Life expectancy

Abstract

Across the world, people are living longer. In 1900, the average life expectancy of a newborn was 32 years. By 2021 this had more than doubled to 71 years, caused by the large reduction in child mortality and an overall increase in life expectancy at all ages, resulting from advances in medicine, public health, and living standards. There are wide differences in life expectancy around the world, even within countries. Women tend to live longer than men, but this gap has changed over time. Life expectancy has surpassed predictions again and again. – AI-generated abstract.
