Now that I got your attention … Prompted by a post from Jane Darnell, I thought to quickly run some gender-related stats on artists in Wikidata. Specifically, the number of articles on Wikipedias for artists with a specific property, by gender.
First, RKDartists (at the moment of writing, 21,859 male and 2,801 female artists on Wikidata):
As we can see, not a single Wikipedia reaches the unbiased line; all Wikipedia are biased towards male biographies. English, German, Dutch, and French Wikipedia come closest, however, that may be due to reaching saturation (as in, almost complete coverage of all RKDartists) rather than intrinsically unbiased views. Otherwise, Finnish Wikipedia seems to be closest to unbiased amongst the “mid-range” Wikipedias.
Doing the same for ULAN (33,057 men, 3,100 women) looks a little better:
I have uploaded both data sets here.
