What you earn and what it costs to get there.
Median
$87,220
Bottom tenth
$61,270
Top tenth
$138,800
The national median is $87,220 a year, the bottom tenth start near $61,270 and the top tenth reach about $138,800. The split inside that range is mostly about who employs you: city and county health departments sit low, universities and hospitals sit in the middle, and drug and device companies sit at the top.
About $61,270 to $70,000
Analyst or epidemiologist at a state or local health department
Public health salaries are set by government pay scales, so there is little room to negotiate, but the benefits and pension are real and the work starts on day one rather than after years of apprenticeship.
About $138,800
Top tenth: industry and senior federal roles
Drug companies hire epidemiologists to study how medicines behave once real people take them, and they pay well above health department rates. Senior federal scientists and university faculty with grant funding also reach this end.
Tuition, fees, exams and kit. Not rent, food or travel
The low end is a cheap four year degree, a community college start then a transfer to an in state public university, followed by a two year master of public health at in state public prices. The high end is four full years at the public university price and a more expensive public master's, and private schools run well above even that. A doctorate, if you go that far, is usually funded with a tuition waiver and a stipend for research or teaching, so it does not add to this figure. Health departments, public universities and most hospitals qualify for Public Service Loan Forgiveness, which cancels the rest of your federal loans after ten years of payments.
File the FAFSA (Free Application for Federal Student Aid) every year, for the master's as well as the bachelor's. Health departments, public universities and most hospitals are qualifying employers for the Public Service Loan Forgiveness program, which cancels the rest of your federal loans after ten years of payments. That matters more in public health than in almost any other science career.
State and local health departments
Surveillance, outbreak response, immunization and chronic disease programs. The classic job and the one with the most openings.
Federal agencies
The CDC (Centers for Disease Control and Prevention) and other agencies, paid on the government's set pay ladder.
Hospitals and health systems
Infection prevention, quality data, and tracking what is spreading inside the building.
Universities
Research funded by grants. More freedom, less security, and you spend a lot of time writing funding applications.
Drug and device companies
Safety monitoring and real world studies. The best paid branch and the least publicly visible.
The exact path from high school to qualified.
A science bachelor's then a public health master's. Six years, and you are paid from the first job.
High school diploma
Grade 12
Biology, statistics and as much math as your school offers. A computer class is worth more here than in most health careers.
Bachelor's degree
4 years
Biology, statistics, public health, mathematics or nursing all work. Get research experience with a professor, even unpaid, because it is what admissions committees look for.
Master of public health in epidemiology
2 years
Two years covering study design, biostatistics and data analysis, plus a supervised practice placement. Choose a school accredited by the Council on Education for Public Health.
First job
Hired on
Health department, hospital or research group. You will spend it cleaning and analyzing data, which is the real craft.
Optional doctorate or fellowship
2 to 5 years
A doctorate for research leadership, or a federal field fellowship for hands-on outbreak work.
Statistics
The single most useful class. Epidemiology is applied statistics about people.
Biology
You need to understand how diseases actually move.
Computer science
Writing code to handle a messy dataset is a daily skill in this job.
English
Your findings only count if a mayor or a doctor can read them.
No state licenses epidemiologists and there is no exam you must pass to use the title. What employers check instead is where you studied: the Council on Education for Public Health accredits schools and programs of public health, and government hiring rules frequently require an accredited degree. There is a voluntary credential, Certified in Public Health, from the National Board of Public Health Examiners, which some employers reward and none require.
Accredited schools of public health
Dozens of them across the country, at public and private universities. The accreditation is what makes a degree count for government jobs.
The University of North Carolina Gillings School of Global Public Health
In Chapel Hill, North Carolina. Runs an applied epidemiology master's, a clinical research master's and the largest epidemiology doctoral program in the country.
Your own state university
In-state tuition at a public school of public health is the cheapest sensible route, and local health departments hire from it.
Online master's programs
Several accredited schools run them part time, which lets you work while you study.
Things you don't need, but that help.
Infectious disease
Outbreaks, vaccines and surveillance. The part of the job people picture.
Chronic disease
Cancer, diabetes and heart disease over decades. Slower, bigger, and where most of the deaths are.
Drug safety
Watching what happens once a medicine is on the market. Best paid branch of the field.
Environmental and occupational
What a workplace or a neighborhood is doing to the people in it.
Injury and violence
Crashes, overdoses and firearms treated as a public health problem rather than a crime story.
Coding
The statistical languages R and Python, plus SQL (the language used to pull data out of a database). This is the skill that gets you hired.
Mapping software
Geographic information systems (GIS) turn a spreadsheet of cases into the map that makes people act.
Spanish or another second language
Interviews during an outbreak happen in whatever language the community speaks.
A volunteer stint at a health department
Immunization clinics and data entry are dull and they teach you how public health actually runs.
The Epidemic Intelligence Service is the applied epidemiology training program run by the Centers for Disease Control and Prevention. It is two years long, takes people who already hold a doctorate or an advanced health degree, and puts them on real outbreaks with a mentor. It started in 1951 and has trained more than 4,100 officers, who have worked on smallpox, HIV (the virus that causes AIDS), Ebola and the coronavirus pandemic. It is competitive, and it is the closest thing this field has to a famous apprenticeship.
Day to day, pros and cons, where you'd work.
Open the surveillance dashboard and check whether anything moved overnight. Clean a messy dataset that arrived from four hospitals in four different formats. Run the analysis, then spend longer than you expected working out whether the pattern is real or an artifact of how the data was collected. Write a short brief for people who do not read statistics. A weekly meeting with nurses and program staff. When there is an outbreak, all of that stops and you are on the phone interviewing cases instead.
The good
The hard parts
Things people don't tell you.
The Epidemic Intelligence Service, the two-year field training program at the Centers for Disease Control and Prevention, has trained more than 4,100 officers since it started. Its graduates worked on smallpox eradication, the first HIV (the virus that causes AIDS) cases and the coronavirus pandemic.
Outbreak response is the visible part, and it is a small part. The everyday work is surveillance data, cleaning records, checking definitions and writing reports. People who love the detective story and hate data cleaning do not last.
States require hospitals and labs to report every new cancer diagnosis, which builds a national record of who is getting which cancer, where. Keeping those registries accurate is a whole branch of this career.
Epidemiologists almost never get to run an experiment on people, so the entire craft is working out whether something observed in the real world is a cause or a coincidence. Study design is the skill, and it is why the master's takes two years.
Last checked September 2026. Pay figures are typical full-time annual amounts in United States dollars, based on Bureau of Labor Statistics wage data and published pay scales. They vary by state, employer and experience. Tuition is for in-state students at public schools unless the card says otherwise.
