A public health professional takes notes while working in a lab.

The public health field is filled with employment opportunities for individuals who have earned a bachelor’s degree and then completed a master’s program, which benefits students interested in a career path that matches their interests. Pursuing an advanced degree can help narrow down career options, but it’s easy to be overwhelmed by all the possibilities. Many students may be curious about the current public health job outlook, considering the increased demand for public health workers during the COVID-19 pandemic. However, the field of public health extends far beyond one virus.

The overarching goal of public health is twofold: to prevent chronic illnesses (diabetes, heart disease, and lung cancer) and infectious diseases (AIDS, tuberculosis, and hepatitis B); and to promote health and well-being using preventive methods and best practices.

Public health professionals achieve these objectives by leveraging their skills in conducting research and historical analysis, developing education programs and health policies, and promoting proactive medical practices. Individuals who are interested in pursuing an online MPH programs no GRE can benefit from learning about different public health careers and the field’s overall employment outlook.

Is Public Health a Good Career Choice?

The broad scope of the public health field and its associated advanced degree studies can accommodate a range of interests, skills, and occupational goals. As a result, the field is appealing to job seekers and bachelor’s degree graduates from nearly every professional background. Public health experts can find meaningful employment in a number of settings, including nonprofit organizations, government agencies, community-based agencies, universities, and medical facilities.

Examining the job outlook and salaries associated with various public health careers can help in deciding whether public health is a good career option.

Beyond salary and overall job stability, the nature of the work must be considered as well. Job seekers should remember this is a field that seeks to protect and improve the lives of the nation’s population through innovation, education, and medical intervention. Few career paths offer the same potential to positively impact the lives and health of countless individuals.

Public Health Job Outlook

Health care is considered one of the fastest-growing employment sectors in the U.S., with an estimated 2 million new positions (a 13% increase) projected between 2021 and 2031, according to the U.S. Bureau of Labor Statistics (BLS). While public health professions make up only a fraction of this industry segment, many research, education, and social work careers within the public health field are expected to grow consistently over the same period.

For example, the BLS expects job opportunities for health education specialists and community health workers to grow by 12% between 2021 and 2031, which is significantly higher than the 5.3% projected job growth for all occupations. This positive outlook is largely the result of rising health care costs, global initiatives, workplace safety campaigns, a need to replace workers who are transferring or retiring, and increased public awareness of health and wellness issues at the national and local levels. Additionally, COVID-19 has shown the nation that pandemic preparedness (a public health issue) is of the utmost importance.

Concerns over chronic illnesses, infectious diseases, and mental health have also created a significant demand for public health workers, further solidifying the field’s job outlook. Every prevention campaign, policy proposal, and health study requires professionals with a variety of skill sets and areas of expertise, from research and analysis to public outreach and content creation.

Public Health Salary

The salaries of public health workers vary widely depending on the position they hold, as many high-level research and administration roles require specialized training and a long history of work experience. For example, in 2021 health educators and community health workers had a median annual salary of approximately $48,900, according to the BLS. By comparison, health care administrators had a median annual salary of around $70,300, per November 2022 data from the compensation website Payscale.

While most public health professionals are primarily concerned with making a difference in the lives of people and their communities, there are plenty of opportunities to secure a competitive public health salary. But before individuals submit their job applications, they should spend some time learning about the history, career opportunities, education requirements, and relevant skills that can help them stand out to potential employers.

4 Reasons to Pursue Public Health Careers

A career in public health can prove rewarding for numerous reasons. Consider just a few of the primary draws.

1. Provides an Opportunity to Impact Lives on a Wide Scale

Public health professionals strive to prevent large-scale public health issues, including pandemics, environmental hazards, and other widespread health concerns. And when crises do occur, public health professionals help mitigate the impact and develop strategies to avoid a resurgence. In this way, public health professionals can have a direct impact on countless lives.

2. Encompasses a Variety of Roles

Public health is a field that offers ample opportunities for scientists and clinicians, but it also has openings for educators, social workers, and a host of other professionals. In other words, there are numerous ways to channel a passion for public health into a rewarding, sustainable career.

3. Job Outlook Is Promising

In the wake of COVID-19, awareness of public health is at an all-time high. As communities work to avert future epidemics and outbreaks, there’s great job security for public health professionals — and plenty of opportunities for those looking to enter the field.

4. Competitive Salaries

Most people get into public health because they want to make a difference. Even so, there are opportunities to earn generous salaries in a number of roles.

