• China is one of the world’s most unaffordable places to raise a child, a Beijing think tank says.
  • The cost of raising a child compared to GDP per capita is 6.3 times in China, but 4.11 in the US, it said.
  • The cost of raising a child is sinking China’s already falling birth rate, the researchers said.

    Still increasing population, but the rate at which we are increasing has slowed.

    This statement suggests that we can’t do math and can’t accurately predict whats going to happen with population increases or decreases. We know how old a human being generally has to be to give birth, and we know how many humans we have of each cohort. Its pretty easy to see that what the population increases or decreases will occur when the younger cohorts come of age.

    The number we care about is “replacement rate”. A growing replacement rate is: 2.1. This means that each parent will replace themselves with a new child, and then 1 tenth of another. Practically this means 9 out of 10 of two parents have two children and the 10th of 10 parents will have 3 children.

    So we just have to look up the replacement rate for each country, and for it to grow from domestic population growth alone.

    Countries being discussed in trouble:

    • Russia = 1.42 source
    • China = 1.15 in 2021, is now approaching 1.0 source

    Country being discussed doing okay:

    So why is the USA okay while China and Russia are in a bad place if everyone is below 2.1? New births aren’t the only way to increase a country’s population. Immigration also works.

    • Russia = 0.626 per 1000 population source
    • China = negative 0.253 per 1000 population source
    • USA = 2.768 per 1000 population source

    So with immigration the USA is doing fine and dandy, Russia is barely holding on while marching its child bearing age men into the meat grinder of war, and China is having people not have babies all the while thousands of them are leaving the country at the same time.

      Just to note, immigration only works as long as there are source countries with high birth rates. Even those countries (many African ones) are seeing declines in their birthrate.

        How do you figure that? If a country is a horrible place to be, and even has a replacement rate below 2.1 there a can be emigration far greater from that country with the population going elsewhere. Present day Venezuela is a good example of this.

          I meant from a global perspective. A lot of people think falling birth rates in western countries are fine since they can sustain via immigration from countries with high birth rates. They generally don’t realise that the birthrate is falling globally, and then it’s just a matter of which country gets fucked first.

            If you’re talking from the perspective of the survival of humanity, sure. However that’s far enough out that much larger factors (like climate change related war and famine) are going to threaten human growth long before the global replacement rate is an issue.

              Oh yes, I fully agree. As I mentioned in my first comment the birthrate decline isn’t going to help us with any of the issues we’re currently facing, it’s just going to throw a bunch of new issues at us and most people don’t even realise that.

                I think the distinction between our two perspectives is you are looking globally which blurs the lines and “smooths out” the problem a bit until everyone is experiencing problems, where I’m focusing on nation states. Some of which will be hit much much harder or much faster than other nations. Just a guess on my part, but the difference in countries feeling this could be separated by 3 generations or more. Some are countries experiencing it right now while other countries great grandchildren will be the first to experience it.
