Infants once had a higher chance of dying than people aged 80

the gist

For most of human history, infancy was an extremely dangerous stage of life, and a newborn was more likely to die in its first year than an 80-year-old was to die in a given year. Historical records from many countries show very high infant mortality before modern sanitation, vaccines and healthcare spread. Over the last two centuries, infant deaths fell dramatically in most parts of the world, while life expectancy rose. The reversal is one of the clearest signs of how much human health has improved. The contrast shows how transformed the experience of childhood has been.

so what

It reframes progress: the long gains in life expectancy came largely from saving babies and children, not only from extending old age.

background

Infant mortality is the death of an infant before its first birthday. The occurrence of infant mortality in a population can be described by the infant mortality rate (IMR), which is the number of deaths of infants under one year of age per 1,000 live births. Similarly, the child mortality rate, also known as the under-five mortality rate, compares the death rate of children up to the age of five.
