What percentage of U.S. citizens are 65 and older? Understanding America's Aging Population

4 min read

According to the U.S. Census Bureau, the population of older adults continues to expand, reaching 18.0% in 2024. This reflects a steady demographic shift that makes the question, what percentage of U.S. citizens are 65 and older, increasingly relevant for healthcare and policy planning.

Quick Summary

The U.S. population aged 65 and older grew to 18.0% in 2024, a notable increase driven largely by the aging Baby Boomer generation and greater longevity. This demographic trend has significant implications for everything from healthcare to the workforce.

Key Points

  • Growing Demographic: In 2024, 18.0% of the U.S. population was aged 65 and older, a percentage that has been steadily increasing.

  • Baby Boomer Effect: The aging of the large Baby Boomer generation, born between 1946 and 1964, is the primary driver of this population shift.

  • Increased Longevity: Higher life expectancy due to medical advances and healthier lifestyles contributes to the growth of the older adult population.

  • Geographical Variation: The percentage of seniors varies significantly by state, with retirement destinations like Florida and Maine having higher concentrations.

  • Socioeconomic Challenges: This demographic shift impacts social programs, healthcare costs, the labor force, and increases the demand for senior care services.

  • Emphasis on Healthy Aging: Proactive strategies focusing on physical activity, nutrition, and mental engagement are crucial for supporting seniors' quality of life and independence.

A Growing Demographic: The Latest Figures

Official data from the U.S. Census Bureau provides the most accurate and up-to-date insight into the age distribution of the American population. According to the Vintage 2024 Population Estimates, the segment of the population aged 65 and older has reached a significant milestone. The U.S. population age 65 and older rose by 3.1% to 61.2 million, now representing 18.0% of the total population. This continues an ongoing trend of a steadily increasing older population relative to younger age groups, whose share of the population is declining. For perspective, the 2020 Census reported that 16.8% of the population was 65 and older, showing a marked increase over just a few years. The sheer number of older Americans continues to grow rapidly, presenting new challenges and opportunities for society.

The Factors Behind the Trend

This demographic shift is not accidental but the result of several long-term factors. The most prominent is the aging of the Baby Boomer generation, those born between 1946 and 1964. Having begun turning 65 in 2011, this large cohort has been swelling the ranks of the older population for over a decade. By 2030, all Baby Boomers will be 65 or older, at which point the growth rate of the senior population is projected to slow.

Increased Longevity and Lower Birth Rates

Another crucial factor is increased life expectancy. Medical advancements and improved public health have allowed Americans to live longer, healthier lives than in previous decades. Simultaneously, sustained lower birth rates have meant a smaller proportion of younger people entering the population, further increasing the relative size of the senior demographic. These two forces combine to create a top-heavy age pyramid, with the share of the population under 18 decreasing from 25.0% to 21.5% between 2004 and 2024.

Geographical Distribution of Older Americans

The aging of the U.S. population is not evenly distributed across the country. Certain states have a much higher percentage of older residents than others, often influenced by migration patterns for retirement. The U.S. Census Bureau tracks these variations, with data showing significant differences.

A Comparison of States' Older Population Percentages

State Older Population % (Latest Data Cited) Average U.S. % (2024)
Maine 23.0% (2022) 18.0%
Florida 22.0% (2022) 18.0%
Vermont 22.0% (2022) 18.0%
Utah 12.2% (2023) 18.0%

Retirement destinations like Florida and communities with lower out-migration rates for seniors tend to have higher proportions of older adults. Conversely, states with younger populations often have large universities or a higher proportion of young families. This geographical concentration of seniors impacts local economies, infrastructure, and the demand for age-specific services.

Socioeconomic Impacts and Challenges

The demographic shift toward an older population has profound socioeconomic implications. The rising number of seniors puts pressure on social programs like Medicare and Social Security, as fewer working-age adults support a growing number of retirees. Additionally, there is a surge in demand for senior care services, from assisted living facilities to in-home care. This creates both a challenge in staffing and a significant economic opportunity.

Navigating the Future of Healthcare and Senior Services

The healthcare system must adapt to this growing population. This includes addressing the higher prevalence of chronic diseases among older adults and the need for long-term care. The rise of family caregiving also highlights the emotional and financial strain on families, and the need for more support resources. Public policy, public health initiatives, and private industry are all grappling with how to best support the aging population with dignity and financial stability.

Promoting Healthy Aging in an Older Society

While the challenges are real, the focus on healthy aging is a powerful tool to improve quality of life for seniors and manage societal costs. Healthy aging is a proactive approach focusing on wellness, independence, and overall well-being.

Lifestyle Changes for Better Golden Years

  • Stay Physically Active: Regular, moderate physical activity, like walking, swimming, or yoga, is a cornerstone of healthy aging. It helps maintain strength, flexibility, and balance, reducing the risk of falls.
  • Prioritize Nutrition: A balanced diet rich in fruits, vegetables, and lean protein supports brain function and overall health. The MIND and DASH diets are often recommended.
  • Engage Socially: Combating loneliness and social isolation is critical for mental and physical health. Hobbies, volunteering, or connecting with family and friends can boost mood and well-being.
  • Keep Mentally Stimulated: Learning a new skill, reading, or playing puzzles can help sharpen the mind and maintain cognitive function.
  • Manage Health Proactively: Regular health screenings and managing chronic conditions effectively are essential for maintaining independence.

Conclusion

The increasing percentage of U.S. citizens aged 65 and older is a defining demographic trend of our time. At 18.0% of the population in 2024, seniors are a growing and influential segment of society. This shift is reshaping healthcare, policy, and community structures. By understanding the forces driving this change and focusing on strategies for healthy aging, individuals and communities can better adapt to and thrive in this new era.
