    That’s still not a graph of Japan.

    More importantly, you’re not looking at the derivative, that is, the growth rate:

    The growth has very much peaked, the last large countries are currently undergoing demographic transition (from having many kids, few survive, over having many kids, many survive (growth spike), to hawing few kids, of which pretty much all survive), e.g. Nigeria will be done by 2100. And societal collapse because people either can’t do anything but care for the elderly, or social cohesion is failing because the elderly aren’t cared for, does not depend on absolute numbers, it depends on the raw growth rate, because young people from 1900 aren’t going to care for the elderly in 2100. And the growth rate it depends on is the local one how many Nigerians do you think fancy caring for Chinese elderly.

    Oh and those projections above are with a moderate estimation of future fertility, that is, when the average country turns out like France. Not if the average country turns out like Japan or Korea.


    Also, just to make this clear: There’s nothing wrong with the population shrinking again. Or growing, the earth is far from its carrying capacity if we’re doing it right. The trouble is shrinking too quickly, or for that matter growing too quickly. We should pine for two kids per woman, ±0.5, thereabouts: Don’t veer too far off replacement levels. And all that can be done by proper social policy, parental leave, good schools, work/life/family balance, sex ed, etc.

      Yeah, i agree. Decline should be at an acceptable rate. Just that i think an acceptable rate for me is 0.66 children/woman. That would lead to an annual decline in birth rate of 3.6% (formula is: 1-(0.66÷2)^(1÷30)) assuming women give birth at 30 y/o.

      Just to contrast this: The US’ population (excluding Native Americans) grew steadily by approximately 3% annually from 1680 till 1880. Source:

        I don’t think citing the US supports your case. You’re talking about a country where the only time everyone is on one page, is interested in the same thing, a moment of cohesion, is the ads during superbowl. American culture may technically exist but it has close to zero depth. Regional identities are deeper, largely because immigrants clustered together, one source nation here, another one there.

        It’s also not really comparable because much of that increase was due to immigration, often whole families, also I think you meant more like 30%, not 3%. Niger has a growth rate of 3.66, a median age of about 15. Fifteen. Half are younger, half older than that. Politically, it’s a complete shitshow that makes the Trump regime look sane. There’s such a thing as too much teen spirit.
