There have been a lot of questions about how computer science relates to other fields in terms of the percentage of women vs. men. As is to be expected when a bunch of scientists talk about these types of topics, we want the data. Happily, the Association for Women in Science collects statistics about all of these questions - both for within the sciences comparisons and for comparisons with other disciplines. I used this data to create the charts shown here. Both are based on the data for bachelors degrees awarded in 2004-2005 (in the US, I think). Also, note that the percentage of female graduates overall is much higher than the percentage of men. So, to answer some of the questions by commenters:
- Yes, Physics and Math/Stat are doing much better than CS at graduating a higher percentage of women.
- Yes, there are a few disciplines that do just as poorly in graduating men.
- Yes, if we define computer science more broadly, our percentages of women do go up, but no, we still don't reach parity (see chart below).
The next chart decomposes the bars labelled "Computer and Information Sciences and Support Services" above. Note that despite that we almost reach 40% women in some of the subfields, the overall percentage is still only just over 20%, and the "Computer Science" category has about 17%.
