I see this in the STEM field.
A couple years ago, I coached a high school robotics team. We had several girls and with one exception, they all filtered over to the marketing and administrative areas of the team. While they loved the team and frankly, the girls were the ones more responsible for some awards the team got, not the on field performance, they didn’t really care about the programming, electronics and mechanical aspects.
My son majors in aerospace engineering. Virtually every college brochure he got featured young students on the front cover. He attends a very small engineering university where he knows nearly all the students. He told me that they either use stock photo’s or bring in models for any student life promos.
For one, he doesn’t recognize and of the girls and secondly, there are less than a dozen females students on campus.
Man, I wish I had it here with me, but I went to a small, private university in the middle of Vermont, and they actually did use student pictures for the Engineering brochures. I was in a couple of the pics, but seeing as it was a military school, only about 3 percent of the students were female, yet they were in more than half the pics. Well, except for the one really big and beastly girl, she was only in one of more than a dozen.
When my auntie studie ME at UB Berkeley in the late thirties, there were two other women in the department
Those numbers haven’t changed over the years. EE and computer science have more women in them but most of those are Asian or Eastern European
Someone who was an engineering major once told me that the "PRG" (pretty girl ratio) drastically declines the higher up you go in that field.
