What is the problem you're trying to solve?
Once we have the data, then we can put together a distribution of women's contributions to Wikipedia based on their geographic location. This would give us a better idea of where in the world women edit the least number of articles.
What is your solution?
Whenever someone is editing an article or creating one (their first article) just simply ask them two questions: 1. Where do they live; 2. What is their gender. This would enable Wikipedia to compile information on users that edit Wikipedia articles. Once we have a clear understanding of the distribution of female contributors around the world, then if feasible, we can try to address the problem in countries with lower rankings.
