Public Health Major

The Public Health Major is dedicated to preventing disease, prolonging life, and promoting the health of entire populations through organized societal efforts. Integrating multidisciplinary approaches such as epidemiology, biostatistics, environmental health, and policy management, it cultivates professionals capable of identifying health risks, formulating intervention strategies, and improving population health outcomes. Exploring the Public Health Major is the key pathway to engaging in disease prevention and control, health promotion, addressing global health challenges, and contributing professional expertise to “Healthy China” and global public health security.

1. Introduction to the Public Health Major

Public Health is the science and art of preventing disease, prolonging life, and promoting health through “organized societal efforts.” It focuses on population health rather than individual treatment, with its core mission being to apply multidisciplinary methods—including epidemiology, biostatistics, environmental health sciences, health policy and management, and social and behavioral sciences—to identify the root causes of health problems, and to develop and implement interventions to improve the health status of entire populations. This major serves as the cornerstone for addressing public health challenges such as infectious diseases, chronic illnesses, and environmental threats, and is a core supporting discipline for the “Healthy China” strategy.

5. Employment Rate and Industry Trends for the Public Health Major

Employment Rate Characteristics

“Inelastic Demand, Significantly Policy-Driven”: Following the COVID-19 pandemic, global investment in public health system development has increased, leading to stable, long-term demand growth. However, core positions within the system (e.g., in disease control) are subject to staffing quota and budgetary constraints.

“Rising Educational Requirements”: Master's degrees or higher are commonly required for specialized technical positions in first- and second-tier cities and in institutions at or above the provincial level.

“Licensure is Mandatory for Practice”: Working as a public health physician requires passing the National Public Health Physician Qualification Examination.

“Moderate Starting Salaries with High Stability”: Starting salaries in government and public institutions are not high but offer stability; starting salaries in pharmaceutical companies and consulting firms are more competitive.

Industry Development Trends

Implementation of the “Big Health” and Prevention-First Strategy: The focus of work is shifting from “centered on treating illness” to “centered on people's health,” promoting disease prevention, health promotion, and early intervention.

Informatization and Intelligence in Public Health: The development of infectious disease surveillance and early warning systems, the integration of multi-source health big data, and AI-assisted decision-making have become key priorities, creating demand for interdisciplinary talent proficient in both public health and data science.

Emerging Infectious Diseases and Global Health Security: There is a continuous rise in the need for capabilities in pathogen surveillance, vaccine R&D and evaluation, border quarantine, and global collaboration.

Chronic Disease Prevention and Control and Response to an Aging Population: Community-based comprehensive prevention and control of chronic diseases such as cardiovascular disease, diabetes, cancer, and Alzheimer's disease, along with the construction of long-term care systems, have become core tasks.

Environmental and Health Risk Governance: Increased focus on health risk assessment and management related to the health impacts of climate change, microplastic pollution, and emerging pollutants.

Building Resilience in Public Health Systems: Strengthening primary-level public health networks, emergency supply reserves, and cross-departmental coordination mechanisms to prepare for potential future public health emergencies.
