The Longevity Dividend: The Business Case for Linking Health and Wealth
A new report from the World Economic Forum, developed in collaboration with Marsh, quantifies the economic returns of three deliberately low-tech preventive interventions across 21 countries — and the figures are substantial. Together, home safety retrofits, community physical activity programs, and expanded hearing aid access could save the world's healthcare systems more than $5.8 trillion and unlock an additional $645 billion in productivity gains by 2040.
The falls-prevention case is the clearest illustration of prevention economics at work: simple home modifications such as grab bars, stair lighting, and improved flooring could prevent nearly 400 million falls globally by 2040, generating over $5 trillion in cumulative healthcare savings against less than $400 billion in upfront investment. Because falls frequently trigger cascading complications and long-term care needs — with caregiving burdens falling disproportionately on women — prevention here also protects an estimated $363 billion in lifetime earnings that would otherwise be lost.
The second intervention, community programs promoting moderate physical activity, could prevent 8.5 million new cases of type 2 diabetes by 2040 at a cost of roughly $1–$40 per person, returning over $125 billion in productivity gains and $85 billion in healthcare savings. The third, expanded hearing aid access, could help prevent 2.4 million dementia cases and save more than $320 billion in healthcare costs.
The report's broader argument is structural: longevity is typically treated as a challenge for healthcare and pension systems, when the evidence suggests it is one of the most consequential and underestimated drivers of economic growth available — for countries with younger and older populations alike. Capturing that dividend requires linking health and financial resilience through coordinated action across governments, employers, financial institutions, and health systems.
