The social and economic implications of an aging population are becoming increasingly apparent in many industrialized nations around the globe. With populations in places such as North America, Western Europe, and Japan aging more rapidly than ever before, policymakers are confronted with several interrelated issues, including a decline in the working-age population, increased health care costs, unsustainable pension commitments, and changing demand drivers within the economy. These issues could significantly undermine the high living standard enjoyed in many advanced economies.
Key Takeaways
- Many industrialized nations are realizing the effects of an aging population, such as a decline in the working-age population and a surge in health care costs.
- Over 20% of the population of 17 countries consists of persons 65 years or older.
- The decline in the working-age population results in a supply shortage of qualified workers.
- Nations with larger older populations depend on a smaller group of people to pay for higher health costs, pension benefits, and other publicly funded programs.
Advanced Industrialized Societies Are Growing Older
In 2020, there were 727 million people aged 65 or older. This number is expected to more than double by 2050.
The Decline in the Working-Age Population
A rapidly aging population means there are fewer working-age people in the economy. This leads to a supply shortage of qualified workers, making it more difficult for businesses to fill in-demand roles. An economy that cannot fill in-demand occupations faces adverse consequences, including declining productivity, higher labor costs, delayed business expansion, and reduced international competitiveness. In some instances, a supply shortage may push up wages, thereby causing wage inflation and creating a vicious cycle of price/wage spiral.
To compensate, many countries look to immigration to keep their labor forces well supplied. While countries such as Australia, Canada, and the United Kingdom are attracting more highly skilled immigrants, integrating them into the workforce can be a challenge because domestic employers may not recognize immigrant credentials and work experience, especially if they were obtained in countries outside of North America, Western Europe, and Australia.
Increase in Health Care Costs
Given that demand for healthcare rises with age, countries with rapidly aging populations must allocate more money and resources to their health care systems. Healthcare spending as a share of gross domestic product (GDP) is already high in most advanced economies; one challenge that advanced economies face is to ensure that when they increase spending, healthcare outcomes actually improve.
Additionally, the healthcare sector in many advanced economies faces similar issues, including labor and skills shortages and increased demand for at-home care. All of these cost escalators can make it more difficult for existing systems to handle the increased prevalence of chronic diseases, while also addressing the needs of large and growing populations of older adults.
Increase in Dependency Ratio
Countries with large populations of older adults depend on smaller pools of workers from which to collect taxes to pay for higher health costs, pension benefits, and other publicly funded programs. This is becoming more common in advanced economies where retirees live on fixed incomes with much smaller tax brackets than workers. The combination of lower tax revenue and higher spending commitments on health care, pensions, and other benefits is a major concern for advanced industrialized nations.
Changes to the Economy
An economy with a significant share of older adults and retirees has different demand drivers than an economy with a higher birth rate and a larger working-age population. For example, rapidly aging populations tend to have greater demands for health care services and retirement homes. Although this is not necessarily negative, economies may face challenges transitioning to markets that are increasingly driven by goods and services linked to older people. As advanced economies become older over the next 15 years, it remains to be seen whether immigration will fill the voids in sectors left by aging populations or whether the broader economies will have to adjust to changing demographics.
Which countries have the largest percentage of older adults?
Japan is the country with the highest proportion of its population composed of older adults, with 28.2% of people being 65 or older. Other countries with large percentages of older adults include Italy, with 22.8% of its population 65 or older, and Finland, with 21.9%.
What is the youngest population in the world?
The world's youngest countries are mostly in Africa, with Niger having the lowest median age of just 15.2 years. Having a young population can be both an opportunity and challenge for nations.
How can countries deal with aging populations?
Countries are currently exploring a number of different policies to adapt to economic shifts due to aging populations. A common proposal set forth includes delaying the age of retirement, which effectively lengthens the amount of time that individuals spend working. Other possibilities include decreasing social security benefits, in cases where there are potential deficits, and increase taxes to pay for them.
The Bottom Line
Many industrialized nations are grappling with aging populations, which often correspond with a decline in working-age adults and a rise in health care costs. These issues can cause economic strains, particularly when it means that a smaller proportion of the total population has to bear significant social safety net costs. Countries with aging economies are currently exploring a number of possible paths to adapt to these and other economic shifts.

Key Concepts Discussed in the Article:
-
Aging Population Statistics:
- The article emphasizes that industrialized nations, including North America, Western Europe, and Japan, are experiencing the significant effects of an aging population.
- Over 20% of the population in 17 countries comprises individuals aged 65 or older.
-
Magnitude of Aging Population:
- In 2020, there were 727 million people aged 65 or older globally, a number expected to more than double by 2050.
-
Decline in the Working-Age Population:
- A rapidly aging population results in a decline in the working-age population, posing challenges such as a supply shortage of qualified workers.
- This shortage can lead to adverse consequences for the economy, including declining productivity, higher labor costs, delayed business expansion, and reduced international competitiveness.
-
Immigration as a Solution:
- Many countries address the decline in the working-age population by turning to immigration to maintain a well-supplied labor force.
- Challenges in integrating immigrants into the workforce are noted, especially when credentials and work experience are from non-industrialized regions.
-
Increase in Health Care Costs:
- With age, the demand for healthcare rises, necessitating increased allocation of money and resources to healthcare systems.
- Advanced economies already face challenges in ensuring that increased healthcare spending results in improved outcomes, while also dealing with issues like labor shortages and demand for at-home care.
-
Dependency Ratio Increase:
- Nations with larger older populations depend on a smaller pool of workers to fund higher health costs, pension benefits, and publicly funded programs.
- The combination of lower tax revenue and higher spending commitments poses a significant concern for advanced industrialized nations.
-
Economic Changes:
- An economy with a substantial share of older adults has different demand drivers, leading to challenges in transitioning to markets driven by goods and services for older populations.
- The article speculates on whether immigration or broader economic adjustments will fill voids left by aging populations.
-
Global Examples:
- Japan is highlighted as the country with the highest proportion of older adults (28.2%), followed by Italy (22.8%) and Finland (21.9%).
-
Dealing with Aging Populations:
- Countries are exploring various policies, including delaying the retirement age, decreasing social security benefits in potential deficit cases, and increasing taxes to address economic shifts due to aging populations.
In conclusion, the social and economic implications of aging populations are multifaceted and require strategic planning by policymakers to mitigate potential challenges and adapt to the changing demographic landscape.
