This article at the New York Times discusses the severe gender skew in Wikipedia contributing authors. Less than 15% of contributors are female. The result is not only a skew in perspective for the articles that exist, but a severe skew in which articles get created in the first place. Articles on everyday things (rather than science and history topics etc.) are more likely to cover topics valued by men.
This is a problem that can be easily fixed by females who use Wikipedia (you!) contributing and adding to articles when they notice a need. Don’t know how to contribute to Wikipedia? Visit the Wikipedia contribution instructions!
