The most recent federal data (NCES, 2021-22, the latest year fully published) puts business in first place by a wide margin, followed by health professions, social sciences and history, biological and biomedical sciences, psychology, and engineering. That ranking looks stable from a distance, but the reasons behind each entry are genuinely different -- and one major on this list, computer science, just posted its first national enrollment decline in nearly 20 years, which is a useful reminder that "popular" is a moving target, not a fixed label.

The current top six, by degrees actually conferred

  • Business: 375,418 bachelor's degrees, about 19% of all bachelor's degrees awarded that year -- more than double the next field.
  • Health professions and related programs: 263,765 degrees (13%), a category dominated by nursing.
  • Social sciences and history: 151,109 degrees (7%).
  • Biological and biomedical sciences: 131,462 degrees (7%).
  • Psychology: 129,609 degrees (6%).
  • Engineering: 123,017 degrees (6%).

Computer and information sciences sits just below that group at 108,503 degrees -- worth flagging up front, since its trajectory has flipped hard in the years since this data was collected, covered below.

Why business has been on top since 1975 almost without interruption

Business has held the number one spot in nearly every year since 1975, and the reasons are more structural than trendy. The National Association of Colleges and Employers' Winter 2026 Job Outlook survey found finance and mechanical engineering tied for the most in-demand major among employers at 61.3%, with computer science at 60% and accounting and business administration/management at 58.7% -- meaning employer demand for business-adjacent degrees is broad and consistent, not concentrated in one narrow track. Georgetown's Center on Education and the Workforce, in a 2026 analysis of more than 5,500 individual business programs, found the degree delivers genuinely solid returns -- bachelor's-level business graduates earn a median $43,200 annually after debt payments, with most programs generating earnings roughly 10 times graduates' debt payments two years out -- while being explicit that business's returns are "not as high as returns associated with health, engineering, and computer and information sciences programs." In other words, business is popular less because it's the highest-paying option and more because it's a reliably safe, broadly employable one that doesn't require committing to a single narrow career the way, say, nursing or engineering does.

Why health professions have "never been more popular"

Health professions' growth is demographic, not just a matter of preference. The Bureau of Labor Statistics projects healthcare and social assistance to be the fastest-growing sector in the U.S. economy through 2034, adding roughly 2 million jobs -- the largest gain of any sector -- driven directly by an aging population (Americans 65+ are projected to grow from 59.7 million in 2024 to 72.5 million by 2034) and rising rates of chronic and behavioral health conditions. That national demand shows up directly in enrollment: nursing schools alone saw BSN enrollment rise 7.6% in the 2025-26 cycle -- a third consecutive year of growth -- while simultaneously turning away a record 93,176 qualified applicants, meaning the constraint on this major right now is program capacity, not student interest. See our piece on which majors are best positioned for the AI era for why nursing specifically sits in a structurally protected position other majors don't.

Why psychology stays near the top despite comparatively modest pay

Psychology's popularity is the clearest case of a major driven by genuine interest rather than pure earnings math -- bachelor's-level psychology graduates report a median salary closer to $55,000, well below business, health, or engineering. Bachelor's degrees in psychology grew 72% between the 2000-01 and 2020-21 academic years, a growth rate steeper than most other large majors over the same stretch. Psychology's own field describes itself as a "hub science" that connects to counseling, HR, UX research, marketing, education, and public health alike, which gives it real flexibility despite a narrower direct-application job market than something like nursing or accounting. Rising public attention to mental health specifically -- amplified further since the pandemic -- is also a widely cited factor in sustained interest in the major, alongside straightforward personal curiosity about human behavior.

Computer science: the sharpest live example of how fast "popular" can reverse

Computer science is worth treating separately, because its recent history undercuts the idea that a major's popularity is stable once established. It was one of the fastest-growing majors in the country for roughly two decades, tracking the tech industry's hiring boom and high starting salaries -- NACE's Class of 2026 data still puts computer science starting salaries at $81,535, the highest of any major category. But undergraduate CS enrollment fell 8.1% nationally in fall 2025, and a separate Stanford analysis found a 4.6% decline in the 2025-26 academic year -- the field's first national enrollment drop in almost 20 years, driven by AI's disproportionate effect on entry-level developer hiring. See our full breakdown of what's actually happening in computer science for the underlying job-market data. The relevant lesson here isn't "avoid CS" -- it's that a major's popularity tends to track a fairly recent read on the job market, which means it can move in either direction faster than most students expect when they're choosing a major as a high school senior.

What actually ties the popular majors together

Pulled apart, these majors are popular for different specific reasons -- but the underlying pattern across nearly all of them is the same: each one maps onto a legible, widely understood career path, a real and currently strong labor-market signal, or both. Business and engineering lean hardest on the labor-market signal. Health professions combines both a strong signal (BLS's own projections) and demographic necessity that isn't going away. Psychology leans more on flexibility and genuine interest, with a real but softer connection to career outcomes. And computer science shows what happens when the signal itself shifts quickly -- the major's popularity was never really about the subject in the abstract, it was about what the job market was visibly rewarding at the time students were choosing.

What this means for you

  • Don't treat "most popular" as a synonym for "best paying" or "best ROI." Business is the most popular major by a wide margin but delivers weaker average returns than health, engineering, or computer science, per Georgetown's own analysis -- popularity and payoff aren't the same ranking.
  • A major's current popularity reflects a recent read on the job market, which can shift within a few years. Computer science's reversal happened fast enough to affect current high schoolers' choices in real time -- treat any "hot major" claim as a snapshot, not a guarantee, when you're the one committing four years and real tuition to it.
  • If you're drawn to a major mainly for its flexibility rather than a specific career target (psychology, business, communication), that's a legitimate reason to choose it -- just go in aware that flexibility usually trades off against a narrower, guaranteed direct-application job market compared to something like nursing or accounting.
  • If genuine interest and a strong, structurally durable job-market signal point to the same major (nursing is the clearest current example), that combination is worth weighing seriously -- not every popular major has both working in its favor at once.
