I’m confused about life expectancy. What is it exactly, the number of years you’re expected to live at birth?
What about countries which have higher child & infant mortality and therefore life expectancies of about 40 years. Does that mean a minority of people die young, but everyone else lives to be about 70-80?
What corrections for life expectancy are there when you subtract lives lost to infant and childhood mortality? Would that increase life expectancy in countries with an expectancy of 40 to about 70?
