Students can major in over 1,000 distinct fields at U.S. colleges and universities, spanning STEM, business, arts, social sciences, and health professions. These majors form the core of undergraduate education and determine the academic focus and career trajectory of a degree.
Colleges organize academic programs into broad categories based on subject matter and learning objectives. A major is the primary field of study a student commits to during their bachelor's degree. Majors typically require 30-45 credit hours of focused coursework beyond general education requirements. The choice of major influences job readiness, graduate school eligibility, and long-term earning potential.
The U.S. Department of Education's Integrated Postsecondary Education Data System (IPEDS) tracks degree conferrals across 500+ distinct fields. For example, in 2022, the most awarded majors were business administration (16% of all bachelor's degrees), computer science (8%), and psychology (7%). These numbers reflect both demand and institutional capacity.
A major defines the structure of a student's academic path. It includes required courses, electives, and often a capstone project or internship. Students declare a major early in their college careers, usually by the end of their sophomore year. Declaring too late may delay graduation due to missing prerequisites.
Each major follows a curriculum designed by faculty and approved by the institution's academic senate. For example, a biology major requires courses in genetics, cell biology, and biochemistry, along with lab work and research components. A marketing major includes classes in consumer behavior, digital advertising, and market research.
Some majors have multiple concentrations. A communications major might offer tracks in journalism, public relations, or digital media. These allow students to tailor their education to specific interests within a broader discipline.
Academic disciplines fall into several major categories. The following table outlines common types, their typical course load, and average entry-level salaries based on 2023 data from the National Association of Colleges and Employers (NACE).
| Category | Examples | Credit Hours | Avg Entry-Level Salary (2023) |
|---|---|---|---|
| STEM | Computer Science, Engineering, Mathematics | 45-60 | $72,000 |
| Business | Finance, Accounting, Marketing | 40-50 | $63,000 |
| Social Sciences | Psychology, Sociology, Political Science | 36-48 | $48,000 |
| Humanities | English, History, Philosophy | 30-42 | $42,000 |
| Health Professions | Nursing, Exercise Science, Public Health | 50-65 | $58,000 |
STEM and business majors consistently rank highest in starting pay. Computer science graduates earned $72,000 on average in 2023, according to NACE. Psychology majors averaged $48,000 - still above the national median for all bachelor's degrees, which was $56,000 in 2022 (U.S. Bureau of Labor Statistics).
Some majors blend disciplines. Environmental science combines biology, chemistry, and policy. A double major in economics and computer science is common among students aiming for roles in fintech or data analytics.
Many students assume that choosing a major determines their entire career. That's incorrect. A biology major can become a medical researcher, a science communicator, or a biotech policy analyst. The skills developed - critical thinking, data analysis, communication - transfer across fields.
Another misconception is that certain majors lead to guaranteed jobs. While engineering and nursing have high placement rates, humanities majors face more competition in entry-level roles. However, a 2021 study by the American Academy of Arts and Sciences found that liberal arts graduates had higher long-term earnings growth than expected, especially those who pursued advanced degrees.
Some confuse a major with a minor or concentration. A minor is a secondary field requiring 18-24 credits. A concentration is a subset of a major, such as cybersecurity within computer science. These don't replace the major but add depth.
Consider Alex, a high school graduate from Ohio. They wanted to work in tech but weren't sure whether to pursue computer science or information technology. After reviewing course catalogs, they discovered that computer science emphasizes algorithms, programming theory, and mathematical foundations. Information technology focuses on systems integration, network management, and software deployment.
Alex chose computer science because they enjoyed solving logic puzzles and building applications. Their university required four semesters of calculus, three programming languages, and a senior project. By junior year, they landed a summer internship at a local software firm through the campus career center.
After graduation, Alex secured a role as a junior developer at a SaaS company with a base salary of $78,000. This outcome reflects the direct alignment between major and career path common in technical fields.
For contrast, Jamie majored in English literature with a minor in digital storytelling. They didn't plan to enter publishing but took a course in web content strategy. After interning at a nonprofit's communications team, they transitioned into a content marketing role at a tech startup. Their major didn't dictate their job - it shaped their ability to write and think critically.
When deciding "what can you major in," consider both passion and practicality. Some majors, like computer science or finance, offer clear career pipelines. Others, like philosophy or art history, build transferable skills. The key is matching your strengths and goals to a program's structure and outcomes.
Students should consult official course catalogs and speak with academic advisors. Many schools provide career outcome reports for each major. For example, the University of Michigan publishes annual placement data showing that 89% of computer science graduates were employed or in grad school within six months of graduation.
"what can you major in" is not a list of choices but a map of possibilities. The right major aligns with your interests, supports your goals, and prepares you for a changing workforce.
