I'm from Romania. The general balance is pretty far from 50/50, and there are some not-so-nice jokes about women in CS (e.g. "mamma had 2 girls; one was smart & beautiful, the other one went on to study computer science"). Still, from what I saw (I work in a US company) - I suspect it's far better than US, and maybe even western europe[1]. There's no expectation that if you're a girl you must suck at math (or science/engineering in general), and in general I'd say programmers want/ like to have girls around. But it's still a fairly masculine environment, with some fair level of "bro" culture, so it must be somewhat tougher for a girl. It's double-edged though... the US "positive discrimination" culture is making inroads here, so on some aspects it's easier to be a girl in tech (I suspect it's actually easier to get a job compared to an equally-qualified guy).

The thing is - positive discrimination doesn't solve the problem, because it comes from school. You need to encourage girls to take science classes - it has to be expected of them that they do so (rather than go towards, e.g., humanities). That, I don't think is actively happening in the US or even some parts of western europe.... by the time you're dealing with graduates, it's already too late to fix the gender-imbalance problem.

[1] My little daughter's godfathers are German (she grew up in Romania, but he didn't). She told me that among german women, it's a thing of pride to be bad at math. And that her daughter was praised in school that "you're pretty good, for a girl". With that sort of attitudes during childhood... it's bound to be hard to get gender balance later (that "praise" would be perceived as insult here)
