Ninety percent of the centenarians studied in the New England Centenarian Study were functionally independent the vast majority of their lives up until the average age of 92 years and 75% were the same at an average age of 95 years. [26] Similarly, a study of US supercentenarians (age 110 to 119 years) showed that, even at these advanced ages ...
Life expectancy in the U.S. was just 47.3 years old in 1900. It rose steadily for over a century until it peaked at 78.9 years in 2014 before declining in 2015, reaching 76.4 years in 2021. It ...
By 2030, 20% of Americans are projected to be 65 and older. [87] Both the overall population of the country and the average age are projected to increase over coming years.

By that time, it had become clear that the mainstay of retirement research, the Retirement History Study (RHS), conducted from 1969 to 1979, was no longer adequately ...
For example, a population's life expectancy at birth is the same as the average age at death for all people born in the same year (in the case of cohorts). Longevity studies may involve putative methods to extend life. Longevity has been a topic not only for the scientific community but also for writers of travel, science fiction, and utopian ...
