What is a Supercentenarian?
An individual who reaches or surpasses the age of 110 is known as a supercentenarian. This distinguishes them from centenarians, who have reached 100 years of age. While the number of centenarians has been on the rise globally due to improvements in health and living conditions, the number of supercentenarians remains remarkably small and relatively constant. Experts estimate there are only a few hundred supercentenarians worldwide at any given time. This is because the rate of mortality after age 110 increases dramatically, making each additional year a profound accomplishment.
The study of supercentenarians is a specialized field within gerontology, as these individuals defy the typical aging trajectory. Research shows they often live a life free of major age-related diseases until very late, experiencing what scientists call a "compression of morbidity". This means they remain relatively healthy and functional until a very short period before death, in stark contrast to the longer periods of declining health and illness experienced by many older adults.
The World's Oldest Verified People
The most famous and longest-lived person with a validated age was Jeanne Calment of France, who passed away in 1997 at the age of 122 years and 164 days. Her longevity has been extensively documented and verified, though some disputed theories have emerged in recent years. While her record remains the benchmark, many others have lived past 110 and even 115. These documented cases are crucial for providing data points for longevity research.
Key characteristics of these individuals often include:
- Exceptional genetics, with a family history of longevity.
- Low prevalence of common age-related diseases until very late in life.
- Resilience, allowing them to withstand significant life events and stress.
- Maintenance of cognitive function, with some becoming "super-agers" who retain the memory of much younger individuals.
Notable Supercentenarian Studies
Several research initiatives focus specifically on supercentenarians to unlock the secrets of their remarkable longevity. One prominent example is the New England Centenarian Study, which examines genetic markers, environmental factors, and lifestyle choices of extremely old individuals and their families. Findings from these studies suggest a strong genetic component to living past 110, but also highlight the importance of healthy behaviors.
For instance, the study compared different age groups of centenarians and found that supercentenarians had a significantly lower percentage of years spent with age-related diseases. This indicates that reaching 110 is not just about extending life but also about delaying the onset of illness. Researchers look at genetic variants that may confer protection against common age-related disorders like heart disease, diabetes, and Alzheimer's.
How Do Supercentenarians Differ from Centenarians?
| Characteristic | Centenarian (100+) | Supercentenarian (110+) |
|---|---|---|
| Rarity | Becoming more common; tens of thousands in the U.S. alone. | Extremely rare; a few hundred worldwide. |
| Longevity Factor | A combination of genetics, lifestyle, and environment. | Stronger genetic predisposition is a key distinguishing factor. |
| Health Profile | May experience age-related diseases later in life compared to average lifespans. | Often experience a significant "compression of morbidity," remaining healthy until the very end. |
| Gender Skew | Predominantly female, though less so than supercentenarians. | Very heavily skewed toward females (around 90%). |
| Genetics | Some family history of longevity often present. | Stronger familial longevity history is typically observed. |
Factors Contributing to Extreme Longevity
Genetics: The Protective Shield
For supercentenarians, genetics play a more dominant role than for centenarians. Studies suggest that certain genetic variants provide a powerful protective effect against age-related diseases. Some supercentenarians carry genes that help repair DNA more effectively or that reduce the risk of cardiovascular disease and dementia. This genetic luck is a major reason why many supercentenarians maintain exceptional health and cognitive function into their final years. Researchers continue to map the genomes of these individuals to pinpoint these critical variants.
Lifestyle: The Supporting Pillars
While genetics can provide a strong foundation, lifestyle choices act as reinforcing pillars for longevity. Studies of supercentenarians and other long-lived individuals reveal common behavioral patterns:
- Maintain a sense of purpose: Many supercentenarians report having a strong sense of purpose that keeps them engaged with life.
- Active social connections: Strong social networks and family ties are consistently observed in long-lived populations, combating loneliness and social isolation.
- Healthy diet: While not always strictly followed (Jeanne Calment famously enjoyed port wine and chocolate), many adhere to a diet rich in fruits and vegetables.
- Physical activity: Supercentenarians often remain physically active, even with low-impact activities like walking or cycling, well into their later years.
- Resilience and stress management: Many share a common trait of handling stress well and maintaining a positive, non-anxious temperament.
Environment and Luck
Environmental factors also play a role, from access to quality healthcare to pollution levels. Furthermore, a dose of pure luck is often a key ingredient, as avoiding major accidents or sudden illnesses is crucial for reaching such an advanced age. The intersection of genetic fortune, healthy habits, and environmental luck is what allows a select few to join the ranks of supercentenarians.
What Can We Learn from Supercentenarians?
The existence and study of supercentenarians offer a hopeful message: that extreme longevity is not only possible but can also be accompanied by a high quality of life. The research shows that cognitive decline is not an inevitable consequence of aging for everyone. Instead, it is possible for some to maintain sharp mental faculties and physical independence far longer than the average person. By understanding the protective factors at play, researchers hope to develop new interventions that can help a broader population achieve a healthier and longer life, pushing the boundaries of the human healthspan.
For those interested in exploring the scientific basis of extreme longevity further, an excellent resource is the work of the Gerontology Research Group, which tracks and validates supercentenarian ages worldwide. This body of work provides the empirical data needed to understand this rare demographic phenomenon, offering insights that may one day benefit everyone.

Conclusion
In summary, yes, many people have lived to be 110 years old and even older, forming an exclusive group known as supercentenarians. Their existence proves that exceptional longevity, often accompanied by remarkable health, is a verifiable phenomenon. While genetics appear to play a powerful role in pushing past the 110-year mark, lifestyle factors and a dash of luck remain important contributors. The ongoing study of these individuals continues to push the frontiers of what we know about human aging, promising a future where a longer, healthier life might be within reach for many more.
