Current Oldest Human Alive
As of the latest public records, the oldest living person is Tomiko Itooka, a Japanese woman born on May 23, 1908, making her the world's oldest verified individual. Her age is officially recognized by Guinness World Records and gerontology research groups that track supercentenarians. The Gerontology Research Group and Guinness World Records maintain the authoritative global registry of the oldest humans, using documents such as birth certificates and government records to validate claims.
Guinness World Records updates its oldest-living-person title only after rigorous verification of identity and date of birth, and the current holder is Tomiko Itooka, who surpassed previous record holders such as Maria Branyas and Lucile Randon in recent years. The Gerontology Research Group independently tracks unvalidated and validated cases of extreme age, providing a parallel dataset that often precedes official Guinness recognition. These organizations rely on cross-checked civil registries and family testimonies to confirm that the individual is still alive and the claimed birth date is accurate.
Verified Longevity Records and Historical Context
The longest verified human lifespan belongs to Jeanne Calment of France, who lived to 122 years and 164 days, a record that has stood since her death in 1997 and is cited by Guinness World Records and longevity researchers. The Gerontology Research Group maintains a validated list of supercentenarians, individuals who have reached age 110 or older, and tracks how many are currently alive and their verified ages.
Japan has the highest number of verified supercentenarians in the world, a fact linked to its national health insurance system, diet, and social support structures that are studied by demographers and gerontologists. The United States, France, and Italy also have significant numbers of validated supercentenarians, and organizations such as the Gerontology Research Group and Guinness World Records publish tables showing country-level rankings and trends in extreme longevity.
Factors Influencing Extreme Longevity
Research points to a combination of genetics, lifestyle, and healthcare access as key factors in reaching extreme old age, with studies from institutions such as the New England Centenarian Study highlighting the role of specific gene variants linked to longevity. Diet, physical activity, social engagement, and avoidance of smoking and excessive alcohol are consistently associated with longer life spans in populations with high numbers of centenarians and supercentenarians.
Advances in medicine, public health, and nutrition have increased the number of people who survive into their 100s, and organizations such as the World Health Organization and national health agencies track these trends through global and country-level data. Financial planning for longevity, including pensions and healthcare costs, is a growing concern for governments and private sectors, as documented in reports from institutions such as the World Economic Forum and research centers focused on aging.
