I'm not an expert, but I see some major flaws in this post doesn't make sense to me. Please feel free to correct me if I've misunderstood any concept.

>At 22,870 inhabitants per km², Macau is the densest jurisdiction in the world, denser than Singapore which itself suffers ultra-low fertility. Virtually everyone in Macau lives in an apartment tower. Studies (see below for a thread reviewing the literature) find that density is linked to low fertility, so perhaps we shouldn't be surprised if the densest place on Earth also has the lowest birthrates.

Exteremly high density will obviously lead to lower fertility since most residents barely have space for themselves. This is not what most people are talking about when asking for higher density housing. Looking at extreme cases does not mean moderate density will have the same outlook.

> Tokyo, Japan, provides a great natural experiment. What happens when you build urban high-rise towers in abundance? We once thought of Tokyo as expensive, but that is no longer true. Apartment towers have been added to the Tokyo skyline at a rapid clip, making it eminently affordable for young people.

This statement ignores a lot of the socio-economic problems in Japan. Problems such as decades economic stagnation, the extreme work culture, younger people being straddled with the burden of caring for older generations. These and many other problems combined are the reason for low fertility.

> Australia, where the pricey suburbs are much more fertile

I wonder who can afford to move to expensive suburbs ? Oh right its wealthy people. I wonder who can afford to have enough free time to take care of children and also afford expensive child care services ? Oh right its wealthy people.

The problem isn't density, the problem is that people in child bearing age cannot afford to have children.

> New Zealand may not show what people think it does

Similar problems to Australia, people in child bearing age cannot afford to have children.

> After the war, Korea saw a housing crisis and resolved to build huge apartment towers as fast as possible. China too has gone the path of ultra-dense apartment blocks. Now both countries are stuck in an ultra-low fertility regime. They desperately try to pivot to higher birth rates, but their built housing stock dooms them. Young people in both countries are drawn to low fertility city life, and the depopulation conveyor belt runs hot.

These countries have problems similar to Japan, extreme work culture, lack of free time, lack of affordable housing, younger people being constantly burnt out. Mostly wealthy people with free time are having children.
