Overqualified

On the BBC website there was this article about increasing dissatisfaction among university students in the UK, as measured by their response to a survey question about whether their studies provided “good value for money”, and questions about their happiness and wellbeing. I was struck by this sentence:

Young women and gay students at university are particularly likely to feel unhappy.

Why “young women” and not simply “women”? I’m willing to bet that they are not basing this on a distinction in reported happiness between younger and older female students. Those who are gay are referred to simply as “students”. Most students are, in a general sense, young, but why is this emphasised for the women? Why are the women not referred to as students? I feel like there is some invidious stereotyping going on here, but I can’t quite put my finger on what is irritating me.
