My understanding, from a long-ago report which I cannot find, was that the children of lesbian couples do better than average: higher college admission rates, lower prison rates. It was thought that the relative difficulty of having children as a lesbian couple (including, in the case of adoption, which is understandably more prevalent among such couples, state approval) means that they're better prepared for child-rearing.

> Are men raised by lesbians entering the prison system at the same rate as men raised by single mothers?

Now that is a question that researchers won't ask nor tell.

Why do you feel that's the case?

Not enough data yet, as that's a recent thing.
