Historical Life Expectancy

Cluster focuses on debunking misconceptions about past life expectancies being low due to infant and child mortality skewing averages, noting that adults who survived childhood often lived into their 60s or older, with references to data on age-specific expectancies.

You are off by a factor of 2. If you exclude deaths in early childhood people regularly made it to their 60s

I guess you are talking about life expectancy being way lower back in the day. Those numbers are massively skewed by infant mortality and so many other things (infections, complications during child birth, ...) that are nowadays easily sorted out by antibiotics and other means.

because it is average lfe expectancy, just as infant mortality lowered it before, mass death of old people also lowers it

are you controlling for global life expectancy?

piuantiderp May 1, 2024 View on HN

Yes but has life expectancy of the people "who would not have died in child mortality" improved? Seems like a dishonest use of averages

https://ourworldindata.org/its-not-just-about-child-mortalit... has life expectancies for age ranges from 1841 and shows a huge difference for a 5 year old. If conditions get worse with age then the average going from 55 to 82 (from age 5) could hide a lot of data about these disorders.

Life expectancy might not be what you think it is. Life expectancy is average expected lifetime at a particular age. We usually talk about life expectancy at birth. If a population has a high infant mortality rate, then life expectancy at birth may be 40, but life expectancy at 10 years of age might be 70. I can't name a source off hand, but I believe I've read that infant mortality is a large factor in low life expectancies. In other words, we may not have significantly increased li

Life expectancy back then was quite different than it was today.

JoeAltmaier Sep 15, 2023 View on HN

For an adult, life expectancy then was 55 or better!See, infant mortality was shit back then which accounted for a big bias in that lifetime '37'. If you survived childhood then you did pretty well.https://ourworldindata.org/its-not-just-about-child-mortalit...

Not sure exactly what you mean but you can have lower average life expectancy and still see lots of people reaching old age (60-80).Longer average contemporary lifespan in the west has a lot to do with infant/child mortality.
