- Noncommunicable diseases (NCDs) are responsible for approximately 46 million deaths and 768 million years lived in poor health each year.
- Scaling access to known interventions could address about 35 percent of the global disease burden of NCDs and mental health conditions, preventing around 28 million deaths annually and adding 396 million years of healthy life globally in 2050.
- This investment in the health of society could add $11 trillion to the global economy in 2050 through a healthier and more productive labor force.
Even if a person is in excellent health, everyone knows someone—if not many people—with a noncommunicable disease (NCD), such as heart disease, diabetes, depression, or cancer. That’s no accident: As populations continue to age around the world,1 NCDs are becoming more widespread, and the current prevention and intervention efforts cannot keep up.2 Currently, NCDs are responsible for approximately 46 million deaths and 768 million years lived in poor health each year.3
Without action, this burden will rise, with estimates projecting up to 75 million deaths from NCDs—and 1.1 billion years in poor health—in 2050.4 This means the average person in 2050 will spend about 42 days per year in poor health due to NCDs. The result? A loss of independence that affects the activities of daily living; less ability to be fully engaged at work; and fewer chances to visit with friends, children, or grandchildren.
Beyond the clear human costs, the growing burden of NCDs poses a major threat to economies worldwide, creating an estimated $36 trillion drag on global GDP in 2050, equivalent to 20 percent of projected GDP. NCDs reduce the labor supply due to premature death and ill health, while also undermining productivity across entire workforces.5 Whether they are conscious of it or not, employers in all sectors are affected, as poor employee health correlates to higher absenteeism and less productivity.
At a time when investing in health is under threat due to competing priorities, society also is witnessing the transformative impact from intervening in NCDs. Australia is on track to be the first country to eliminate cervical cancer through scaling up HPV vaccination and cervical screening interventions.6 Scaling tobacco control measures in Brazil has led to a 35 percent reduction in tobacco use since 2010.7 And recent breakthrough treatments such as GLP-1s have the potential to transform metabolic health.8 Society is in an era of outstanding potential, yet with scarce funding to achieve that potential.9
In this context, the United Nations General Assembly will convene the UN Fourth High-level Meeting on the Prevention and Control of Noncommunicable Diseases and the Promotion of Mental Health and Well-being in September 2025, aiming to intensify global action toward alleviating the burden of NCDs. Transforming and improving lives and livelihoods requires stakeholders to shift from seeing healthcare as a cost to contain to viewing it as an investment in human capital. In this briefing and an upcoming report, the McKinsey Health Institute’s (MHI) analysis sizes the potential for known health interventions to bend the curve of disease burden. It also shows the economic opportunity that investing in health can bring (see sidebar, “Methodology”).
Bending the curve of disease burden by scaling what works
There is a substantial opportunity to create impact by scaling what works. Using MHI’s Prioritizing Health model, we estimated the potential health and economic benefits of expanding access to more than 220 evidence-based cost-effective interventions that target modifiable risk factors, prevention, and treatment of NCDs and mental health conditions. If scaled to ambitious yet achievable levels worldwide, these interventions could address about 35 percent of the global disease burden of NCDs and mental health conditions, preventing around 28 million deaths annually and adding 396 million years of healthy life globally in 2050. For the average person, this translates to 15 additional healthy days every year.
At the individual level, this revolutionary improvement in human health would mean that, on average, a person born in the next 25 years could live five years longer and gain seven years of healthy life expectancy. This would reverse the long-term trend of the average person spending more years in poor health than the generation before did. Beyond the personal benefits—more quality time with loved ones, the ability to work on a passion project after retirement, or staying in good health long enough to travel—a healthier population also fuels economic growth.
Good health—good investment
Improving global health isn’t just the right thing to do—it is also an excellent investment. Investing in scaling proven health interventions could also add $11 trillion to global GDP in 2050, equivalent to 6 percent of projected GDP, with every dollar invested yielding a potential return of $4.
- Better health would mean fewer short- and long-term absences from work, which could add $6.2 trillion to the global economy in 2050.
- Reducing presenteeism—when employees are at work but not fully productive—could boost productivity by $1.1 trillion in 2050.
- Preventing premature death: Better health and well-being enables people to live longer, more fulfilling lives, both personally and professionally, adding $2 trillion to the global economy in 2050.
- A healthier population would reduce the need for informal caregiving, freeing up time for caregivers to either rejoin the workforce or be more productive in their current jobs. This could contribute $1.8 trillion to GDP in 2050.
- Finally, addressing the childhood disease burden would not only protect the well-being of vulnerable young people but also improve their educational outcomes and enable future generations to grow into healthier, more productive adults. This could add $300 billion to GDP in 2050.
Scaling proven health interventions can help reduce the global cost of healthcare. Unlike many other sectors, healthcare has a unique advantage: The highest-quality care is also the least expensive, because preventing people from becoming sick in the first place costs less than treating severe illness later. Increasing access to these preventative interventions could lower the projected time the average person spends in poor health due to NCDs from 42 days annually to 33 days in 2050. For leaders of health systems, this reduction highlights the opportunity to substantially decrease the need for medical treatments, hospitalizations, and long-term care through investments in preventative care and risk reduction, thereby alleviating both the financial and operational pressures on healthcare systems.
Decision-makers always face tough trade-offs when evaluating budgets. But investing more and investing better in health can be seen as part of a comprehensive strategy that can boost other sectors and create broader economic and societal benefits. We believe the health of our people really is our greatest asset.
