I've noticed that for my class (I'm pushing 40), people either got kids when they were 16-20, or well after 30. Something like one third of our class had their first child around age 32-35...lots of COVID children!
In our case, there's a pretty clear divide between those that went straight to the workforce after HS, and those that pursued college/university, and typical professional jobs. With the latter being those that become parents late.
Those that I still know very close, and have been in the same situation, have all told the same story:
- Studied for 5 years to get a masters degree
- Worked for some years, until they found their career job
- Wanted to travel and focus on themselves, now being more financially secure and having more spare time to do so.
And suddenly they were 30.
- Spent some time finding a partner they wanted children with. Spent a year or two doing couples stuff, before a kid would take up all their time.
And that's pretty much how you end up as a first-time parent almost in your mid 30s.
Another observation is that around half of the guys have still not had any children, while around 75% of the women have become parents.
The redistribution of “child free” & “not yet parent” from 2017-2023 is massive… a shift of over 10%.
I see this anecdotally in my Gen Z/Millenial friend groups, but the numbers backing the observation up is wild.
But frankly, I understand it. One of our main pain points for not having kids yet is the cost of childcare (US). That’s not getting better anytime soon, either, from what I can tell.
Is the cost of child care a cause, or is it a symptom of a deeper problem? The decline in the fertility rate is not an isolated phenomenon, and it spans many disparate cultures. I know this opens a can of worms, but perhaps we should be more open to the idea that maximizing the labor force participation of both sexes by outsourcing child-rearing is a suicidal model. It manifests as a gradual change in behaviors that we, in our hyper-individualistic society, tend to attribute to personal choice, but I don't think so many people would go "child-free" if we didn't frame child-rearing as a low-value trap that isn't worth sacrificing a professional career over. The supply constraint is a consequence of that value shift.
I think your presumption that parents rather work than be a stay at home parent seems flawed compared to a reality that having a dual income household is a requirement to a middle class lifestyle. I know very few parents that would rather work than hang out with their kids.
I think people fixate on the directionality too much, at this point it is a self-reinforcing cycle. I don't know how to break it, but I'm not optimistic about the half-hearted attempts of some countries to address it via subsidies and tax breaks.
> I know very few parents that would rather work than hang out with their kids.
Work being a proxy for resources, most people want both. The value shift I mentioned earlier affects the extent to which we prioritize one or the other. Given the same economic environment, a society where family is viewed as more important than material comfort would have more families sacrificing income rather than just talking about it.
>know very few parents that would rather work than hang out with their kids.
But they would work to increase the odds of securing a house in a more expensive neighborhood to increase the odds their kid is surrounded by more well heeled children for myriad reasons which then results in higher chances of getting into the best schools to increase the odds they are able to earn a high income due to possessing the right signals and knowledge.
And they would reduce the number of children they have to maximize the odds for the one or two they do have.
Economically housing costs are huge, because as soon as you have kids you really start to want more stability and space. Small apartment hopping is easy and even kind of fun when you have no kids but things change dramatically when kids arrive.
Interesting data showing a trend of less people wanting children at all. What I want is the reasoning for not wanting children broken down, that is the crux of the issue and while its good to see a breakdown to the barriers for those wanting children I feel like the not wanting isn't as simple as just no.
Birth rates in the UK are now, according to the ONS, at their lowest levels since records began in 1938, at a rate of 1.44 children per woman. With a rapidly ageing population, migrants will be essential to replace UK-born workers - https://www.tradeandbusiness.uk/news/six-reasons-why-the-uk-...
It's like an iterated prisoner's dilemma, but one prisoner refuses to defect or learn anything, despite the other constantly defecting.
as someone who squarely falls into the “probably don’t want kids because of overpopulation” category —
i get the irony you’re trying to point out. but global overpopulation is not the same as national overpopulation.
at some point we’re gonna run out of fucking food as a species. *
the sooner we can get our heads out of our arses and past the primitive tribalism of “we need to have more than the other lot” as a species, the better.
i squarely fall into the “migration is the solution, not the problem” camp too [0]. exactly because of that global perspective.
plenty of people in the world. maybe it’s time we learned to share as a species? although fuck all chance of that happening any time soon in the current political climate.
