Current U.S. and Global Statistics
The proportion of older people in society is a key indicator of demographic change. For the United States, recent data from the U.S. Census Bureau indicates that in 2024, the population aged 65 and older had risen to approximately 18%. This represents a significant increase compared to previous decades. Looking globally, the trend is even more pronounced. The United Nations reports that the worldwide population aged 65 or older is on track to more than double in a generation, projected to rise from 761 million in 2021 to 1.6 billion by 2050. In 2021, one in ten people globally were aged 65 or above, a figure that is projected to climb to one in six by 2050. This reflects a demographic transition toward longer lives and smaller families in many countries around the world.
The Impact of the Baby Boomer Generation
Much of the population aging trend in the U.S. is attributed to the aging of the large Baby Boomer generation, born between 1946 and 1964. The final members of this cohort will turn 65 by 2030, at which point the older adult population will comprise roughly one in five Americans. This large-scale demographic shift creates both opportunities and challenges for the economy and society at large. As this generation enters retirement, it increases the demand for senior-specific services, from healthcare and housing to recreational activities.
Future Projections for the Older Population
Demographic experts project that the aging trend will continue in the coming decades. In the U.S., the number of Americans aged 65 and older is expected to continue its rapid growth. By 2040, about one in five Americans will be 65 or older, and that number will continue to climb. Globally, the most significant growth in the older population is projected in Eastern and South-Eastern Asia and Central and Southern Asia. While Africa's older population percentage is currently low, it is also projected to grow rapidly over the next 30 years.
Social and Economic Implications
An aging population has far-reaching effects on society, impacting everything from economics to family life. The retirement of a large segment of the workforce can lead to a smaller pool of working-age people, which could put pressure on labor markets, potentially driving up costs and slowing business expansion. Additionally, the increased proportion of retirees affects the worker-to-beneficiary ratio for social programs like Social Security and Medicare, which may strain government budgets.
From a social standpoint, there are notable shifts in family dynamics, with younger generations often taking on increased caregiving roles for their aging parents or grandparents. This can involve providing financial and emotional support, as well as navigating complex end-of-life planning. On the other hand, many older adults are working longer, remaining in the workforce past traditional retirement age, which brings valuable experience and knowledge to employers.
Comparison: U.S. vs. Global Aging Trends
To better understand the scale and speed of this global shift, a comparison of key data points is helpful.
| Characteristic | United States (Approx. 2024) | Global (Approx. 2021/2022) |
|---|---|---|
| Percent 65+ | 18% | 10% |
| Driving Force | Baby Boomer generation aging | Global demographic transition; increased lifespan |
| Projected 65+ Pop. (by 2050) | 22.8% | 1.6 billion total (1 in 6 people) |
| Oldest Countries (examples) | Maine (23% in 2022) | Japan (28.2% in 2020) |
Healthcare Demands and Considerations
With an aging population comes an increased demand for healthcare services. Most older adults have at least one chronic health condition, and many have multiple. This includes an increased prevalence of heart disease, arthritis, diabetes, and neurodegenerative conditions like dementia. This necessitates greater resources for geriatric care and puts pressure on healthcare systems. Issues such as the shortage of healthcare professionals, particularly those with expertise in geriatrics, become more pronounced. Finding adequate long-term care solutions is also a growing concern, as many older adults prefer to age in place in their homes for as long as possible. Prevention is a critical part of addressing these healthcare demands, though it remains underfunded compared to treatment efforts. The average life expectancy at age 65 has also increased, meaning older adults are living more years, but not always in perfect health, thus increasing the duration of care needed.
Navigating the Future of an Aging World
Policymakers and communities worldwide are grappling with how to adapt to the reality of an aging population. This involves exploring new approaches to healthcare, retirement, and social support. From encouraging labor force participation among older adults to developing age-friendly technologies and communities, innovative solutions are required. Addressing the widespread economic disparities that affect older adults is also critical, as is ensuring income security for those on fixed incomes. Understanding the answer to "what percent of the population is above 65?" is more than just a statistical exercise; it is about comprehending a profound demographic shift that impacts everyone.

Conclusion
The rising percentage of the population over 65 is a defining demographic trend of our time, both nationally and globally. In the U.S., the aging Baby Boomer generation is pushing this figure upward, with projections pointing toward a continued increase. Globally, the number of older adults is set to double in the coming decades, reshaping societies in profound ways. These shifts require proactive planning to address the implications for healthcare, economic stability, and social support systems. By understanding the data and the factors at play, we can better prepare for the future of an aging world and foster a society that supports people of all ages.
