A Landmark Study of the Global Health Workforce
In a comprehensive analysis published in The Lancet Public Health, researchers have unveiled the most detailed picture yet of the global health workforce. The study, based on Global Burden of Disease (GBD) 2023 estimates, provides the first sex-disaggregated data across 20 health worker cadres in 204 countries and territories from 1990 to 2023. It also includes the first global estimates of community health workers, a vital but often undercounted segment of the workforce.
The findings are both encouraging and alarming. On one hand, the health workforce has nearly tripled over the past three decades, growing from 40.9 million to 122.1 million workers. On the other, the world still faces a shortage of 34.4 million health workers needed to achieve moderate levels of universal health coverage (UHC)—defined as ensuring all people can access essential health services without financial hardship.
Women: The Backbone of Health Systems
Women have been the primary drivers of this expansion, accounting for 71.4% of the growth since 1990. By 2023, they represented 68.9% of all health workers globally. This dominance is particularly pronounced in nursing and midwifery, where women make up the vast majority of the workforce. However, the study reveals a persistent gender disparity: women remain underrepresented in higher-paid and more senior positions, such as doctors and specialists, while being overrepresented in lower-paid roles like community health workers and nurses.
This gender imbalance has significant implications for health systems. Despite their numerical majority, women often face barriers to career advancement, lower wages, and less job security. Addressing these inequities is not just a matter of fairness—it is essential for building resilient health systems capable of meeting future challenges.
Persistent Shortages in Low-Income Regions
While the global workforce has grown, the distribution remains highly uneven. South Asia and sub-Saharan Africa continue to experience some of the lowest workforce densities in the world, with far fewer doctors, nurses, and midwives per capita than in high-income regions. These are precisely the areas where the burden of disease is highest and the need for universal health coverage is most acute.
The study estimates that to achieve moderate UHC targets, an additional 34.4 million health workers are required. This shortage is not just a numbers problem; it is a crisis that affects the quality of care, the ability to respond to health emergencies, and the overall health outcomes of millions of people.
Community Health Workers: A Critical but Overlooked Cadre
For the first time, the study provides global estimates of community health workers (CHWs), who numbered 7.6 million in 2023. CHWs are often the first point of contact for underserved populations, providing essential services such as maternal and child health care, disease prevention, and health education. Despite their crucial role, CHWs are frequently unpaid or underpaid, lack formal recognition, and have limited opportunities for career progression. The study highlights the need to invest in this workforce, not only by increasing their numbers but also by ensuring they receive adequate training, compensation, and support.
Policy Implications and the Path Forward
The findings underscore the urgent need for targeted investments in health workforce development, particularly in regions with the greatest shortages. Policymakers must prioritize training, recruitment, and retention of health workers, with a specific focus on gender equity. This includes removing barriers that prevent women from advancing into leadership roles, closing the gender pay gap, and creating safe and supportive working environments.
Moreover, the study emphasizes the importance of accurate data. The sex-disaggregated estimates provided by this research are essential for monitoring progress and designing effective policies. Without such data, it is impossible to identify where the gaps are and whether interventions are working.
Investing in Health Systems
Achieving universal health coverage requires more than just increasing the number of health workers. It demands a holistic approach that includes strengthening health infrastructure, ensuring a reliable supply of medicines and equipment, and implementing robust health information systems. The health workforce is the backbone of any health system, and without adequate numbers and skills, all other investments will fall short.
The Role of International Cooperation
Addressing the global health workforce shortage is a shared responsibility. High-income countries, which often recruit health workers from low-income countries, must adopt ethical recruitment practices that do not exacerbate shortages in source countries. International organizations, donors, and governments must work together to fund education and training programs, particularly in the hardest-hit regions.
Conclusion
This landmark study provides a comprehensive baseline for understanding the global health workforce and its gender dynamics. It shows that while women have driven remarkable growth, significant gaps remain. The world cannot achieve universal health coverage without addressing these shortages and inequities. The time to act is now, with targeted investments, sound policies, and a commitment to gender equality in health.
