Birthrates are falling worldwide, and rapidly. We're already at a point where the birth rate worldwide is just at replacement level - the current growth in population is due to increased lifespans from 1-2 generations ahead of the flattening. Only a handful of desperately poor countries - places like Yemen and Afghanistan - have high birthrates. To give a sense of how much it's changed, Iran's birthrate is lower than Europe or the US. In 1980, Iran's birthrate was four times higher than it is now.

This. It's quite clear that the fertility rates we've seen historically will not hold into the future. We are on a timer to figure out why we're structuring society in a way that so many people find repulsive enough to not wish to reproduce.

This is not a Western or first world problem, because we see it spreading as countries become more developed. In many ways, I would argue that this is an exponentially bigger problem than climate change, although I am sure there is some overlap since there mere psychological pessimism from how the media/pre-university education handles climate change is enough to get people to not want to reproduce.

I don't see it as a problem, myself. Children have gone from economic boon (more child labor to help the family) to economic expense. It makes more sense to parents to have one or two kids and pour resources into them, rather than having a half-dozen, half of whom will die as children. And for adults who aren't really infatuated with parenting, they can skip it altogether, not needing children to care for them in their old age.

We're at around 2.5 according to:

And there are lots of countries in Africa that have high rates:

Yes. Desperately poor ones. And most of them are improving, rapidly. The process takes a couple of generations, once it gets rolling.

Take Egypt, for example. Its birth rate is currently 3.26, which is "high". but That's down from 6.72 in 1960 and 5.60 in 1980. Over the same period, life expectancy has risen from 48 to 71. This means population growth hasn't changed that much, from 2.8% to 1.9% - but as birth rate continues to fall and life expectancy levels out, it'll go negative, just like it did in the US and Europe, which would have negative growth, were it not for immigration.

Think this nations are just doomed and can't get any better? In the mid-19th century, places like Sweden and England had birthrates above 6, and 90% illiteracy rates. They got better. The "third world" is dropping its birth rates and increasing its economic standing far, far faster than Europe did.

edit: Over the same-ish 1965-present period, Egypt's per capita GDP grew from $165 to a recent peak of $3548, about a 20x improvement (this is constant dollars). So wealth goes up, life expectancy goes up, birth rate goes down. These things are linked in virtually every nation.

> Think this nations are just doomed and can't get any better?

I'm not sure if that question was directed at me or to all readers, but if directed to me, no, I certainly don't think that.

> So wealth goes up, life expectancy goes up, birth rate goes down.

Indeed, there is a strong and important link there.

Belief that the poor nations of Africa and Asia and the rest of the "third world" are simply doomed to poverty and suffering is widespread, even among educated and sensitive people. That's why I always make a point of showing that, a century from now, a place like Egypt today could be the Sweden of tomorrow.

No.

No what? Are you disputing any of the facts stated here? I'll give you my reference... Factfulness, by Hans Rosling.

If you seriously intend to disagree, cite sources. If you're just saying no to something that is a demonstrably true, objective fact... maybe ask yourself why that is.

"We're already at a point where the birth rate worldwide is just at replacement level" - that's just false.

Ok, for sake of argument, I'll give you that, although the UN disagrees - they expect the number of babies born per year to be about the same 100 years from now as it is today.

Looking into this more, I got some UN statistics on historic and projected crude birth rates. In 1950, it was 37.2. Today, it's 18.2. They project 13.4 by 2050. Population growth drop lags birth rate drops, due to increased lifespans worldwide. As the last generations of high birth rate get past childrearing years, it'll just go down more.

So yes, the birthrate still outstrips the death rate - but at some point in the 21st century, those numbers will flip, and they've been converging for over 50 years now.

Falling, but slowly (and it also trends up at times). The vast majority of people become parents.
