The global population aged 60 and older exceeds 1.2 billion, making up 15% of the world’s total population. This number has doubled since the year 2000 and is expected to reach 2 billion in 2050.
This trend is not merely about an increasing number of people reaching old age; it reflects entire generations enjoying longer, healthier, and more active lives than ever before. The effects of this shift will resonate throughout societies, economies, and industries.
Why Is the Global 60 plus Population Growing So Rapidly?
The factors contributing to this demographic change are deeply embedded in medical advancements, economic growth, and lifestyle shifts that have occurred over the last century.
Increased Life Expectancy
In 1950, global life expectancy was approximately 46 years.
By 2000, it had risen to 67 years.
In 2025, it is projected to be over 73 years on average, with many developed countries exceeding 80 years.
This increase is due to improved medical care, better nutrition, reduced infant mortality, and advancements in managing chronic diseases. Conditions that were once life-threatening, such as cardiovascular diseases and cancer, can now be effectively managed for years, enabling people to live longer and healthier lives.
The Baby Boomer Effect
The baby boomers, now aged 60 to nearly 80, are the largest aging cohort in history.
Unlike previous generations, they have had access to better healthcare, education, and financial resources, enabling them to age more successfully. As they retire, they are not just adding to the 60 plus population—they are redefining aging, with new expectations for lifestyle, work, and healthcare.
Declining Birth Rates
While the older population is growing, birth rates are declining worldwide.
In 1960, the global fertility rate was about 5 children per woman.
Today, it is below 2.5 children per woman and far lower in developed nations.
This means that fewer young people are entering the workforce, while the proportion of older adults continues to rise—creating challenges for economic growth and pension systems worldwide.
What This Means for the Future
This demographic shift is not temporary—it is a permanent restructuring of society.
- The workforce will need to adapt to longer careers and multi-stage retirements.
- Healthcare systems must prepare for a greater demand for longevity-focused treatments.
- Businesses must recognize that older adults are not a burden but an economic powerhouse.
Understanding the forces behind this transformation is the first step in preparing for a world where people live longer, healthier, and more productive lives.
