The Federal Bureau of Prisons has numbers on the sex of inmates. Of the 10,025 people in federal women’s prisons, 1,529 are men or 15.3%. Of the 143,714 people in federal men’s prisons, 744 are women or 0.5%. So-called transgender females are thus greater over represented in federal prisons relative to their share of women.

Do you have figures in the increase of pregnancies in these prisons?
Nope, but we looked for them. I agree that it is an obvious thing to look for.
