Jul 1, 2021 · July 1, 2021. Summary: Extreme longevity will continue to rise over the 21st Century. Researchers estimate a lifespan of between 125 to 130 years will be possible. Source: University of Washington. The number of people who live past the age of 100 has been on the rise for decades, up to nearly half a million people worldwide.
In this review, we summarize and critically evaluate the major empirical, conceptual, and theoretical directions that social scientific studies of aging families have taken during the first decade of the 21st century.

Scientists are actively debating whether there is a fixed limit to the human life span. Some biologists think the data shows that aging is not a disease that can be treated, but instead an inevitable process that cannot be fully stopped, whether through medical breakthroughs or other means. Some demographershave argued that there is a natural limit...
Data on “supercentenarians,” or those who reach age 110, are limited and often of poor quality. There is the problem of “age-attainment bias”, or the tendency of very old individuals to misstate or exaggerate their age. For this reason, we’ve used only data from the International Database on Longevity, a collection of rigorously verified death reco...
Yearly mortality rates generally increase as people age. For example, individuals are more likely to die at age 80 than age 20. But this changes for those who make it to 110 years old. The best available data suggests that mortality rates for these “supercentenarians,” while high, do not increaseas they continue to age. In a sense, this means that ...
Predicting the extremes of humanity is a challenging task filled with unknowns. Just as it’s conceivable that a medical breakthrough could let humans live indefinitely, every individual to reach age 123 could simply die the next day. Instead, our study has taken a statistical, data-driven approach focused on what will be observed this century rathe...
That pattern led us to the second component of our study: projecting how many people will reach age 110 during the 21st century, which ends in the year 2100. Using population forecasting methods developed by our research group that are used by the United Nations, we found that large mid-20th-century population growth will likely lead to an ...
If we accept that life expectancy is a good measure of human development, the latest data are revealing about capitalist societies in the 21 st century. Life expectancy fell in the US in 2021 to its lowest since 1996, the second year of a historic retreat, mainly due to Covid-19 deaths.