* someone usually attempts a retort about “technology will magically save all of us” to this point. which is just kicking the can down the road.
[0]: edit to note that the problem i’m referring to here is national underpopulation specifically
But migration doesn't do anything to address global overpopulation. The places with population growth don't change [1], so they keep producing excess population. If anything, it makes addressing overpopulation much much harder - without immigration, each country can address overpopulation on its own. With immigration, they have to globally coordinate, and anyone who complies will be displaced by those who defect. Coordinating anything on a global scale is hard, but practically impossible when defection is incentivized.
updated with an edit about migration is a solution for national underpopulation specifically. (do t want anyone else to get confused about it).
i wasn’t clear on that do i can see why you’re now arguing this point.
on global overpopulation — i disagree. the only way to solve it is to co-ordinate globally. and that involves helping everyone else who doesn’t hsve stuff getting to a place of yeah we’ve kind of all got enough stuff now.
or, alternatively, somehow everyone getting to a place where we realise “stuff” is abjectly meaningless and pointless as a measure for our individual/group success.
basically, materialism needs to fuck off as our dominant incentivising thing.
> on global overpopulation — i disagree. the only way to solve it is to co-ordinate globally. and that involves helping everyone else who doesn’t have stuff getting to a place of yeah we’ve kind of all got enough stuff now.
Here we agree. I should clarify there are multiple types of coordination - the kind you propose is the easier one. It can be global, but it really only needs two countries - one offering aid [1], and one receiving it. If someone defects, no big deal - someone else might step in, and in any case, the situation should be better than if there had never been aid in the first place.
But getting every population on Earth to agree to and follow through with reducing their own fertility is the much harder kind of coordination. There will always be defectors, and these defections will (literally) add up and multiply. Unlike with aid, where the giver is only sacrificing as you say materialism, now their worry will be "will my group continue to exist?"
[1] Whatever form that aid takes. There are arguments that simple material aid does more harm than good and hinders development, but surely there are forms of aid that help development, so this is not an excuse to stop aid entirely.
That's an oversimplification, otherwise all organisms would lay massive clusters of eggs like insects. There would be only R-selected organisms, no K-selected.
It's long term average successful fertility over time.
Fair enough point. However, any species (or subpopulation of a species) that reproduces below replacement level is going to die off. Long-term, that means cultures, mindsets, and so on that reproduce at or above replacement level will eventually dominate and cultures that reproduce below that level will eventually cease to exist.
in the uk it was estimated we only have 100 or so harvests left on current farm land [0]. globally, the estimate is worse - 60 harvests [1]. 3.2 billion people are currently affected by soil degradation and its downstream effects [1 follow the links]. now there are initiatives being taken to try and address this specific problem, but this isn’t the only problem.
we have finite resources on this planet and we are out of balance with our surrounding environment. one way or another, it’s gonna catch up to us.
to quote one of my favourite NOFX tracks [2]: There's no more points of view when your only thought is food
Some problems need tackling at the right time. We don't need to get too crazy about declining populations when we are facing more urgent issues. Maybe the world in 2050 will be so different that the issue has resolved itself.
Always remember that the world was fine with 2bn people just 100 years ago.
The concern with demographic collapse isn't that the world won't be fine with fewer people, it's that the transition period is going to be extremely painful.
During the increase in population kids are helpless for ~8 years before they're actually able to contribute to farms and whatnot, so the large number of extra children doesn't show. During demographic collapse, since it happens generally as life expectancies go up, elderly adults generally (with exceptions) spend decades getting less and less able to contribute before they die. We don't have answers for how to take care of them during that window.
Unless someone invents some kind of amazing robots like the promise of Tesla Bots except completely real, the only way to take care of older people is to have younger people taking care of them. (That includes younger people engaging in heroic lifesaving medical services for older people.)
Eventually this would be a self-correcting problem, but in the most gruesome way one can imagine. And creating and maintaining Tesla Bots would require lots of young people, too... unless/until one finds a way to make them create and maintain themselves, which seems rather far off; I live in a world where computer servers don't really even maintain themselves.
