A Defining Global Trend: The Rise of the 60+ Population
In 2024, nearly 13% of the world's population was aged 60 years or older. This signifies a monumental demographic shift, with the number of older persons having doubled since the early 2000s. This rapid aging of the global population is driven by two primary factors: increased life expectancy and declining fertility rates. People are living longer, healthier lives than ever before, while birth rates in many parts of the world have slowed. For the first time in history, in 2020, the number of people aged 60 and over outnumbered children under the age of five. This trend is not just a footnote in demographic studies; it is a force that is actively reshaping economies, healthcare systems, social structures, and family dynamics across the globe.
Future Projections: A Planet Reshaped by 2050
The pace of population aging is set to accelerate dramatically. According to projections from the United Nations and the World Health Organization, the proportion of the world's population over 60 will nearly double between 2015 and 2050, rising from 12% to 22%. By the middle of this century, the number of people aged 60 and over is expected to reach 2.1 billion. Even more strikingly, the number of individuals aged 80 or older is projected to triple, reaching 426 million by 2050. This isn't a phenomenon restricted to wealthy nations; by 2050, it's estimated that 80% of all older people will live in what are currently low- and middle-income countries, which are experiencing the fastest demographic changes.
Regional Differences in the Aging Wave
While population aging is a global phenomenon, its pace and intensity vary significantly by region. Continents like Europe and North America have been aging for decades, whereas regions like Africa are much younger demographically.
- Europe: In 2024, about 25% of the population in Europe is already aged 60 or over. This is projected to rise to 35% by 2050. Countries like Japan lead the world, with over 30% of its population already over 60.
- Asia & Latin America: These regions are expected to see the steepest increases in their older populations. By 2050, their share of people aged 65 and over will more than double, surpassing the levels seen in Europe today.
- Africa: As the world's youngest region, Africa's population aged 60 or over is projected to grow from 5% in 2017 to around 9% by 2050. While this percentage is lower, the absolute growth in numbers will be substantial.
Comparing Aging Metrics Across Development Levels
The challenges and opportunities presented by aging differ between developed and developing nations.
| Metric | Developed Nations | Developing Nations |
|---|---|---|
| Pace of Aging | More gradual, over many decades | Extremely rapid, often within a single generation |
| Healthcare Systems | More established, but strained by chronic diseases | Often under-resourced and needing rapid adaptation |
| Social Support | Mature pension and social security systems | Informal family support is common; formal systems are developing |
| Economic Impact | Focus on the "silver economy" and retaining older workers | Challenges of providing for seniors while still developing |
The Societal and Economic Impact
The aging of the world's population has profound implications for every facet of society.
- Economic Growth: A shrinking working-age population relative to the number of retirees can slow GDP growth. This puts pressure on public budgets, with fewer workers supporting a growing number of dependents through taxes.
- Healthcare Demand: Older populations require different healthcare services, with a greater focus on managing chronic conditions like heart disease, diabetes, and dementia. This necessitates a shift in healthcare infrastructure and workforce training.
- Labor Markets: Many countries face potential labor shortages. This creates opportunities for older workers to remain in the workforce longer and drives innovation in automation and productivity.
- The Silver Economy: As the population of older adults grows, so does their economic clout. This creates a burgeoning market for goods and services tailored to their needs, from accessible housing and tourism to specialized technology and financial products.

Conclusion: Navigating the New Demographics
Understanding what percent of the world's population is over 60 is more than a statistical exercise; it's a critical tool for navigating our shared future. The shift towards an older global population presents significant challenges to our established social and economic models. However, it also offers opportunities. By promoting healthy aging, fostering age-friendly environments, and adapting our systems to this new reality, we can build societies that value and leverage the contributions of people of all ages, ensuring a more prosperous and equitable world for generations to come.
