This isn’t a new issue, and it occurs at far more than just Duke. While more prominent at highly selective private colleges with open major enrollment, less selective colleges also show a similar type of pattern. For example, among all US colleges, the number of English bachelor degrees by year is below . Many non-STEM majors have been on a steady decline since the 2008 great financial crisis.
English Bachelor Degrees by Year in US
2003 to 2008: ~55k
2010: 53k
2012: 52k
2014: 46k
2016: 41k
2018: 38k
2020: 36k
2021: 35k (most recent available year)
As an example of a highly selective college with open major enrollment, I’ll use Stanford, as they have especially good reporting. The following majors at Stanford all have single digit enrollment (0-9 students) across a combined total of all years of students – all foreign languages and language studies; all single ethnic group studies; feminist/gender studies; religious studies; archeology; all school of earth, energy, and environmental science majors except earth systems; environmental engineering; etc. In contrast, CS enrollment grew from 141 students in 2008 to 865 students in 2023, making CS by far the most popular major of all time at Stanford. Nothing else is even in the ballpark. Number 2 economics has an enrollment of 227 – roughly 1/4 the major enrollment of CS.
There was a time when major enrollment was very different, where the most popular majors were non-STEM fields. For example, Stanford’s second most popular major of all time is history. History major enrollment peaked at over 600 during Vietnam and reached over 300 during fall of Soviet Union in the early 1990s, but today only has an enrollment of 47. After history, the 2nd most popular major was English. English major enrollment peaked at over 400 students during the 1960s and has been gradually dropping since then.
I think the change in major enrollment is both a reflection of which fields students perceive to be prioritized and what fields students perceive to have superior work opportunities. For example, the timing of the English decline across all US colleges noted above started during the great financial crisis, but the timing also coincided with Obama’s 2009 Education to Innovate program, with stated goals “to increase STEM literacy, enhance teaching quality, and expand educational and career opportunities for America’s youth.” The program included over $1 billon funding for STEM education. During this period I expect students had increasing pressure from parents, friends, teachers, and the general community to favor STEM fields over fields like English. This also contributes to why English major enrollment kept dropping after the great financial crisis was over and there was largely economic prosperity.
Employment prospects have also changed. At colleges like Stanford or Duke, ,CS majors often average triple the starting salary to the majors with low enrollment. For example, in Princeton’s senior survey, CS majors reported an average of $170k/year total comp compared to $40k/year for English majors and $30k/year for comparative literature. Students are aware of this difference in early career employment, and that difference influences major selection. There didn’t used to be this extreme a degree of variation in early career earnings between majors.
There is not a simple solution, as it depends on external forces beyond the college’s control. Stanford tried a CS+X program a few years ago. The idea was students could combine a major in a humanities field they were passionate about like English or foreign language with a more financially pragmatic CS major, integrating the 2 fields in to a joint major. It wasn’t popular with students, so Stanford ended the program. Most students just wanted to major in CS, without the +X. The small minority who wanted to study the other humanities field were fine with a double major, minor, or just taking electives; rather than requiring a special joint degree.