I tend to take the opinion that we already dug our grave.
It's not that different that the deserved skepticism for new "climate friendly" technologies. "The totally unsustainable behavior you had was bad. Here, have a slightly better option that allows you to keep doing the totally unsustainable thing with a slightly smaller footprint."
Electric cars. Organic meat. Carbon offsets for flights. LEED certified McMansions. Every time we tell people the change isn't going to hurt, we lie to them. What we need are car-free communities, plant based diets, less travel, and smaller homes.
Overpopulation isn't that different. Population reduction will hurt, but that doesn't mean it isn't necessary. I fully expect to get a lesser quality of care in my old age than my parents got. That sucks, but, that's reality. We're now in the consequences stage. We should be focusing on mitigating harm, not clinging to populating the planet in the way we used to.
That assumes that working until 75 is feasible for a significant chunk of the population. I don't have stats, but anecdotally I would say that it's not in the US.
> Always remember that the world was fine with 2bn people just 100 years ago.
we’ve gone from ~2 billion to ~8 billion in 100 years.
compared to the (highly estimated) figures from before 100 years ago — that’s a massive increase.
the graph is basically a line going straight up compared to the rest of (highly estimated) population data for the last 10k years. and growth is continuing.
> Maybe the world in 2050 will be so different that the issue has resolved itself
“maybe a miracle might happen” — is just kicking the can down the road in my book.
we are out of balance with our surrounding environment. there will be a readjustment — whether we choose to make that readjustment ourselves (take responsibility for the problem), or let the readjustment happen (the problem really becomes a problem), is up to us as a species.
> Some problems need tackling at the right time.
some problems take a really long time and a lot of effort to work on so maybe starting to work on them early and proactively might be a good idea. like climate change.
> We don't need to get too crazy about declining populations when we are facing more urgent issues.
speaking of climate change, global overpopulation kinda has an impact on it! more people -> use more resources -> screwing up the planet faster
Your arguments are a bit all over the place for me to follow. I don't think it is kicking down the can if you don't have enough information to not get to much into panic mode.
If this turns out to be an issue we can act. At the moment it looks like it to me that the climate crisis is more relevant than the demographic change, because as you said: Less people are actually better for the planet.
With AI becoming more capable each year we might find that many of the issues of large elderly populations can be alleviated.
Let's check back in 5 or 10 years if the demographics is really shaping up to be a problem.
One argument is that an aging population will be set in its ways and not able or willing to adapt. If people think they can't afford to fix their own building to save their own lives
how can you expect them to sacrifice a single penny to address problems like climate change that will affect future generations? Granted, fewer people in itself reduces our environmental impact, but some combination of young people and older people who feel invested in their offspring is necessary for us to face the future.
The problem is economic and political. Witness the riots that took place in France when they even talked about raising the retirement age.
If population declines that much, retirement will become structurally impossible for anyone but the relatively wealthy. Other types of social safety nets will also collapse, because at some point young working people will just balk at the tax burden they'll have to pay to support them with a shrinking cohort of workers.
AI and automation could cushion the blow to some extent.
Those wealth transfers happened informally before the government formalized them. Social security takes a burden off young people as much as it gives to old people.
Elder abuse is widespread in Confucian societies like Japan and China, it's the dark side of a culture that professes filial piety but actually breeds resentment in the young.
A wealth transfer from child to parent / relative is different than a wealth transfer from young person to the collective of old people, apportioned wealth based on complicated and changing formulas.
There exists an arbitrage opportunity where one can avoid the costs and compromises of coupling/parenting, and still retain some of the benefits.
> Social security takes a burden off young people as much as it gives to old people.
I don’t see it this way. If I were given the choice, I would not pay the government at all, and I would not expect anything from the government in the future. I already don’t, by way of knowing that my future benefits will be decreased in purchasing power via devaluation of currency and increased retirement age and changes in the benefit formula.
And it wouldn’t change my burden at all, because I didn’t ask to be born, hence I don’t owe anyone in their old age (nor does anyone owe me in my old age).
