Lovely factoids from the last half of the 19th Century in the US West.
Over 1,000 women per 100,000 died in childbirth. Most women had children between the ages of 14 and 28 years old, and as many as they could, often 6-8 per family.
Average life expectancy of males was 40 years, 42 for females.
Disease was rampant in the Old West: smallpox, polio, dysentery, whooping cough, measles, scarlet fever, tuberculosis, pneumonia, cholera, typhus, typhoid fever, and influenza. Infant mortality was often as high as 50%.
Your factoids from the last half of the 19th Century persisted with some change into the early 20th Century in the former Old West, in my paternal grandparents’ case in KS. My grandmother began having children at age 20 in 1902 and concluded at age 40, bearing 10 children, 9 living to adulthood. So her progeny mostly beat the infant mortality stats. Her husband died at age 51 of abdominal sepsis from a burst appendix. She died 8 years later at age 50 of cervical cancer.
You kinda answered this but the life span was heavily skewed by the 50% infant mortality rate. If you made it to early teens you had a good chance of living well into your 60’s. I used to think that 44 was it for a male but when I did a genealogy project on my family - which is very large on both sides I found literally 30 infants that didn’t make it a year and many males well into their late 60’s before passing. Of course the Civil War was horrendous and skewed two generations of lifespan statistics