Public Health Careers

Pursuing a career in public health comes with a variety of benefits for aspiring students and established professionals alike, as the field’s wide scope can provide significant occupational mobility. Beyond the career opportunities, the public health sector uniquely affords opportunities for passionate individuals to make a difference in the community, domestically and abroad.

This career path is ideal for those who want to tackle existing and emerging health issues in their areas, solve complex global problems, and advocate for sustainable health care solutions. While master’s-level public health education may appeal to students with a strong desire to help others, it’s also a valuable avenue for professionals interested in making a career change.

Individuals curious about what they can do with a master’s in public health can explore the following career paths, which illustrate the strong public health job outlook.


Public health research uses the same systematic methodology and technical skills employed by scientists in other fields. Public health specialists test lab samples, investigate diseases and infections, and analyze test results to draw concrete conclusions about the hazards they’re studying.

Scientists in the public health sector primarily work in laboratory or hospital settings, which may be familiar to microbiologists, geneticists, agronomists, and other research-centric specializations. This allows scientists to pivot from their current field of study into any of several areas of public health with little to no retraining required, though a Master of Public Health (MPH) degree can streamline the transition. Important research-based public health careers include the following.

  • Epidemiologist: Collect and analyze data on communicable diseases and chronic illnesses to identify the root causes and distribution patterns of public health issues. Communicate these findings to other public health professionals and policymakers so solutions can be developed.
  • Environmental scientist: Leverage natural science knowledge to protect human health and the environment by studying pollution, natural disasters, and industrial practices. Collect and compile environmental data from samples of soil, water, air, and other materials for analysis to determine which are threats to the environment and human health.


Public health educators develop and implement strategies to promote healthy behaviors and spread awareness about diseases, hereditary risk factors, mental health, and environmental hazards. Their work relies on the same teaching methods that educators in other fields use, such as problem-based learning techniques, direct instruction, and social cognitive theory. Public health education often involves distilling complex ideas into easy-to-understand resources that can be widely distributed, such as educational materials on reproductive health, nutrition, and communicable diseases.

Although the daily responsibilities of public health educators differ from teachers in classroom environments, the core concepts motivating their health promotion efforts are quite similar. Earning an advanced degree in public health can help fill in the gaps, exposing educators to the subject matter, hard skills, and learning outcomes at the heart of this field. The job outlook for public health educators includes occupations such as:

  • Health education specialist: Inform communities at the local and national levels about health risks and available health care services and programs. Be at the forefront of developing materials and educational programs that teach people about critical health topics and preventive health care best practices. Serve as an advocate for improved health-related resources and programs.
  • Social worker: Identify people and communities in need of support to address health disparities and solve everyday issues that impact their well-being. Facilitate access to information on community resources such as food stamps, child care, health care, and more.

Medical Professionals

Medical professionals add substantial value to the public health sector because their expertise supports social programs, community outreach efforts, and health care policy development. Doctors, nurses, hospice workers, and other trained caregivers can leverage their firsthand experience to support state and federal initiatives and improve existing health programs.

Transitioning to a public health career enables medical professionals to shift their focus from individual patients to large populations, allowing them to have a wider impact on general health and wellness. Nearly all public health subfields rely on the clinical knowledge of traditional care providers to inform their research and education strategies, identify emerging threats, and guide their advocacy for effective health legislation. The public health job outlook for medical professionals covers a range of occupations, including:

  • Public health analyst: Implement and coordinate health programs and policies that facilitate effective solutions to public health issues and health disparities in underserved communities. Gauge the effectiveness of programs using in-depth analytical research that yields actionable insights. Assist in creating pamphlets, articles, and infographics that present key data insights in a way that is easy for the public to understand.
  • Medical and health services manager: Plan and direct medical services at treatment facilities, private practices, or public health organizations to stay compliant with changes in health care laws and policies. Develop improvements and efficiencies designed to cut costs, streamline processes, and enhance the patient experience. Recruit, hire, and train nurses and other frontline medical workers. Conduct or oversee a variety of administrative tasks such as scheduling, bookkeeping, and filing.


Skilled mathematicians can pursue any of a variety of career opportunities within the public health field, as organizations around the world depend on statistical analysis and modeling techniques to create compelling, data-driven health studies and education initiatives. Public health mathematicians use their analytical skills to answer important research questions and predict how infectious and tropical diseases will spread in populations.

The insights generated from the work of mathematicians allow medical professionals to create effective intervention strategies and remain proactive when new health risks are identified. However, these professionals do a lot more than just crunch the numbers; public health mathematicians are heavily involved in designing new studies and research methods to ensure proper information is collected. Common math-focused public health jobs include the following.