We are nowhere near running out of food. Famines are largely political in origin, as are other forms of scarcity, usually resulting from trade embargoes and wars.
I would have been worried about energy before we cracked cheap solar power and cheap batteries. At this point we have the technology to power ourselves off the sun even if we lack the political will to migrate to it quickly.
Climate change is a danger but I do not believe it's existential unless we really do continue to burn carbon all through the 21st century without migrating to other energy sources and just DGAF. Climate change will cause regional disasters and migrations and political instability but I don't think it's going to cause any more death or suffering than large scale wars. (It may cause large scale wars.)
If we did in fact have 1950s levels of global population growth ongoing, we would eventually hit major problems, but that is just not happening. The only place left with high birth rates is Africa and their birth rates are falling like everyone else's as they develop and urbanize.
For some strange reason this line of thinking had tremendous influence on the left, at least in the West, despite the fact that there has always been a huge undercurrent of racism in overpopulation discourse. This pod does a decent job calling that out. I remember watching an overpopulation alarmist documentary as a teenager and thinking -- without any prompting -- that the whole thing came off as super racist. Any time they wanted to show the looming population catastrophe they always showed hordes of people with dark skin.
Ehrlich continues to be treated like an economist -- meaning, given intellectual credibility despite a track record of having been consistently wrong.
This doesn't mean I buy into underpopulation hysteria either. I see them making the same mistake: assuming that current trends will continue indefinitely.
It's entirely possible that things like the childfree movement will cause a population rebound. How? By selecting out of the gene pool whatever traits make people more reluctant to reproduce. Until recently reproduction was pretty automatic, allowing those traits to persist, but after a few more generations of reproduction being solidly optional we could end up with a population composed of almost 100% people with intense "biological clocks" and a strong urge to have babies. The present decline in fertility could be like a "bear trap" on a bull market stock graph.
I don't see the humor you're seeing, there's no hypocrisy because the two messages are coming from two very different groups with very different values and motivations.
The "we need more people" stuff is coming from the capital class and their sycophants. They want more people so they can have more laborers to drive down the cost of labor, and more consumers to buy more product, and more renters to drive up the price of rent. They want population number to go up because they are invested and committed to the numbers go up game. As long as more people means more numbers go up, that's what they'll keep demanding. The UK has more people than ever before, it's steadily climbing but they always want even more. Unbounded growth.
The "I don't want kids because this place is crowded" and "kids are too expensive" messages are coming from members of the general public who are dealing with the ramifications of the policies of the first group. Their rent is high, their towns and cities growing, traffic is getting worse, city buses are packed, there's lots of things they want to buy but the value of their labor isn't keeping pace. Birth rate falls in response to these pressures, so the capital class tries to import new labor from poor parts of the world, knowing those new laborers will feel relatively happy to live 10 people to an apartment working for piss poor pay, because those conditions are still an improvement over where they are coming from.
not sure how thats relevant. planet is still overpopulated. Its not like someone polluting the planet in uk will only pollute uk. we all share the same global atmosphere.
Chances are if you keep pulling people out of places with high birthrates they will continue to have high birthrates and you will continue to have the low birthrates fueled by people who feel there's no space for their childwish.
Left high school in the UK thinking that anything connected with family and having children was some type of carnal sin. Seemed the idea of anything traditional was an aboslute taboo to most of the staff. When I compare schooling experiences to people from other countries, it seemed everything was so negative and guilt-ridden in comparison.
This is definitely a belief system isolated to certain social classes. Lots of other classes of people thinking having children is great, love going to children's birthday parties, get excited when a relative is expecting a baby, and so forth.
I think it’s self-sustaining, in that the needs of people without kids and the needs of people with kids are super duper different. If all your friends don’t have kids and you do, you feel ostracized because they’re not going to rearrange their life over your kids, and you’re constrained by your kids’ schedules (particularly sleep), so you just don’t see them that much anymore. Conversely, if all your friends have kids and you don’t, most of their socializing will probably feel really alien to you (unless you’re a teacher or something and work with kids), so you’ll feel disconnected from them.
