@mekkaokereke there's definitely a stronger gender balance in Scandinavia and it's spread to some places in Europe, but certainly not places like Italy, which has a dramatically low birth rate partially because women just won't (see also the 4b appropriation in USA, but Italy's objection is more individual than organised)
@mekkaokereke you can see just how low Italy's birth rate is here. Like Japan, the birth rate is well below the replacement level, so the population is shrinking leaving a shrinking younger population to look after a growing older population. I can see this happening in the USA too, but that's going to put a lot more pressure on an already fragile white male population, which is not going to help the numbers in the graphs you presented.
