> demographic expansion has been a side effect of technological development There was also a cultural side to it. Instead of being a linear relationships, it's more that technological development removed a population bottleneck and antiquated old family planning practices. Population growth is iirc highest in agricultural areas that experience significant increases in health care access and overall life expectancy. Instead of having to have 6-8+ children to ensure that 1-2 male heirs live to adulthood, suddenly you're faced with the burden of having to care and feed for every single child until they become self sufficient. This eventually drives the birth rate down to an economically sustainable level.
