Public Health Salaries

The field of public health contains a lengthy list of long-standing and emerging roles. Even though both jobs fall under the general umbrella of public health, someone working to promote immunizations in low-income communities will have a very different job than the head of a task force in charge of distributing food and water in a disaster area. As such, earning potential varies widely between careers and subindustries. Use the table below to get more information about salaries in different public health careers.

Can I Be a Public Health Professional?

Before undertaking an educational program in public health, students should determine whether the profession is a good fit for their overall interests and career goals. A self-examination of experience, skills, knowledge, personal interests, and professional objectives can help you decide which program or career path to pursue. Here are some things to consider:

Skills and Tools of the PH Professional

The Council on Linkages Between Academia and Public Health Practice has developed a series of eight core skills for the practice of public health. These core competencies have been integrated into public health degree programs and serve as the starting point for working in the field. In general, public health professionals should have mastery in areas such as:



Analytical and assessment skills

Professionals in public health need the ability to describe community health factors, use quantitative and qualitative data (e.g. vital statistics) for analysis, and implement information technology to make evidence-based decisions.


Ability to develop policies and programs

Individuals should understand how to identify options for public health policies (e.g. immunization programs), as well as how to use public health informatics to develop, administer, and evaluate public health services and programs. It's also important to understand how diversity factors—such as language, race, and culture—impact health policies and outcomes.


Communication skills

Clear communication—both verbally and in writing—is critical in public health. Professionals must be able to facilitate discussion among community stakeholders and effectively convey information through various media, such as press releases or reports.


Technical and scientific knowledge

Using evidence-based research requires strong fundamental knowledge in the sciences that are vital to public health, such as epidemiology and biostatistics.


Financial skills

To effectively allocate funds and resources, professionals need a solid understanding of budgeting, funding procedures, and financial management.

Tools / Technology


CDC Wonder; SQL; Microsoft Access

Public health professionals use database software to collect, maintain, analyze, and evaluate data from research and public health programs.



An electronic health records system used to organize patient records, safeguard patient safety, and foster communication between public health professionals.


World Health Organization HealthMapper; Epicenter Software Epilog

Analytical health monitoring software is used to collect, manage, and analyze health-related data.



Geographic information systems software, also known as mapping software, creates visual representations of data (such as disease outbreak patterns) to help in making decisions about program planning, implementation, and evaluation.

Public Health Degrees

Public health programs are offered at all degree levels. For an idea of what to expect, each degree level is outlined below:

PH Certificate Programs

Public health intersects with multiple disciplines, from nursing to education to administration, making career transitions in the field a relatively seamless process. For some, the MPH is the educational entry point for a career, but an advanced degree is not always necessary. Instead, some choose a certificate program as an alternative educational pathway.

Certificate programs provide concentrated instruction in the foundations of public health, epidemiology, environmental health, community health, biostatistics, and health systems. They are designed for working professionals and typically require 15 credit hours to complete. Some programs may include additional course specializations in areas such as gerontology, health education, bioethics, and health communication. Depending on the university, certificate students may be eligible to take the Certified in Public Health (CPH) examination from the National Board of Public Health Examiners after completing their coursework.

PH Concentrations

Many MPH students choose a specialization to gain skills and knowledge in a particular area of interest. Most universities offer a range of options. Below is a sample of popular MPH specialties:

  • Biostatistics
    Biostatistics blends mathematical principles and statistical theory for research into public health, environmental health, biology, medicine, pharmaceuticals, and other areas. Leveraging techniques from multiple disciplines, such as computational biology and computer science, biostatisticians seek to identify community health trends, determine disease risk factors, or analyze drug effectiveness.

  • Environmental health
    Environmental health is the study of how environments—both natural and man-made—influence and impact population health. It calls on multiple disciplines, including environmental epidemiology, community-based environmental health, sustainability, and global ecology.

  • Epidemiology
    Epidemiology focuses on identifying health trends in populations, researching the cause of diseases, studying risk factors, and developing methods to protect community health. Applying statistical principles to behavioral, environmental, social, and genetic factors, epidemiologists design and conduct studies that are used for health policy program development.

  • Global health
    Global health is the study of health populations throughout the world, especially in underrepresented and underserved populations. Professionals in this area consider how risk factors are impacted by socioeconomic, cultural and policy factors. Global health researchers work to improve access to healthcare, improve health standards, and advocate for healthy behaviors.

  • Health policy and management
    Health policy and management focuses on the delivery of quality care to individual patients and communities. Improving access to underserved populations, developing streamlined approaches to patient care, and reducing healthcare costs are essential components of this career.

  • Health promotion and communication
    The essence of health promotion and communication is finding ways to educate and support underserved populations, such as those with limited access to medical services. Health educators study issues facing communities (e.g. poor nutritional behaviors) and work to develop and implement educational programs to improve outcomes.

  • Maternal and child health
    A growing subfield of public health, maternal and child health deals with the unique health needs of women, infants, and children. In this area, public health professionals may focus on reproductive health, pregnancy, infant mortality, or child development.

PH Certifications

Typically, national certification or licensure is not required for public health professionals. However, some states do require individuals in certain health-focused careers, such as environmental health, to be licensed. Credentials and certifications are specific to individual public career paths or areas, such as health education or epidemiology, and are usually voluntary. Example certifications include the following:

  • Certified Health Education Specialist (CHES)
    The National Commission for Health Education Credentialing offers the CHES credential for health education professionals who hold a bachelor's, master's, or doctoral degree in a health education field, such as community health education or school education, and who pass a certification examination.
  • Certified in Public Health (CPH)
    Offered by the National Board of Public Health Examiners, the Certified in Public Health credential confirms knowledge of current public health topics and is designed for individuals with a graduate degree in public health or an undergraduate degree with significant experience in public health.
  • Certified Public Health Administrator (CPHA)
    The Public Health Practitioner Certification Board sponsors the CPHA credential for public health administration professionals. It requires a bachelor's degree and at least three years of administrative and supervisory experience.
  • Master Certified Health Education Specialist (MCHES)
    The National Commission for Health Education Credentialing also offers the advanced MCHES credential for individuals who have worked for at least five years as an active Certified Health Education Specialist, or who hold a master's degree or higher in health education, along with five years of experience as a health education specialist.

Places of Employment

Careers in public health are available at the local, state, federal, and international levels, and cut across every industry specialization. For example, there are opportunities for research, public policy development, advocacy, education, and hands-on patient care in both public and private institutions.
