Prof. Gary Becker (Nobel in economics) has linked the economics of fertility to economic growth since decades ago. His papers describe low fertility rates in many developed countries in the present pretty well. Here's a review article of his work: https://docs.iza.org/dp8610.pdf https://docs.iza.org/dp8610.pdf From the article: "Becker, Murphy, and Tamura show that the economy exhibits two steady states, one in which income per capita stagnates and fertility is high, and one in which there is sustained growth in income per capita and fertility is low. Thus, the model provides a joint explanation for the demographic and economic differences between pre-industrial, Malthusian economies (characterized by stagnation, a low return to human capital, and high birth rates), and growing, industrial economies with low population growth."
