People keep saying high child death rates mean people have more children. But i have yet to find any proofs or research paper for this. What I really find is that as people's expectations of better living go up (not living expenses per se), then people have less children.
At first I disagreed, but after reconsidering I think absence of other evidence the increased child death rate and child birth rate are coincidental. I haven't seen data actually supporting the evidence that more children were born because more children died. I think it's plausible that the increased rights and health of people within our society both lead to decreases in child births and child deaths, but I've seen nothing to suggest that the death rate is causal to the birth rate.
Interestingly enough in Korea the mortality rate in 1955 was the same as in 2005. It increased in the 60s, peaked in the 80s, and has been declining again since the 90s
