I'll throw I.T. into the discussion here.  I still see far more men than women (I would venture to say that 70-80% of my technical contacts are male).  Pay is harder to gauge since it's not something we talk about, but my husband typically earns 30-50% more than I do for the same job description and my evals say the discrepancy is not because of performance.  At one point in my career this was true at the same Fortune 5 company, working in the same department, on the same projects.  I think my current employer does better at gender equality with regards to pay than most, but sad to say I do not see new female I.T. graduates at nearly the same rate as men, and frequently the jobs they end up taking are not in their field of interest.

at least it was at my school don't have the statistics for any others.

Pay might be influenced by field selection and schedule.  Nighthawk radiologists tend to be mostly male and they get paid a lot of money.
