Not really, because the population growth rate also includes adults dying later.
If someone dies at 75 instead of 80, their mother isn't going to consider giving birth another time to maintain the family size, but that person still gets counted in the total population size for five extra years.
I'm wondering how we could separate out these two situations.
Sure, but how do you separate out the change in life expectancy metric for people who do survive childhood from the ones who don't?
Basically the stat I'm looking for is "number of children per family that survive to adulthood," because I want to compare the change in that to the change in birth rate.
>The total fertility rate in a specific year is defined as the total number of children that would be born to each woman if she were to live to the end of her child-bearing years and give birth to children in alignment with the prevailing age-specific fertility rates. It is calculated by totalling the age-specific fertility rates as defined over five-year intervals. Assuming no net migration and unchanged mortality, a total fertility rate of 2.1 children per woman ensures a broadly stable population. Together with mortality and migration, fertility is an element of population growth, reflecting both the causes and effects of economic and social developments. The reasons for the dramatic decline in birth rates during the past few decades include postponed family formation and child-bearing and a decrease in desired family sizes. This indicator is measured in children per woman.
That's still not quite what I'm looking for. I want to compare that stat to the total number of children the average woman raises to adulthood, to understand better how an improved survival rate affects the number of children a woman gives birth to.
I'm looking for the term itself because I want to look up existing research on the subject, but can't figure out what to search for because I don't know what that stat would be called.
