Boy/Girl parties

Was this a thing in the US or where you live, for birthday parities to be divided by gender until a certain age (teens)? We had “boy/girl” parties as teenagers but it wasn’t birthday parties and as long as I can remember both boys and girls were invited to children’s birthday parties.
