Between 2015 and 2019, according to the National College Clearinghouse, the number of men on campuses declined by 691,643, almost double the smaller fall among women, 348,955. In percentage terms, the male decline of 8.34 % was far more than double that among women, 3.18%.
Women have for decades outnumbered men in America's colleges. In 2015, there were 32% more women than men, but now the differential is nearly 40%. For every five men, there are seven women. The fundamental question is why —not only do far more women attend college than men, but why is the differential growing noticeably in the past few years?
While several factors may be at work, I think at least part of the reason is a perception among males that colleges dislike them —or at least do not like them as much as women. There are several forms of discrimination against males that are increasingly turning men off to the collegiate experience. They don't like being second class citizens.
