I don't know and I don't care. How the current ration of male/female judges has anything to do with the heavy discrimination against men that Bidet's administration exhibits?
Anyway, up until fairly recently, men outnumbered women in law schools, so of course there would be more men in federal benches than women: they have a higher pool to pick the most qualified candidate from.
Except that from 2021 and on, Biden decided that a veeeery important qualification for a federal judge, is to not have a dick.
EDIT:
I checked. Women lawyers (per 2020 report) are 37.4% I guess that 10 years ago they were probably about 1/3.
State judges in 2021 are about 1/3 women. Federal judges are about 1/3 women. So... about 1/3 of women are lawyers for at least a few years, 1/3 are judges in lower courts and that was, up to March 2021, correctly represented in the amount of seats they held in the Federal courts.
And then, came Bidet and started heavily discriminating against men. In a fair system, about 35%-40% of new hires would be women as that is their representation in the lower courts.
