The world’s population is ageing at an unprecedented rate. The same problems present in the early 2020s will only grow in 2025. While increased longevity is a positive development, it also presents significant economic and social challenges, particularly for countries with rapidly ageing populations. This article draws upon a variety of research papers and articles to provide a comprehensive analysis of the economic and social risks associated with an ageing population and examines the factors that contribute to a country’s vulnerability to the risks of population ageing, ultimately identifying those most at risk.
Factors Contributing to Risk
Several factors contribute to a country’s economic and social vulnerability to an ageing population:
| Factor | Description |
|---|---|
| High proportion of elderly people | A high proportion of elderly people in the population increases the dependency ratio, placing a greater burden on the working-age population to support retirees through pensions, healthcare, and social security1. |
| Low birth rates | Low birth rates exacerbate the challenges of an ageing population by reducing the number of people entering the workforce and contributing to the economy2. |
| High dependency ratios | The dependency ratio, the ratio of non-working-age people (both young and old) to working-age people, is a key indicator of the economic strain caused by an ageing population. High dependency ratios mean fewer workers support a growing number of dependents3. |
| Weak social safety nets | Countries with weak social safety nets for the elderly are more vulnerable to the economic and social consequences of population ageing, as retirees may face poverty, inadequate healthcare, and social isolation. Regional spending on social safety nets is lowest in emerging and developing Asia and sub-Saharan Africa. For example, in sub-Saharan Africa, Lesotho spends almost 5.5 percent of GDP on social safety nets, whereas Cameroon, Guinea-Bissau, and South Sudan spend less than 0.2 percent4. |
| High levels of ageism | Ageism can lead to discrimination against older adults in employment, healthcare, and social participation, further exacerbating the challenges of an ageing population5. |
| Low labor force participation among older adults | Low labor force participation among older adults reduces the potential workforce and can contribute to economic decline6. |
Countries Most at Risk
Based on the factors outlined above, several countries appear to be particularly vulnerable to the economic and social risks of an ageing population:
1. Japan: Japan has one of the oldest populations in the world, with those aged 65 or older accounting for nearly 30 percent of the population7. The country also has one of the lowest birth rates in the world8. This combination of factors has led to a high old-age dependency ratio, placing a significant strain on the economy and social security system9. Japan faces the challenge of supporting a growing elderly population with a shrinking workforce and rising healthcare costs.
2. South Korea: South Korea is experiencing a rapid demographic shift, with a low fertility rate and increasing life expectancy10. The country is projected to become a “super-aged” society by 2025, with one in five people aged 65 or older11. This rapid ageing poses significant challenges to the economy and social welfare system12. South Korea must address the potential for increased elderly poverty and strain on social support systems.
3. Italy: Italy has the second-oldest population in the world, with 24.3 percent of the population aged 65 years and older in 202413. The country also has a low fertility rate, further contributing to the challenges of an ageing population14. The economic and social consequences of this demographic trend are significant, with a shrinking workforce and increasing healthcare costs15. Italy faces the risk of declining economic productivity and challenges to the sustainability of its social security system.
4. Spain: Spain is another European country with a rapidly ageing population. In 2023, 20 percent of the population was aged 65 or older16. The country has experienced one of the fastest demographic ageing processes in the last decade16. This trend poses challenges to the sustainability of the pension system and the overall economy17. Spain must address the potential for reduced economic growth and increasing inequality.
5. Germany: Germany has a high proportion of elderly people, with 22.79 percent of the population aged 65 and above in 202318. The country also faces a declining labor force and increasing healthcare costs associated with an ageing population19. Germany must find ways to maintain economic competitiveness and ensure the adequacy of its social security system.
Economic Risks
The economic risks of an ageing population are multifaceted:
- Shrinking workforce: As the proportion of elderly people increases and birth rates decline, the workforce shrinks, leading to labor shortages and slower economic growth20. This can also lead to reduced tax revenue and potential difficulties in funding public services.
- Increased healthcare costs: Ageing populations require more healthcare services, leading to increased healthcare expenditures and potential strain on healthcare systems21. This can create budgetary pressures and potentially lead to rationing of healthcare resources.
- Pension system strain: A growing elderly population puts pressure on pension systems, as fewer workers contribute to support a larger number of retirees22. This can lead to unsustainable pension systems and potential cuts in benefits for retirees.
- Lower productivity: While older workers can bring valuable experience and skills, some studies suggest that ageing workforces may be associated with lower productivity growth23. This can impact economic competitiveness and potentially lead to lower living standards.
- Reduced innovation: Some research indicates that companies with older workforces may be less likely to adopt technological changes and invest in innovation23. This can hinder economic dynamism and long-term growth prospects.
- Low labor force participation among older adults: Many older workers struggle to hold on to their jobs or find new employment. On average across OECD countries, less than 50% of workers aged 55-59 are still in the same job five years later. This ranges from over 70% in Norway and Iceland to around 30% in Türkiye, Austria and Korea24.
- Impact of migration: Population ageing will gather pace in Spain over the coming decades, growing at a faster rate than in the EU and the euro area as a whole, despite the strong net immigrant inflows17.
Furthermore, economic decline can create a vicious cycle, leading to reduced social spending, increased poverty among older adults 12, and greater strain on families and communities. As economic conditions worsen, governments may face pressure to cut social welfare programs, exacerbating the challenges faced by older adults and potentially increasing social inequalities25.
Social Risks
In addition to economic risks, ageing populations also pose social challenges:
- Increased social isolation: Older adults, particularly those living alone, may experience increased social isolation and loneliness, leading to negative health and well-being outcomes. In Japan, for example, the proportion of men and women aged 65 and above living alone has increased significantly in recent decades26.
