my2cents re figures on percentages (... in a gender binary paradigm), well...

I'd suggest to take into account User:Pundit's thoughtful considerations,

author of: Jemielniak, Dariusz (2014), Common knowledge? An ethnography
of Wikipedia, Stanford University Press, pp. 14-15

Dariusz Jemielniak writes:
"According to Wikipedia Editors Study, published in 2011, 91 percent of all Wikipedia editors are male ([reference to a study of 2011] This figure may not be accurate, since it is based on a voluntary online survey advertised to 31,699 registered users and resulting on 5,073 complete and valid responses [...] it is possible that male editors are more likely to respond than female editors. Similarly, a study of self-declarations of gender showing only 16 percent are female editors (Lam et al. 2011) may be distorted, since more females may choose not to reveal their gender in a community perceived as male dominated."

additionally, asserting status and flaunting seniority (also described by Jemielniak at the end of the paragraph previous to the one quoted above) is generally perceived to be a commonly employed trick to resist any changes;

and, last but not least, one might argue that the group perceived as "in power" might feel to find strongly unbalanced outcomes most rewarding, and hence might tend to publish them as widely as possible and not least quote from them persistently, too...

any rebuttals from stats experts here?

best,
