Life Expectancy Is Plateauing, Won't Reach 100, Researchers Say
Researchers report that without major medical breakthroughs, life expectancy increases have slowed due to past reductions in infant mortality and limited gains in older adult care.
- On August 27, 2025, researchers reported that average life expectancy is unlikely to surpass 100 years in the near future, and individuals born post-1939 are not expected to live to 100 on average.
- They traced this trend to past longevity gains driven mainly by rapid declines in infant death rates due to early 20th-century medical and quality-of-life improvements, which have since slowed considerably.
- Between 1900 and 1930, average life expectancy increased by approximately five and a half months with each successive generation, but from 1939 to 2000, the rate of improvement declined to about two and a half to three and a half months per generation.
- Lead researcher José Andrade from the Max Planck Institute predicted that individuals born in 1980 are unlikely to live to 100 years old on average, and no group examined in the research is expected to achieve this age milestone.
- Senior researcher Héctor Pifarré i Arolas said without major breakthroughs extending human life, future improvements will not match early 20th-century gains, affecting planning for retirement and savings.
