If we grade both genders in A,B,C,D, then D men and A women are reportedly ending up alone the most without a partner.
Minority guys (e.g. asian, east indian etc) have it really rough. Girls of their own race marry out with no problem but very few white girls would even look their way. I know 2 or 3 guys who'd make great husbands but just couldn't get any traction at all in the dating world.
