Will Tinder be blamed for the sudden decline in fertility rate? Is there any other plausible explanstion to South Korea’s sudden and dramatic drop in fertility rate to 0.8? No matter how bad the housing market is or the job market is, there has never in history been such a drop in population.

    Male hypergamy and polygyny has been practiced by many cultures historically. They had many problems, but low birth rates wasn’t among them. I don’t think dating apps are a sufficient causal explanation alone for low birth rates

    This explains the drop from 50s not the 2000s.

    perhaps religious and moral pressure not to excersize the choice available has decreased between 50s and 2000s

    Cell-phones. Noone’s having sex because they’d rather watch Tik-Tok; it’s got lower friction than going outside.

    Most of the drop occurred in the late 50s to mid 60s. Fertility in the US peaked at over 3.5 births per woman in the 50s before falling below 2 by the late 60s. It then stabilized for 40 years and even recovered to the low to mid 2s in the 90s and 2000s before falling post-2008 from 2.2 to 1.7.
