How to Become an Epidemiologist: Degree & Salary (2026)
Key takeaway: Epidemiologists study who gets sick, why, and what changes that -- through study design, surveillance, and analysis. There is no license and no required certification, but the job market has a hard practical gate: most positions require a master's degree with a substantial epidemiology and biostatistics core, usually an MPH. Epidemiologists earned a national median annual wage of $87,220 (Bureau of Labor Statistics, May 2025 OEWS). Employment was 12,300 in 2024, with 16.2 percent projected growth through 2034 and about 800 openings per year (BLS Employment Projections, 2024-2034). It is a small occupation growing quickly, which means competition.
Epidemiology is the method underneath public and global health. An epidemiologist designs a study, defines a case, chooses a comparison group, controls for the things that would otherwise explain the result, and then says what the data support and what it does not. The settings vary: state and local health departments, federal agencies, hospitals and health systems, universities, research institutes, pharmaceutical and device companies, and international organizations.
No state licenses epidemiologists. Certification exists in adjacent specialties, but there is no single credential that authorizes the work. What functions as the gate is the transcript. Postings ask for graduate methods coursework, and hiring managers read the course list.
Step-by-step: how to become an epidemiologist
-
Build the quantitative base as an undergraduate. Take statistics, calculus if your program offers it, and as much biology or human health as the major allows. A bachelor’s in global health, public health, biology, statistics, or a social science all work. What matters is that you arrive at graduate school able to handle regression rather than meeting it for the first time.
-
Get data experience before you apply. A research assistant position, a health department internship, or a role that involves cleaning and analyzing real records is the most useful thing you can do between the bachelor’s and the master’s. It also gives your statement of purpose something concrete to say.
-
Earn the master’s degree. This is the practical requirement for most positions. The common route is an MPH with an epidemiology or global health concentration, accredited by the Council on Education for Public Health (CEPH). An MS in epidemiology is the more research-weighted alternative and is often the better preparation for a doctorate. Verify institutional accreditation through the U.S. Department of Education database, then confirm the degree’s CEPH status separately.
-
Take more methods than the minimum. Programs let you choose electives. Advanced epidemiologic methods, a second and third biostatistics course, survey and sampling methods, and a course in statistical programming do more for your employability than an additional topical elective. Learn one package well: R, SAS, or Stata.
-
Use the applied practice experience as a hiring credential. CEPH-accredited programs require an applied practice experience producing deliverables for a real organization. Choose a host that will give you a dataset and a question rather than a communications assignment. A finished analysis you can describe in an interview is worth more than the course title next to it.
-
Apply to entry roles under several names. Openings appear as epidemiologist, surveillance analyst, public health analyst, research analyst, and monitoring and evaluation officer. State and local health departments are the largest entry point. Federal and international postings are more competitive and often expect prior agency experience.
-
Decide whether you need a doctorate. A PhD or DrPH is generally required to lead independent research or to hold faculty positions. It is not required for the practice-side epidemiology that health departments and hospitals hire for. Medical scientists, except epidemiologists, an occupation dominated by doctoral degree holders, earned a median annual wage of $103,410 (Bureau of Labor Statistics, May 2025 OEWS).
What degree do you need to be an epidemiologist?
There is no legal requirement, but there is a practical one:
- A bachelor’s degree alone rarely reaches the epidemiologist title. It does reach data and research assistant roles, community health work, and health education. Health education specialists earned a median annual wage of $64,070 and community health workers $51,850 (Bureau of Labor Statistics, May 2025 OEWS).
- A master’s degree is the working requirement for most postings. An MPH in epidemiology or global health is the common professional route; an MS in epidemiology is the research-weighted route. See the online master’s in global health page for how the two differ.
- A doctorate is for independent research and faculty positions, not for entry.
Consider whether the destination is domestic or international. For U.S. health department work, a public health degree title is the most directly recognized. A global health concentration is the better fit if cross-border disease, comparative systems, or work with international organizations is the target. See Is an Online Global Health Degree Worth It? for how to weigh that choice.
