I think I am at a pretty even 50/50 gender split for my pawn hires, only I have to go much more out of my way to find male pawns since there are so many females. I always pick pawns based on their looking unique or original in some way. I actively avoid hiring any dolled up girls or ones designed to look like little kids and any that have what I deem a "stupid" name. If your pawn is elderly, fat, skinny, ugly, black or any other non-caucasian, there's like a 99.9% chance I want it on my team.
