Take a look at this article in The American Thinker which argues that the declining number of males in universities (down to 43%) is the result of feminism and women's studies programs. I suspect this is the right problem but the wrong diagnosis.
If you look at the number of men and women college graduates in various groups you find that the differences in some categories (i.e., European Americans, Asian Americans) are insignificant and in other groups are quite large. Historically much larger numbers of Hispanic and African American women have graduated from college than men from the same groups. The reasons for these imbalances are unclear and in any case beyond the scope of this post.
As colleges have attempted to make their student populations more representative of the national population, they have increased their enrollment of Hispanics and African Americans and have thereby, quite unintentionally, aggravated the female/male imbalance.
It is often the case that an attempt to solve one problem inadvertently creates another problem.
