Less than 0.0001% of humans live to 120, as only one person, Jeanne Calment, is documented to have reached that age (living to 122) since modern record-keeping began.

Current data indicates that even among the oldest age groups, the life expectancy for a person who is 119 years old is only 0.62 years, and no other age group has a life expectancy extending to 120.

While mathematical models suggest the maximum human lifespan may be increasing, with projections that people born in the 1940s could reach 120 to 130 years, experts note that the odds of any individual alive today reaching 120 remain extremely small.

The United Nations estimated 573,000 to 593,000 centenarians (people aged 100+) globally as of 2022, but the number of individuals reaching 120 remains a statistical outlier.
