Area, ethnic, cultural, gender, and group studies (I'm assuming "Grievance Studies" falls under this category), at least in the US, have been in steady decline since 2008, and even at their peak only accounted for 0.5% of majors (now just 0.3%). Even if you want to add in humanities in general that has gone from 3% to just above 2%

The idea that college campuses are ever more filled with people studying "useless" majors is a fiction. The largest areas of major concentration are business, biology, health professions, and engineering and all of these have been more or less growing for years.

There is this pervasive myth that most students in undergrad are having trouble transitioning to industry because they wasted their time studying their non-practical passion, but the data[0] clearly shows that the trends for the last decade have been increasing focus on career oriented practical majors.
