Of course, the additional layer of context is that many of the Asians I was friends with spoke English as a second language. Maths and engineering and subjects like that are seen as being easier for people who don't like writing essays, and most of e.g. the Mainland Chinese people I knew at uni were either mathematicians or engineers. So, y'know, I don't know what the gender balance in the maths and engineering fields are like in Mainland China, whether there's even more of a bias towards men.

*nods* You're talking about the UK? Because yeah, I would expect it to be different in more of an expat situation. It's pretty similar in the US.