Anecdotally, in my friend group, once the first two people had kids and started hanging out with each other, it was like the flood gates opened.
you are assuming that people who have them are making conscious choice to have them. I live in india and everyone here has them by default, there is no flowchart with a diamond. its just something ppl do, like going to the bathroom.
in the west answer is that there are more forms of entertainment and fulfillment available now and there is actually a flowchart with diamond in it.
In China, having large families in the 1950s/1960s was a deliberate policy decision, which is how they ended up being a billion-plus today. (Which was then followed by a one-child policy to try to correct that, since the number of people in China exceeded the amount of arable land to support such people, and once Mao Zedong was out of power, smarter people decided "hmm, it's going to be a big problem if we get to 3 billion people".)
What was the large family policy? I know about the one-child policy, but I don't think people needed a policy to have large families, it used to be the norm back then even outside of China.
In short, Mao Zedong thought that having a big population would lead to a stronger state. Keep in mind this is the same guy who declared war on sparrows as being "capitalist birds".
Because they have? Gained doesn’t mean they are completely at par with men. But many have increased their agency relative to women in India in decades past. Many can now get an education, have their own income, live by themselves.
Not all, obviously a few hundred million are still probably not close to economic freedom, but more are than before.
sure but how did you relate that to birthrates. did you correlate any datapoints to make that hypothesis about india?
like did you look up who many women voluntarily 'live by themselves' in india ?
The second link in my post above. Although, if you live in India, you should be able to see women in the cities with jobs that can support themselves. This was not as ubiquitous even just 40 years ago.
yes i live in a major city and i've never seen a woman live by herself. like not even a once.
anyways i wasn't contradicting that there are more women working now ( which is not actually true ) . I was asking how you correlated that to birth rates .
these two graphs aren't exactly telling the same story
The rest of the developed world is far more advanced in demographic decline, but it surprises me that we don't see this kind of statistics from other countries. In southern europe, i have not seen diligent and in-depth surveys about demographic trends. The public policy measures taken are crude, handwavy and populist measures which mostly fail
Different but related topic, Hungary has recently moved forward with a program reducing the tax burden of mothers up to I believe exemption from income taxes for life for those that have 3 or more kids. This seems to be a pretty solid idea with so many people putting off having children due to the associated costs.
That's performative policy. Hungarian mothers of 3 weren't paying much or any taxes at all in the first place. Because on average they have a small or no income.
I think a better policy would be to reduce the tax burden of a couple with 3 children. This makes working quite lucrative whilst at the same time it creates the flexibility for the couple to distribute work how they see fit, whether this is a breadwinner model or more hybrid.
Pinning this to the mother doesn't work. The policy incentive is to work as much as possible whilst at the same time carrying the burden of 3 children. Not an attractive combination.
Immigration laws are not relaxed in Europe. The aftermath of a bunch of middle eastern wars pushed a huge number of people towards Europe, followed by another European war that did the same.
The EU allows free movement but it's pretty hard to get a working visa without a job.
It’s always been interesting to me that healthcare for kids is not as popular as healthcare for old people, such that there is no Medicare for kids. There is Medicaid, but it pays healthcare providers less…why?
I would prefer this than having my country die or resorting to importing millions of people with completely different cultures. Those same 3 kids then go on to become tax payers, ensuring that there is a tax base in the future. So its a long term investment if you actually still want a country.
Your view is going to change depending if you look at the short or long term.
You might not like the culture of the kids raised by moms specifically incentivized by money to have kids, who may or may not be interested or able to raise the kids well.
It has always been trivial to pay a woman to give birth. Incentivizing the creation of productive families with well raised children is the difficult part.
Sure, there are positives and negatives to every single situation.
But the absolute erasure of the population of a country is my concern.
I'm not in the business of telling people how to raise their kids but I support incentivizing people to have kids.
There was an interesting study earlier this week that is essential to this discussion.
I'm afraid I don't have the link but the gist was that most couples do ultimately want and have children. Slightly too less for population replacement but still. However, the far more alarming issue is the lack of couples. Couple forming is falling off a cliff.
In our case, there's a pretty clear divide between those that went straight to the workforce after HS, and those that pursued college/university, and typical professional jobs. With the latter being those that become parents late.
