So you want to work in data analysis (or even epidemiology) — but you’re not sure where to start. Maybe you’re pivoting from another field. Maybe you’re fresh out of undergrad. Or maybe you’ve been in public health for a while, but you’re ready to dig into the data side of things.
Wherever you are, the good news is: there are multiple entry points, and you don’t need to have it all figured out to begin.
Here’s what I wish more people knew about breaking into these fields — including real skills, certifications, degrees, and options that don’t require a master’s degree (yet).
1. Understand What Each Field Is (and Where They Overlap)
Data Analyst:
Focuses on collecting, cleaning, analyzing, and visualizing data to support decision-making. Found across nearly every industry — including health care, finance, tech, marketing, and public policy.
Epidemiologist:
Focuses on understanding the causes, patterns, and effects of health and disease in populations. Works in government, hospitals, nonprofits, and research institutions.
Where they meet:
Epidemiologists are often data analysts — just in a health-focused context. Many start as analysts and specialize over time.
2. Start With Skills, Not Job Titles
Before chasing a title, start building foundational skills you can take into any role:
- Data analysis tools: Excel, R/R Studio, Python, SAS, or SPSS
- Data visualization: Tableau, Power BI, or even Excel charts
- Statistics & epidemiological concepts: incidence, prevalence, odds ratios, confounding, etc.
- Critical thinking & storytelling with data
If you’re starting from scratch, platforms like Coursera, DataCamp, and Khan Academy are gold for free or low-cost intro courses.
3. Explore Certifications & Short-Term Training
Don’t have time or money for a full degree yet? Consider:
- Google Data Analytics Certificate (Beginner-friendly, self-paced)
- Coursera: Epidemiology: The Basic Science of Public Health (offered by UNC)
- HarvardX: PH525.1x Statistics and R for the Life Sciences (free online)
- SAS Certification in Epidemiology & Clinical Trials
- CDC’s E-Learning Series: Principles of Epidemiology
These can boost your resume and help you figure out what area actually excites you.
4. Get Experience — Even Without a Job
Build a portfolio, even if no one’s hired you (yet):
- Analyze public datasets (check out CDC WONDER, Kaggle, or data.gov)
- Create infographics or dashboards using open data
- Volunteer for nonprofits to help with basic reporting
- Blog about your analysis process or findings (your voice matters!)
- Join public health data challenges or hackathons
5. Consider a Formal Degree — But Only If It Makes Sense
For epidemiology roles, a master’s in public health (MPH) or MS in epidemiology is often required for higher-level roles.
For data analyst roles, a degree helps, but isn’t always necessary if you can show your skills. Some analysts come from backgrounds in sociology, psychology, biology, or even English — and learn the tools later.
6. Apply to Bridge Roles
You don’t have to jump straight into “Epidemiologist” or “Data Analyst” — look for titles like:
- Public Health Analyst
- Research Assistant
- Program Evaluator
- Data Coordinator
- Surveillance Specialist
- Biostatistics Assistant
- Data Entry → QA roles
- Clinical Research Associate
Get your foot in the door, grow your skills, and move up from there.
7. Network (Yes, Even If You Hate It)
Start by joining:
- LinkedIn groups (Data Analysts of Color, Black Public Health Network)
- Slack communities (like R for Public Health, Data Analysts Hangout)
- Conferences (APHA, Society for Epidemiologic Research, etc.)
- Free webinars from the CDC, NIH, and WHO
Let people know what you’re learning and where you want to go. That’s networking, too.
8. Earning Potential: What Can You Expect to Make?
The good news? Both data analysts and epidemiologists offer strong earning potential, with plenty of room to grow — especially as you build experience and specialize.
Data Analyst (U.S. Averages)
- Entry-level: $55,000–$70,000
- Mid-level (3–5 years): $75,000–$95,000
- Senior/Lead Analyst: $100,000–$125,000+
- Specialized roles (e.g., healthcare, product, financial analytics): can exceed $130K, especially with SQL/Python skills and dashboarding expertise
Epidemiologist (U.S. Averages)
- Entry-level (MPH/MS required for most roles): $60,000–$75,000
- Mid-level (government, research orgs, NGOs): $80,000–$100,000
- Senior Epidemiologist / Supervisory roles: $105,000–$130,000+
- Consultants / Principal Investigators / International roles: $130K–$160K+
Factors that influence pay:
- Industry (tech, pharma, and consulting tend to pay more than nonprofits or local government)
- Location (remote roles can offer competitive national rates)
- Skill set (SQL, R, Python, Power BI/Tableau, epidemiologic modeling, grant writing)
- Credentials (master’s or doctoral degree, certifications, publication history)
Pro Tip: If you’re just getting started, aim to stack skills and small wins, then negotiate confidently — even for internships or first jobs. Your ability to tell stories with data is in demand.
Final Thoughts
Breaking into data analysis or epidemiology isn’t about being perfect — it’s about being curious and consistent. Start where you are. Learn a little every week. Say yes to small opportunities. Build a body of work that reflects your growth.
And most of all: don’t gatekeep yourself out of a field that needs your perspective. Data is powerful. And when used well, it saves lives.
