What we can basically dub the "idiocracy hypothesis" is becoming less true than it was in the past, not more true. Take a look at the second section for 1995-2010 changes: https://www.theatlantic.com/sexes/archive/2013/02/lets-not-panic-over-women-with-more-education-having-fewer-kids/273070/ https://www.theatlantic.com/sexes/archive/2013/02/lets-not-p... Yes, the less educated still have more children than the more educated, but that gap is getting smaller. ---------- In more current data: Teenage pregnancies are down by 55% since 2007, which is an enormous public health success that no one seems to have noticed. And while I can't find more recent data by educational attainment, there does appear to be racial data, which given the enormous differences in average educational attainment between racial groups, are something you can make inferences from. The groups which are statistically lower educational attainment have seen 2-6x larger drops in fertility than the groups which are statistically higher educational attainment. https://www.nytimes.com/2018/05/17/us/fertility-rate-decline-united-states.html https://www.nytimes.com/2018/05/17/us/fertility-rate-decline...