How much do epidemiologists make?
Epidemiologists earn a national median annual wage of $87,220 (Bureau of Labor Statistics, May 2025 OEWS). Half earn more and half earn less. The spread is substantial: the 10th percentile was $61,270 and the 90th percentile was $138,800 (Bureau of Labor Statistics, May 2025 OEWS). Employment stood at 12,300 in 2024, projected to grow 16.2 percent through 2034, with about 800 openings per year (BLS Employment Projections, 2024-2034).

| Percentile | Annual wage |
|---|---|
| 10th percentile | $61,270 |
| 25th percentile | $71,090 |
| Median | $87,220 |
| 75th percentile | $112,640 |
| 90th percentile | $138,800 |
Read the growth and the openings together. A 16.2 percent projected increase is well above average, and 800 openings per year is a small number in absolute terms. Employer type explains much of the wage spread: research institutions, pharmaceutical and device companies, and hospital systems generally pay above state and local health departments, and geography moves the number further.
Related occupations for people who take the methods training somewhere else: medical scientists, except epidemiologists, earned a median annual wage of $103,410, with 8.7 percent projected growth and 9,600 openings per year. Medical and health services managers earned $123,860, with 23.2 percent projected growth and 62,100 openings per year. Social and community service managers, a common nongovernmental title, earned $80,390, with 6.4 percent projected growth and 18,600 openings per year (Bureau of Labor Statistics, May 2025 OEWS; BLS Employment Projections, 2024-2034).
How long does it take to become an epidemiologist?
| Phase | Typical duration |
|---|---|
| Bachelor’s degree with quantitative coursework | About 4 years from scratch; shorter with transfer credit (approximately 120 semester hours) |
| Data or research experience before graduate school | Optional but common; often 1 to 2 years |
| Master’s degree (MPH or MS) | Varies by school, degree type, and enrollment intensity – confirm credits and the practicum timeline |
| Applied practice experience | Completed inside the master’s; spans weeks to a full term depending on the program |
| Doctorate, if pursued | Additional years; required for independent research and faculty roles, not for entry |
These are ranges rather than guarantees. Catalogs set credit totals and practicum rules; employers set their own hiring bars.
Frequently asked questions
What degree do you need to be an epidemiologist?
Most positions require a master’s degree with a substantial epidemiology and biostatistics core, usually an MPH or an MS in epidemiology. A bachelor’s alone reaches analyst and research assistant roles rather than the epidemiologist title. A doctorate is required for independent research and faculty positions.
Do you need a license to be an epidemiologist?
No. There is no state license for epidemiologists and no single required certification. Institutional accreditation matters when you choose a degree, and accreditation by the Council on Education for Public Health is the standard check for a professional public health degree. Verify schools through the U.S. Department of Education database.
How long does it take to become an epidemiologist?
Typically about four years for the bachelor’s, then a master’s whose length varies by school and enrollment intensity. Many people work in a data or research role in between, which strengthens both the application and the first job search.
How much do epidemiologists make?
Epidemiologists earn a national median annual wage of $87,220, with the 10th percentile at $61,270 and the 90th percentile at $138,800 (Bureau of Labor Statistics, May 2025 OEWS). Employer type and geography drive much of that spread.
Is epidemiology a good career choice right now?
Projected employment growth is 16.2 percent from 2024 to 2034, well above the average across occupations, but the occupation is small and produces only about 800 openings per year (BLS Employment Projections, 2024-2034). Candidates with strong methods coursework, statistical programming skills, and a real applied practice experience compete best.
Can I become an epidemiologist with an online degree?
Yes, if the program is institutionally accredited and, at the graduate level, CEPH-accredited. What employers examine is the methods sequence and the applied practice experience, not the delivery format. Confirm before enrolling how the program arranges practicum placement for online students – see how online global health degrees work.
