In my earlier post, I mentioned that at highly selective colleges the overall average gender balance was 52% female / 48% male – both among applicants and entering students. If you look at all 4-year colleges, rather than just selective ones, then the numbers are similar – approximately 52% female / 48% male, as summarized below.
High School Graduates – 49.8% female / 50.2% male
Recent Grad: 2-Year College Enrollees – 50.9% female / 49.1% male
Recent Grad: 4-Year College Enrollees – 51.6% female / 48.4% male
I expect you are referring to specific colleges on your list that have larger discrepancies, rather than the overall average. Many colleges are far off from this average – some with gender skewed towards women and some with gender skewed towards men. Colleges that are not highly selective have limited options to try to balance genders, so the college gender balance tends to follow the application gender balance.
In general, colleges with a large portion of students enrolled in engineering/CS are skewed in towards of men, unless they are selective enough to balance genders during admission. Military and maritime schools also have a severe skew. Examples include:
Florida Polytech – 87% male
Virginia Military – 87% male
Mass Maritime – 86% male
LACs without much engineering/CS, religious colleges, and colleges with high URM enrollment tend to be skewed towards women, unless they are selective enough to balance genders. Nursing schools often have a severe skew towards women. Examples include:
St. Elizabeth Nursing – 95% women
Hebrew Theological – 80% women
Sarah Lawrence – 73% women
Howard – 69% women