- Elderly poverty: Inadequate social safety nets and rising healthcare costs can contribute to poverty among older adults12. This can lead to social exclusion, reduced access to essential services, and poorer health outcomes.
- Intergenerational conflict: As the dependency ratio increases, there is a potential for intergenerational conflict over resources and social priorities27. This can manifest in tensions between generations regarding the allocation of public funds and social support programs.
- Ageism and discrimination: Ageism can lead to discrimination against older adults in various aspects of life, including employment, healthcare, and social participation28. This can limit opportunities for older adults and contribute to social exclusion.
- Ageism in specific countries: Perceptions of discrimination against older people are particularly high in Eastern European countries, with over 60 percent of people in Bulgaria, Czech Republic, Hungary, and Romania reporting widespread or fairly widespread discrimination27.
It is important to note that cultural values can influence the prevalence of ageism. Collectivistic countries, which emphasize group cohesion and harmony, tend to have less age bias than individualistic countries, which prioritize independence and individual achievement29.
Technological Solutions
While population ageing presents significant challenges, it also creates opportunities for technological innovation. Japan, for instance, is actively exploring how technology can help address the needs of its ageing society. This includes developing robots and assistive devices to support older adults in their daily lives, as well as utilizing technology to improve healthcare and long-term care services26.
Business Opportunities
The ageing population presents a significant opportunity for businesses in various sectors. With a 5-10 year time horizon, the following areas are likely to see increased demand:
- Healthcare and wellness: As the elderly population grows, the demand for healthcare and wellness services will increase. This includes medical clinics, home healthcare services, and wellness centers specializing in senior care. Businesses can offer a range of services, from physical therapy and rehabilitation to mental health services and preventative care32.
- Senior-friendly housing: With a growing need for assisted living facilities and retirement communities, businesses can develop senior-friendly housing options that offer a mix of independence and necessary care. These facilities can provide a safe and supportive environment for older adults while catering to their specific needs and preferences33.
- Medical equipment and assistive technologies: The demand for medical equipment and assistive technologies will rise as the elderly population requires more support in their daily lives. This includes mobility aids, home monitoring devices, and communication technologies that can help older adults maintain their independence and quality of life34.
- Personal and lifestyle services: Businesses can offer personal services such as home cleaning, meal delivery, and personal shopping to cater to the needs of older individuals, especially those with limited mobility. These services can provide convenience and support, allowing older adults to age in place comfortably33.
- Agetech: Agetech, a rapidly growing sub-sector of healthcare, offers opportunities for businesses to develop innovative solutions that address the challenges of an ageing population. This includes smart devices, wearables, and robotics that can assist with daily tasks, monitor health conditions, and provide companionship35.
Conclusion
Population ageing is a global phenomenon with significant economic and social implications. Countries with high proportions of elderly people, low birth rates, weak social safety nets, and prevalent ageism are particularly vulnerable to these risks. Addressing these challenges requires comprehensive strategies that promote economic growth, strengthen social security systems, and foster inclusive societies that value and support older adults.
In addition to the solutions mentioned earlier, active ageing policies can play a crucial role in mitigating the negative impacts of an ageing population. Policies that promote healthy ageing, lifelong learning, and employment opportunities for older adults can contribute to economic and social well-being30. For example, promoting lifelong learning can help older adults acquire new skills and adapt to changing labor market demands, while ensuring access to quality healthcare can enable them to maintain their health and independence31.
Summary
The research highlights the complex interplay of demographic, economic, and social factors that contribute to a country’s vulnerability to the risks of an ageing population. While increased life expectancy is a positive achievement, it also presents significant challenges that require proactive and comprehensive policy responses.
Key findings include:
- Regional variations: East Asian countries, particularly Japan and South Korea, face acute challenges due to their rapidly ageing populations and low birth rates. Southern European countries, such as Italy and Spain, also face significant risks due to low fertility rates and increasing longevity. These regional variations highlight the need for tailored policy responses that consider specific demographic and socioeconomic contexts.
- Economic consequences: Ageing populations can lead to shrinking workforces, increased healthcare costs, and strain on pension systems. These economic consequences can have far-reaching impacts on economic growth, productivity, and living standards.
- Social implications: Social risks include increased social isolation, elderly poverty, and potential intergenerational conflict. These social implications can undermine social cohesion, well-being, and equality.
Addressing these challenges requires a multi-pronged approach that includes:
- Promoting economic growth: Policies that encourage innovation, investment, and labor force participation among older adults can help mitigate the economic consequences of ageing. This may involve creating incentives for businesses to hire and retain older workers, promoting entrepreneurship among older adults, and investing in education and training programs to enhance their skills and employability.
- Strengthening social security systems: Ensuring adequate pensions, healthcare, and social support for older adults is crucial to address social risks and promote well-being. This may involve reforming pension systems to ensure their long-term sustainability, expanding access to affordable healthcare, and providing social assistance to older adults in need.
- Combating ageism: Raising awareness about ageism and promoting intergenerational solidarity can help create more inclusive societies. This may involve public education campaigns to challenge age stereotypes, promoting intergenerational programs that bring older and younger people together, and enacting legislation to protect older adults from discrimination.
- Investing in long-term care: As the number of older adults with care needs increases, investing in long-term care services and support systems is essential. This may involve expanding the availability of home care services, developing community-based care options, and providing financial support for families caring for older relatives.
Furthermore, international cooperation is essential to address the global challenges of population ageing. Sharing best practices, coordinating policy responses, and providing mutual support can help countries learn from each other and develop effective strategies to mitigate the risks of ageing populations.
The urgency of addressing these issues cannot be overstated. Population ageing is a defining trend of the 21st century, and its consequences will be felt across all aspects of society. By taking proactive and comprehensive action, countries can create societies that support the well-being of all citizens, regardless of age, and ensure a prosperous and sustainable future for all.
