For the first time in roughly 20 years, US computer science enrolment has dropped, signaling potential shifts in student preferences and market dynamics as AI technologies become mainstream.
- Enrolment down 4.6% on average across 1,019 US colleges
- National undergraduate enrolment in CS fell 8.1% in autumn 2025
- Multiple causes cited, including job market and data science growth
What happened
Research from Stanford's Hoover Institution economist Jacob Light reveals that undergraduate computer science enrolment in the US has decreased for the first time in over 20 years. Based on data from more than 50 million college course sections across 1,019 institutions since 1996, the average decline in CS class enrolment was approximately 4.6% year over year. National Student Clearinghouse data corroborates this trend, recording an 8.1% drop in undergraduate CS enrolment at four-year colleges during the autumn 2025 semester.
This decline follows a period of remarkable growth: computer science bachelor's degrees more than doubled from around 56,000 in 2014 to 122,000 in 2024. The 2025-26 academic year marks the first notable reversal of this long-term upward trajectory.
Why it matters
The timing of the enrolment drop coincides with the mainstream adoption of AI assistants capable of writing, debugging, and completing coding assignments, potentially impacting how students view the value and nature of computer science education. Additionally, the entry-level software job market has cooled, with major firms reducing tech staff and recalibrating workforce needs.
Analyst Jacob Light warns against assuming a single cause, noting several possible contributing factors: a weaker junior developer job market, declining confidence in the value of a CS degree, weaker math preparation among students, demographic shifts related to immigration, and increased interest in data science. This multifaceted set of influences reflects deeper changes in education and employment landscapes.
What to watch next
Despite the dip, computer science enrolment remains above 2022 levels, indicating this might be a temporary fluctuation rather than a permanent trend. The key question moving forward is whether this decline signals the start of a broader reconsideration of career paths and educational choices, especially as alternatives to traditional coding careers emerge.
Experts highlight that a STEM degree still offers a significant advantage in effectively utilizing AI tools, suggesting many graduates will continue to see value in formal CS education. Observers will be watching subsequent enrolments closely to discern if this drop proves an anomaly or the dawn of changing student preferences amid evolving technology and labor market realities.