Those that I still know very close, and have been in the same situation, have all told the same story:

- Spent some time finding a partner they wanted children with. Spent a year or two doing couples stuff, before a kid would take up all their time.
And that's pretty much how you end up as a first-time parent almost in your mid 30s.
Another observation is that around half of the guys have still not had any children, while around 75% of the women have become parents.
One of my classmates didn't go the academic route. She has a 25 year old kid now.
The others, one had a kid late 20s. Most of the class was mid to late 30s. Several had their first kid past 40.
Only two had more than two kids, but they were a couple who met in school.
Nobody has four kids.
There's still only one person who has an adult (18+) kid.
I see this anecdotally in my Gen Z/Millenial friend groups, but the numbers backing the observation up is wild.
But frankly, I understand it. One of our main pain points for not having kids yet is the cost of childcare (US). That’s not getting better anytime soon, either, from what I can tell.

And they would reduce the number of children they have to maximize the odds for the one or two they do have.

we’ve gone from ~2 billion to ~8 billion in 100 years.
compared to the (highly estimated) figures from before 100 years ago — that’s a massive increase.
the graph is basically a line going straight up compared to the rest of (highly estimated) population data for the last 10k years. and growth is continuing.

> Maybe the world in 2050 will be so different that the issue has resolved itself
“maybe a miracle might happen” — is just kicking the can down the road in my book.
we are out of balance with our surrounding environment. there will be a readjustment — whether we choose to make that readjustment ourselves (take responsibility for the problem), or let the readjustment happen (the problem really becomes a problem), is up to us as a species.
> Some problems need tackling at the right time.
some problems take a really long time and a lot of effort to work on so maybe starting to work on them early and proactively might be a good idea. like climate change.
> We don't need to get too crazy about declining populations when we are facing more urgent issues.
speaking of climate change, global overpopulation kinda has an impact on it! more people -> use more resources -> screwing up the planet faster
If this turns out to be an issue we can act. At the moment it looks like it to me that the climate crisis is more relevant than the demographic change, because as you said: Less people are actually better for the planet.
With AI becoming more capable each year we might find that many of the issues of large elderly populations can be alleviated.
Let's check back in 5 or 10 years if the demographics is really shaping up to be a problem.

how can you expect them to sacrifice a single penny to address problems like climate change that will affect future generations? Granted, fewer people in itself reduces our environmental impact, but some combination of young people and older people who feel invested in their offspring is necessary for us to face the future.
If population declines that much, retirement will become structurally impossible for anyone but the relatively wealthy. Other types of social safety nets will also collapse, because at some point young working people will just balk at the tax burden they'll have to pay to support them with a shrinking cohort of workers.
AI and automation could cushion the blow to some extent.
But then leaders started promising the old people (majority of voters) wealth transfers from the young people.
And that will cause friction, because these wealth transfers only made sense with growing proportions of young people.
Elder abuse is widespread in Confucian societies like Japan and China, it's the dark side of a culture that professes filial piety but actually breeds resentment in the young.
There exists an arbitrage opportunity where one can avoid the costs and compromises of coupling/parenting, and still retain some of the benefits.
> Social security takes a burden off young people as much as it gives to old people.
I don’t see it this way. If I were given the choice, I would not pay the government at all, and I would not expect anything from the government in the future. I already don’t, by way of knowing that my future benefits will be decreased in purchasing power via devaluation of currency and increased retirement age and changes in the benefit formula.
And it wouldn’t change my burden at all, because I didn’t ask to be born, hence I don’t owe anyone in their old age (nor does anyone owe me in my old age).
I would have been worried about energy before we cracked cheap solar power and cheap batteries. At this point we have the technology to power ourselves off the sun even if we lack the political will to migrate to it quickly.
Climate change is a danger but I do not believe it's existential unless we really do continue to burn carbon all through the 21st century without migrating to other energy sources and just DGAF. Climate change will cause regional disasters and migrations and political instability but I don't think it's going to cause any more death or suffering than large scale wars. (It may cause large scale wars.)
