e: over post limit
Equilbirium doesn't have to be current population level. maybe japan with 60m population and lower urban density to enable average house size increase from 1000 sqft to 2000 sqft + other interventions will get TFR closer to replacement @ 60M. Govs still going to have to pile on lots of carrots and sticks on top to make decisions swing towards 2 kid+ households. But it seems like most of Asia/Europe pop density + limited housing is one impediment to raising families.
Sustainable equilibrium is replacement TFR.
Even an all-time high increase in foreign residents of more than 10%, to 2.99 million, couldn’t halt a slide in the total population, which has declined for 14 years in a row to 122.42 million in 2022.
Japanese naturlization laws:
(Acquisition of nationality by birth) Article 2.
A child shall, in any of the following cases, be a Japanese national: (1) When, at the time of its birth, the father or the mother is a Japanese national; (2) When the father who died prior to the birth of the child was a Japanese national at the time of his death; (3) When both parents are unknown or have no nationality in a case where the child is born in Japan.
It's a funny place in this way. They seem to prefer extinction level population decline rather than accepting children of foreigners who were born there.
I know it's not the only country who doesn't do naturlization from birth, but seems short sighted considering. You think they could get past it at some stage, but no.
There are apparently millions of illegal immigrants working in Japan who don't gt any type of residency status.
