The Growing Centenarian Population
The number of people living to 100 or older in the United States has seen a substantial increase over the past several decades. Official figures from the U.S. Census Bureau's 'Centenarians: 2020' special report counted 80,139 Americans aged 100 and over in 2020, representing a 50% increase from 2010. This rapid growth rate signals a major demographic shift.
More recent estimates point to even higher numbers. For example, the Pew Research Center reported an estimated 101,000 Americans were 100 or older in 2024. Looking forward, demographers predict this number will continue to rise dramatically. According to U.S. Census Bureau projections cited by Pew Research Center, the centenarian population is expected to more than quadruple by 2054, reaching about 422,000. This trend underscores the evolving needs of an aging society.
Characteristics of the Centenarian Population
Studying the demographics of those who live to 100 and beyond provides valuable insights. One significant characteristic is the gender disparity, with females making up a substantial majority of centenarians. In 2020, females accounted for 78.8% of the total, and projections indicate they will likely remain the majority.
Geographic distribution also varies across the U.S. In 2020, Hawaii and Puerto Rico had a higher proportion of centenarians relative to their population, while states like Utah and Alaska had a lower proportion. Living arrangements differ by gender, with a higher percentage of female centenarians living in nursing homes compared to males in 2020.
Factors Contributing to Increased Longevity
Several factors contribute to the rising number of Americans over the age of 100, including improvements in public health, nutrition, medical technology, and lifestyle changes. Genetics also play a significant role in exceptional longevity.
- Healthcare Advancements: Effective treatments for chronic illnesses have increased lifespans.
- Lifestyle Changes: Emphasis on wellness, including diet and exercise, has improved overall health.
- Genetic Predisposition: Genetics contribute to the ability to reach exceptional ages.
- Socioeconomic Factors: Access to stable income, education, and healthcare can contribute to longer lives.
- Compression of Morbidity: This concept suggests centenarians often remain relatively healthy late in life.

Conclusion: A Look Towards the Future
The centenarian population is a small but rapidly expanding demographic group in the U.S. The number of Americans living beyond 100 has grown significantly and is projected to continue increasing, with the U.S. Census Bureau anticipating a more than fourfold increase over the next 30 years. This shift will place new demands on healthcare and social support systems. The demographic makeup of centenarians is also expected to become more diverse over time. Research into this unique population continues to offer valuable insights into exceptional longevity. {Link: Census.gov https://www.census.gov/newsroom/press-releases/2025/centenarian-population.html}
