People do not like have kids in a high population density environment. Humans have a trigger that suppresses fertility when there are too many people around.

- dennisgorelik 9y agoCities have much lower fertility rates than suburban and rural areal. https://www.ncbi.nlm.nih.gov/pubmed/12288643 https://www.ncbi.nlm.nih.gov/pubmed/12288643
- Domenic_S 9y agoThat’s a leap. Cities have lower both rates, so humans must have a trigger that turns down fertility?
- lukealization 9y agoThe OP nor the study made no indication that the two were related — merely that they correlate.
- pavel_lishin 9y agoOP very explicitly claimed there's a trigger: > Humans have a trigger that suppresses fertility when there are too many people around
- in_cahoots 9y agoThere are vast differences between rural and urban populations, especially in China. The fact that urban households have fewer children in no way implies that density leads to reduced fertility.

- grondilu 9y agoThis is plausible but definitely requires references. I would not be surprised if it were something that can be seen in other mammalian species.
- wbl 9y agoThere are strong evobio reasons to be extremely skeptical of that comment.
