The world is in the midst of a profound demographic transformation as countries in Europe, North America, and parts of Asia grapple with the potent combination of an aging population and declining birth rates. Meanwhile, countries in other parts of the world, such as Africa, are seeing their populations surge. The New York Times documented these trends in a 2023 piece that shows how the world is projected to change in the coming decades. These demographic shifts will have significant impacts on the retirement systems of countries that are rapidly aging and may force nations to rethink how they structure and fund their retirement plans.
This demographic shift is being driven by the aging of populations in many advanced economies. With longer life expectancies and lower birth rates, many of these countries are experiencing an increasing proportion of elderly citizens compared to their working-age populations. The U.S. Census Bureau projects that by 2034, there will be more senior citizens than children for the first time in American history. This transition has major implications for the sustainability of retirement systems, as it places greater financial pressure on governments, individuals, and employers to provide for retirees.
One of the most immediate challenges resulting from changing demographics is the strain on government-sponsored pension and healthcare programs. As the elderly population grows, demands on social safety nets increase. With this new strain on resources, governments and municipalities must allocate a larger share of their budgets to support retirees, potentially diverting resources from other essential services for younger generations like education, infrastructure, and healthcare. Getting ahead of these trends will help ensure the long-term viability of these vital programs and manage costs for future generations.
For instance, long-term care costs are largely not planned for across America today. Unlike retirement income, where governments, employers, and individuals all play an important role, there is no logical, comprehensive effort to pay for our own long-term care costs during our working lives. As a result, Medicaid pays for roughly half of these costs when seniors can’t afford the extraordinarily costly services that one faces when lives are impacted by conditions like Alzheimer’s or dementia. This, in turn, results in higher spending on Medicaid. With longer lives, we should expect higher utilization and costs in the future. Unless we acknowledge the challenge and adopt a sound funding strategy, the burdens will be left to future generations.
Shifting demographics also affect the workforce and economic productivity. As the prime-age labor force shrinks in proportion to the elderly population, there may be labor shortages and reduced economic growth. This, in turn, can impact the ability of individuals to save for retirement and employers and governments to contribute to retirement plans. Some recent data suggests that the increasing retirements of Baby Boomers, especially after the pandemic, have contributed to the tight labor market, but that prime-age labor force participation has increased to fill those gaps as a result.
An aging population has also impacted individual retirement planning. Longer life expectancies mean that individuals must save more for retirement to ensure they do not outlive their savings. Yet, we continue to accept that roughly half of workers are not saving through paycheck deduction at work, despite knowing how effective it is at increasing individual savings.
The National Institute on Retirement Security has documented the growing burden of retirement, partly caused by longer lifespans and higher health costs. Retirement security can be particularly challenging for those in younger generations who may face stagnant wages, high housing costs, and student loan debt. Given these factors and changes in employer-sponsored retirement plans since the advent of the 401(k), the traditional model of working until a certain age and then retiring with a pension is becoming more challenging.
The changing demographics detailed in The New York Times piece highlight the critical connection between demographic shifts and retirement security. As populations age and birth rates decline in countries that have historically provided strong retirement benefits, governments, individuals, and employers must grapple with the financial, economic, and social implications of this transformation. Addressing these challenges will require innovative policy solutions, increased financial literacy, and a proactive approach to expanding access to frictionless individual retirement savings programs. Ensuring retirement security for all in the face of changing demographics is not only a matter of economic stability, but also a reflection of societal values and commitments to the well-being of future generations.
