Yes, a few resilient individuals from 1920 still exist
While incredibly rare, it is an established fact that some individuals born in 1920 are still alive today. As of 2025, anyone born in 1920 would be celebrating their 105th birthday, placing them firmly in the category of a "semi-supercentenarian". This generation has witnessed two world wars, the Great Depression, the Space Race, and the dawn of the digital age.
Their survival into their second century is a remarkable feat, given the average life expectancy at the time of their birth. While it is challenging to obtain an exact count of every living individual, organizations that track longevity and demographics confirm their existence. A person who was born before or in the 1920s and lives to be 110 or older becomes a supercentenarian, and the longevity database LongeviQuest and Guinness World Records regularly confirm these exceptional individuals.
The Supercentenarian Phenomenon
- What is a Supercentenarian? A supercentenarian is someone who has lived to or past their 110th birthday. The number of supercentenarians is far smaller than the number of centenarians (100+), and they are often tracked by specialized research groups like the Gerontology Research Group.
 - Genetic Resilience: Studies suggest that supercentenarians have exceptional genetic traits that protect them from major age-related diseases until very late in life. They are essentially models of 'aging well'.
 - Sex Differences: Statistically, women have a much higher chance of reaching these exceptional ages. Approximately 90% of supercentenarians are female. Researchers believe this may be due to genetic advantages related to the X chromosome and potentially other biological factors.
 
Factors that contribute to exceptional longevity
The long lives of those born in 1920 and before are influenced by a complex interplay of several factors, which have been studied extensively by gerontologists.
- Genetics: A strong genetic predisposition for a long life runs in the families of many supercentenarians. Having family members who lived past 100 significantly increases an individual's chances of doing the same. Genetic factors can influence cellular functions like DNA repair and protection against damage from free radicals.
 - Lifestyle: Many centenarians attribute their longevity to disciplined and often simple lifestyles. Healthy diet, physical activity, and avoiding vices like smoking are commonly cited habits. Some also credit their longevity to a strong sense of purpose and low-stress living.
 - Environment: A person's environment plays a role, with some studies focusing on communities like those in Okinawa, Japan, and Sardinia, Italy, where traditional lifestyles and social structures seem to support longer lives. These regions are sometimes referred to as 'Blue Zones'.
 - Luck: While genetics and lifestyle are important, a certain amount of luck is undeniable. Avoiding life-threatening illnesses, accidents, and other random events is a necessary component of reaching such an advanced age.
 
Genetics vs. Lifestyle: A comparison for longevity
| Feature | Genetics | Lifestyle | 
|---|---|---|
| Primary Role | Provides a strong biological foundation for delaying or escaping age-related diseases. | Modifies health outcomes and can either support or hinder the genetic predisposition for longevity. | 
| Family Link | Often runs in families with multiple centenarians or supercentenarians. | Habits, diet, and physical activity levels are often learned or shared within family and community structures. | 
| Effect on Disease | Can provide resilience against certain diseases like cancer and heart disease. | A healthy lifestyle can help manage, delay, or prevent chronic conditions that shorten lifespan. | 
| The 'Escapee' Factor | Some centenarians have no clinically demonstrable disease at 100, suggesting genetics may play a larger role for them. | For others, lifestyle choices may be the key factor that helped them 'delay' the onset of age-related disease until after age 80. | 
The legacy of the 1920s generation
The 1920s generation is a testament to human resilience and the remarkable potential for a long life. For those who remain, their continued existence serves as a living bridge to an era that is now a century old. Their stories, often preserved by family members or documented by researchers, provide invaluable insights into the factors that contribute to exceptional longevity.
As the number of centenarians continues to increase globally, the lessons from the 1920s cohort become even more significant. They remind us that while advancements in medicine and technology play a vital role, factors like diet, social connections, and a positive mental attitude are also critical components of healthy aging.

In conclusion, while the number is small, there are definitely people alive today from 1920. Their existence is a powerful reminder that the human lifespan, while having natural limits, can sometimes exceed expectations, offering hope and inspiration to generations that follow.
