Total Numbers vs. Per Capita
When asking what state has the most 100 year olds, the answer can be interpreted in two ways: the total number of centenarians or the proportion of centenarians relative to the total state population. Understanding this distinction is key to grasping the full picture of American longevity trends.
The States with the Highest Total Count
Highly populous states inevitably have the largest total counts of centenarians, even if their percentage per capita is relatively low. For instance, based on 2022 data, California, Florida, and New York were home to the greatest number of people over 100. This demographic reality is a simple reflection of population size and doesn't necessarily indicate a superior environment for aging well.
The Per Capita Champions
Conversely, examining centenarian numbers per capita reveals which states have the highest concentration of long-lived residents. For many years, Hawaii has led this ranking, with its 0.24% of the population over 100 in 2022 making it the highest in the nation. Other states that have often ranked highly in this category include Washington D.C. and Connecticut. These states offer valuable insights into the social and environmental factors that support extreme longevity.
Why Longevity Varies by State
The distribution of centenarians is not random. Several key factors contribute to higher rates of longevity in certain areas:
- Genetics vs. Lifestyle: While genetics play a role in longevity, experts estimate that lifestyle and environmental factors account for up to 80% of how long people live. This means a person's chances of reaching 100 are influenced more by their daily habits and surroundings than by heredity alone.
- Community and Social Engagement: States with a strong sense of community and social cohesion, like Hawaii and Utah, often report higher rates of well-being among seniors. Social engagement is a powerful antidote to isolation and contributes significantly to both mental and physical health in later life.
- Environmental Factors: Access to clean air and natural environments can play a part. Some long-lived populations, such as those in the "Blue Zones," benefit from geographical locations that encourage physical activity and connection with nature. Loma Linda, California, a recognized Blue Zone, contributes to California's longevity metrics.
- Access to Healthcare: The quality, cost, and accessibility of healthcare services for older adults vary significantly by state. States like Minnesota and Massachusetts are often praised for their comprehensive senior healthcare programs and robust medical facilities. Preventive care is also a major factor, with states like Utah pioneering models that emphasize proactive health management.
- Diet and Physical Activity: The lifestyle habits of residents, including diet and physical activity levels, correlate with longevity. For example, Hawaii's healthy island lifestyle and focus on physical activity, alongside Utah's low rates of risky behaviors like smoking, contribute to their strong health outcomes for seniors.
Comparison of Centenarian Prevalence (2020 Data)
| Rank | State or Territory | Centenarian Prevalence (Per 10,000) | Factors Contributing to Longevity |
|---|---|---|---|
| 1 | Hawaii | 4.1 | High life expectancy, healthy lifestyle, strong social ties |
| 2 | Connecticut | 3.5 | Excellent healthcare access and quality, strong senior life expectancy |
| 3 | Puerto Rico | 3.5 | Unique lifestyle factors, strong community bonds |
| 4 | Rhode Island | 3.4 | High physician availability, decent healthcare costs |
| 5 | South Dakota | 3.4 | Lower population density, potentially lower stress factors |
Note: Data from 2020 and 2022 reflect ongoing demographic changes, and state rankings can fluctuate over time.
Demographics of Longevity
Beyond location, the demographics of centenarians reveal other notable trends. For example, women consistently outnumber men among the centenarian population. In 2022, 78% of centenarians were women, a disparity that is projected to narrow slightly over the next several decades. The racial and ethnic composition of the centenarian population is also shifting. While the majority of centenarians today are white, projections indicate a growing diversity among future generations of people living past 100. This shift reflects broader demographic changes across the country and the expansion of longevity across different ethnic and socioeconomic groups.
The Path to 100: Insights from Centenarians
Making it to 100 isn't just about luck. Centenarians and longevity researchers often point to a combination of healthy habits and a positive mindset. The keys include maintaining a healthy diet, staying physically and mentally active, and nurturing strong social connections. These are the core principles behind the world's most successful long-lived populations, including those in recognized "Blue Zones". As the centenarian population continues to grow, so too will our collective understanding of what it takes to live a long, healthy, and fulfilling life.

Conclusion
Ultimately, the question of what state has the most 100 year olds offers a valuable lens through which to view longevity in America. While populous states like California lead in raw numbers, smaller states like Hawaii offer a glimpse into the ideal conditions for a person to reach extreme old age. The ongoing growth of the centenarian population underscores the increasing importance of embracing healthy lifestyle choices, accessible healthcare, and strong social ties to promote longer, healthier lives for everyone.
