Public Health major
Public Health: courses, careers, and where to study
Public Health studies how to prevent disease and protect population health, suiting students who want to improve community well-being through data, policy, and programs rather than treating patients.
A Public Health major covers epidemiology, biostatistics, environmental health, health policy and management, and the social and behavioral determinants of health. Coursework pairs foundational sciences (biology, anatomy, microbiology) with population-level methods, study design, survey research, data analysis, program planning, and evaluation. Most undergraduate programs award a BS or BA in Public Health and include a practicum or internship with a health department, hospital, nonprofit, or community organization.
Graduates work in disease surveillance, health education, program coordination, community outreach, and policy analysis across local and state health departments, hospitals, nonprofits, and global-health organizations. Many roles, including epidemiology and other analytical positions, expect a Master of Public Health (MPH); the bachelor's is a common stepping stone into that graduate path.
Public Health is also a growing field. The U.S. Bureau of Labor Statistics projects that employment of epidemiologists will grow about 16.2% from 2024 to 2034, faster than the average for all occupations.

Before you commit to a Public Health major
CampusPin does not rank programs. Use these prompts to pressure-test whether a specific Public Health program fits your goals, they are decision questions, not claims about any school.
Ask the Public Health department
- Which concentrations or specializations are offered, and which faculty lead them?
- What does the typical course sequence look like, and how much is required vs. elective?
- What labs, studios, clinical placements, or research opportunities are available to undergraduates?
- Is there a capstone, thesis, internship, or co-op requirement?
Ask current students & check the curriculum
- How heavy is the workload, and how accessible is the faculty?
- What internships or co-ops did you do, and where do recent graduates end up?
- Does the required curriculum actually match the careers listed above?
- How easy is it to add a minor, double major, or switch tracks later?
