career profession segregation.
Great advice from Delilah! Well, if you are doing this topic, you should think about the best search terms to use.
I would search the school library database for articles about these terms: glass ceiling, represented, gender
Those terms above will help you write about women being underreperesented in some professions.
You can also search for the terms: professional, segregation, number, minorities
This is a tough one! Can you be clearer about the topic you need to write about? Like Delilah, I am not sure I understand you correctly. :-)
