Centenarians are on the rise: How living longer will affect society’s economics

JayDee Vykoukal, Wealth of Geeks

According to a Pew Research Center analysis of United States Census Bureau data, the number of Americans aged 100 and older is expected to more than quadruple over the next three decades. The population is projected to reach 422,000 in 2054, up from an estimated 101,000 in 2024.

These centenarians aren’t the only aging demographic on the rise. The 2020 U.S. Census count found one in six Americans is over 65, compared to less than 1 in 20 in 1920. Older populations are rising at historically fast rates.

How will these changes in the population affect our economy and social dynamics, globally and locally?

A global look at aging societies


The United States is home to the world’s second-largest centenarian population. American centenarians are primarily women (78%) and white (77%).

Japan has the world’s largest centenarian population, with 146,000 in 2024. China ranks third with an estimated 60,000. Experts predict centenarian populations will rise as countries consistently invest in life-span-extending health care and technology. With each passing year, more people than ever celebrate their 100th birthday and beyond.

While an aging population is a global economic concern, the United States remains relatively young compared to 33 other countries, primarily in Europe and Asia.

What do these statistics mean for the future of our society and economy? At an individual level, aging citizens’ families face mounting financial pressures as they tackle costs associated with health care and retirement. Federal programs like Social Security and Medicare must be adjusted to account for longer life spans that strain coverage options.

Rapid rise of 65+ population


A few factors contribute to the rise in older populations. Experts cite advancements in medical technology and health care as primary contributors to greater numbers of older citizens. Enhanced medical care extends life expectancies.

Additionally, fertility rates are declining in many developed countries. Fewer babies contribute to a smaller, younger population and percentage-wise to a larger, older population. Trend forecasts expect this pattern to continue, resulting in an even wider discrepancy among generations.

Economic implications of an aging population


The increase in centenarians and the overall aging population has several societal and economic implications. Baby boomers — those born between 1946 and 1964 — reach retirement age in large numbers, and the population of older adults further increases. Economies and industries worldwide will feel shifts as baby boomers continue to age.

One primary concern is the growing population’s strain on Social Security and health care systems. Longer lives generate a greater need for these services. However, insufficient resources cannot adequately support them. The latest Trustees report from the Social Security Administration reveals that the program will run cash deficits of $3 trillion over the next decade. This discrepancy could result in increased taxes or reduced benefits for future generations.

Another concern is the impact on the labor force and productivity. As older individuals retire, fewer workers will be available to replace them. That leads to labor shortages in some industries and decreased overall productivity.

Social implications of an aging population


An aging population can have significant social implications. With more people living longer, experts predict a greater need for long-term care facilities and support services. Support shortages burden families and caregivers, namely those who must balance loved ones’ care with full-time work. Caregivers, including relatives of aging citizens, need extra money to cover new costs.

The increase in older adults may also lead to changes in family dynamics. As people live longer, multigenerational living will continue to grow for its practical and economic benefits. Unlike some other cultures, American households are not typically accustomed to multigenerational living, which could create new challenges and opportunities for society.

As the population ages, societal norms and expectations will likely mutate. Potential systemic shifts could include an increased retirement age, new or altered healthcare policies, and overall attitudes toward seniors and aging processes.

Solutions require preparation and innovation


An aging population represents progress, but these changes require systemic preparation and action. Governments, businesses, and individuals must prepare and plan for these shifts to ensure stability and sustainability for all.

Ensuring prosperous futures for younger generations may require new policies, significant healthcare and technology investments, and renewed attitudes toward aging. Ultimately, the growing population of older adults presents challenges and opportunities that governing bodies must carefully address to support society’s well-being.