  • Biostatistician: Analyze data and apply statistical techniques to generate actionable intelligence about behavioral health and real-world issues, like the spread of diseases and the efficacy of medical treatments. Use data to make informed predictions so appropriate actions can be taken to curb the spread of diseases and send medical resources to where they are needed most.
  • Survey researcher: Design and administer public health surveys to gather information on the prevalence of chronic illnesses, health disparities, and other health-related topics. Analyze data using statistical software to extract meaningful insights about survey responses.

Specialists from almost every professional background have something valuable to offer the public health field, from technical skills and experience to general knowledge of specific health issues. Students who haven’t yet begun their careers are also essential to the growth of the public health sector since they can contribute fresh insights and perspectives to help improve health services. However, the type of work individuals can expect to perform largely depends on where they’re employed; every workplace prioritizes different activities and outcomes.

Where Do Public Health Professionals Work?

As the world grows increasingly interconnected, the success of health initiatives will continue to rely on the cooperation of public hospitals, private practice care providers, nonprofit organizations, and government entities. Each of these workplaces operates in its own sphere of influence despite the parallels in their public health objectives, which may appeal to students and experts looking to narrow down their career choices. The public health career outlook shows promise for professionals who want to work in a variety of settings.

Government Agencies

Government agencies leverage their administrative authority to enact public health policies and ensure private companies remain compliant with laws and regulations. Working for a government agency gives public health professionals access to cutting-edge technologies and sensitive information that may not be widely available. Each federal- and state-run hospital and health department has its own operational scope and funding limitations, though most institutions have significant resources at their disposal.

Almost all public health agencies in the U.S. fall under the purview of the U.S. Department of Health and Human Services, including the following:

  • Centers for Disease Control and Prevention (CDC)
  • Food and Drug Administration
  • National Institutes of Health

Private Sector Companies

While privately owned and operated corporations are beholden to their investors and shareholders, they still play a crucial role in the public health field. For-profit companies invest significant capital in medical research and studies in epidemiology to develop new treatments and health care technologies. They also provide direct medical services that help individuals identify and address chronic health issues and communicable diseases.

Additionally, the private sector relies on occupational health specialists to ensure their workplaces are safe and compliant with existing laws and regulations. Although this employment sector is more concerned with treating existing ailments than supporting preventive initiatives, it’s been responsible for important breakthroughs in immunization and cancer screenings, and is a significant part of the bright public health job outlook. Some examples of private sector companies that contribute to public health are:

  • Pfizer
  • Medtronic
  • Laboratory Corporation of America Holdings (commonly known as Labcorp)

Nonprofit/Nongovernmental Organizations

Unlike for-profit companies, nonprofit organizations (NPOs) and nongovernmental organizations (NGOs) operate with the sole purpose of addressing public health and workplace safety issues, regardless of financial gain. Most nonprofits are independent of government agencies, though they regularly collaborate on health promotion initiatives, awareness campaigns, and research programs.

NGOs and NPOs conduct research, develop social programs, promote health services, and advocate for health care policies that support underserved communities. Professionals in this employment sector are more concerned with improving living conditions for people all over the world than with securing an above-average salary, though there are plenty of opportunities to earn a competitive pay rate. Examples of public health NGOs are:

  • World Health Organization (WHO)
  • International Society for Infectious Diseases
  • American Cancer Society

A Brief History of Public Health

The concept of public health in its most elemental form has existed for thousands of years. U.S. public health policy reaches back to the 1798 Act for the Relief of Sick and Disabled Seamen, which sought to protect the American public from the spread of diseases from other countries. The U.S. Public Health Service Commissioned Corps and the U.S. Public Health Service were later authorized to investigate diseases, sanitation issues, water supply protections, and sewage disposal methods.

In 1946, the Communicable Disease Center (later renamed the CDC) was formed, and that organization participated in the planning of the WHO. A core component of the modern public health landscape remains: uniting professionals from a range of unique workplaces, backgrounds, and specializations to protect the health of all people and ensure communities have access to the medical services they need.

What It Takes to Pursue Public Health Careers

One of the best ways to take advantage of the promising public health job outlook is to earn an advanced degree that’s relevant to the field. The online MPH no GRE at Regis College provides students and established professionals with the knowledge, expertise, and technical skills needed to pursue any of a range of career paths in the public health space, from health administrator to maternal and child health advocate and far beyond.

Online MPH majors at Regis choose from two distinct concentrations: Epidemiology and Health Policy and Management. Coursework in both concentrations focuses on skills that align with many different in-demand public health roles and areas of expertise.
