Why would representation be an issue? You make it sound like there are no women at all in male-dominated fields, but the gender ratio lies around the 30% mark. So although they are not the majority, nobody will bat an eye that a mathematician or a physicist is a woman. If by representation you mean support, women have way more support than men in terms of funding and ease to get fixed positions.
And frankly I do not think young people are making career decisions based on representation. That's more of an academic's way to look at life.
