Coincidentally, I have the 2011 survey data open in my stats package. I can report that there is not a statistically significant difference in reported level of education between those who report being male or female but the average age reported by women is 33.4 and by men, 31.9, and that difference is statistically significant. 

Looking through the other variables, the few others that I checked (e.g., children) were not significantly different statistically, with the exception of self-reported performance: men averaged 6.25 (on a 1-10 scale, not at all good to extremely good) while women averaged 6.0, and the difference is statistically significant. You may make of that what you will :-)

If you are curious about any of the other items on the survey, I’d be happy to check them.

Subject: Re: [Wiki-research-l] Gender bias in GitHub (but not entirely what you expect)

So I can easily believe the average women on GitHub is of a higher standard of ability than the average male. I suspect the same holds true about Wikipedians. Does anyone actually have the 2011 editor survey data to compare male vs female on other questions like age, level of education, etc. It would be interesting to know how the male and female Wikipedians of 2011 are statistically different in other ways.
