I believe you are miss reading the correlation, having more children isn’t making people poorer, it’s part of a more complicated cycle of poverty that involves lower levels of education and attainment which leads to poorer income and poorer fertility planning. The strongest correlation is with female education levels.





Fertility rates have been falling across the world since the baby boom that followed WW2 in line with greater female education and labour market participation. Also people from poorer and less educated background in wealthy countries are the people who have the highest fertility rates.