If we did in fact have 1950s levels of global population growth ongoing, we would eventually hit major problems, but that is just not happening. The only place left with high birth rates is Africa and their birth rates are falling like everyone else's as they develop and urbanize.
Here's a good pod on the subject:

For some strange reason this line of thinking had tremendous influence on the left, at least in the West, despite the fact that there has always been a huge undercurrent of racism in overpopulation discourse. This pod does a decent job calling that out. I remember watching an overpopulation alarmist documentary as a teenager and thinking -- without any prompting -- that the whole thing came off as super racist. Any time they wanted to show the looming population catastrophe they always showed hordes of people with dark skin.
Ehrlich continues to be treated like an economist -- meaning, given intellectual credibility despite a track record of having been consistently wrong.
This doesn't mean I buy into underpopulation hysteria either. I see them making the same mistake: assuming that current trends will continue indefinitely.
It's entirely possible that things like the childfree movement will cause a population rebound. How? By selecting out of the gene pool whatever traits make people more reluctant to reproduce. Until recently reproduction was pretty automatic, allowing those traits to persist, but after a few more generations of reproduction being solidly optional we could end up with a population composed of almost 100% people with intense "biological clocks" and a strong urge to have babies. The present decline in fertility could be like a "bear trap" on a bull market stock graph.
The "we need more people" stuff is coming from the capital class and their sycophants. They want more people so they can have more laborers to drive down the cost of labor, and more consumers to buy more product, and more renters to drive up the price of rent. They want population number to go up because they are invested and committed to the numbers go up game. As long as more people means more numbers go up, that's what they'll keep demanding. The UK has more people than ever before, it's steadily climbing but they always want even more. Unbounded growth.
The "I don't want kids because this place is crowded" and "kids are too expensive" messages are coming from members of the general public who are dealing with the ramifications of the policies of the first group. Their rent is high, their towns and cities growing, traffic is getting worse, city buses are packed, there's lots of things they want to buy but the value of their labor isn't keeping pace. Birth rate falls in response to these pressures, so the capital class tries to import new labor from poor parts of the world, knowing those new laborers will feel relatively happy to live 10 people to an apartment working for piss poor pay, because those conditions are still an improvement over where they are coming from.
no
comments mentioning immigrant birthrates below misunderstood what is being talked about here.
> they will continue to have high birthrates
'they' here is not immigrants , they here is ppl in the places where immigrants came from.

Anecdotally, in my friend group, once the first two people had kids and started hanging out with each other, it was like the flood gates opened.
in the west answer is that there are more forms of entertainment and fulfillment available now and there is actually a flowchart with diamond in it.
In short, Mao Zedong thought that having a big population would lead to a stronger state. Keep in mind this is the same guy who declared war on sparrows as being "capitalist birds".

thank god!! its suffocating over here.
curious why do you think women have gained economic and social freedom in india?
Not all, obviously a few hundred million are still probably not close to economic freedom, but more are than before.
anyways i wasn't contradicting that there are more women working now ( which is not actually true ) . I was asking how you correlated that to birth rates .
these two graphs aren't exactly telling the same story

I think a better policy would be to reduce the tax burden of a couple with 3 children. This makes working quite lucrative whilst at the same time it creates the flexibility for the couple to distribute work how they see fit, whether this is a breadwinner model or more hybrid.
Pinning this to the mother doesn't work. The policy incentive is to work as much as possible whilst at the same time carrying the burden of 3 children. Not an attractive combination.
The EU allows free movement but it's pretty hard to get a working visa without a job.

It’s always been interesting to me that healthcare for kids is not as popular as healthcare for old people, such that there is no Medicare for kids. There is Medicaid, but it pays healthcare providers less…why?
Your view is going to change depending if you look at the short or long term.
It has always been trivial to pay a woman to give birth. Incentivizing the creation of productive families with well raised children is the difficult part.
You are of course welcome to disagree.
I'm afraid I don't have the link but the gist was that most couples do ultimately want and have children. Slightly too less for population replacement but still. However, the far more alarming issue is the lack of couples. Couple forming is falling off a cliff.
