Remember? At this time, of the sum of all the 195085 notable people with an alma mater, 158649 are men and 29059 are women for 7377 no gender is known.
They include all the boys and girls of *your* university. Take the University of Virginia for instance. When I first looked at it, there were only 142 alumni. The category knew about at least 815 more of them. They are being added as well, software permitting.
This query has all the UoV alumni. These are all the men and these are all the women.. Maybe this is a good time to write Wikipedia articles, identify articles to Wikidata about the female UoV alumni.
