The social and economic implications of an aging population are increasingly apparent in many industrialized nations. With people in 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 healthcare 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.
- Declines in the working-age population are resulting 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.
The Decline in the Working-Age Population
A rapidly aging population means fewer working-age people are (and will) participating 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.
Many countries compensate through immigration to keep their labor forces well-supplied. While countries like Australia, Canada, and the U.K. attract more highly skilled immigrants, integrating them into the workforce can be challenging because domestic employers may not recognize their credentials and work experience, especially if they were obtained in other countries.
Fast Fact
The World Health Organization estimates that 80% of older adults will live in low- and middle-income countries in the future.
Increase in Healthcare Costs
Given that demand for healthcare rises with age, countries with rapidly aging populations must allocate more money and resources to their healthcare 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 healthcare outcomes improve when they increase spending.
The healthcare sector in many advanced economies faces similar issues, including labor and skills shortages as well as 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 older adult populations 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 healthcare 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, 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. Other countries with large percentages of older adults include Italy and Finland.
What Part of the World Has the Youngest Population?
Most of the world’s youngest populations are found in Africa. Having a young population can be both an opportunity and a challenge for nations.
How Can Countries Deal with Aging Populations?
Countries can explore different policies to adapt to economic shifts due to aging populations. A common proposal set forth includes delaying the retirement age, 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 increasing 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 healthcare 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 possible paths to adapt to these and other economic shifts.
