Everyone's least favorite psychopath took a shot at my pal @mikeduncan.bsky.social last night so here are some charts. Make sure to read the alt text for details. Lyman is full of it and there is no realistic scenario to get to a 2.0+ TFR w/o a massive reversal in the huge teen pregnancy rate drop.

Lyman Stone 石來民 🦬🦬🦬 @lymanstoneky speaking as the lead researcher at the Pronatalism Initiative and a big fan of mike duncan's podcasts, nope, getting teenagers to have more babies is not the plan. Quote Mike Duncan . @mikeduncan · 14h Replying to @mikeduncan Instead we see the real game. A combination of outlawing abortion and vastly restricting access to contraception will lead Change in births per 1,000 female population since 1995. Birth rates for 30 and over have risen, while birth rates for under 30s have fallen. The biggest drops have been in 15-19 (-42.9) and 20-24 (-48.3). Charts showing birth rate per 1,000 female population from 1995 to current and total fertility rate (births per female) since 1995. In both instances, a counterfactual scenario assuming the same birth rate for those aged 19 and younger eliminates more than half of the decline in total birth rate. A counterfactual scenario showing how much non-teen birth rates would have to rise in order to make up for the decline in teen birth rates since 1995. Births per 1,000 20+ female population would have to go from 50.8 to 57.0. In reality, this number has declined.

Globally the FTR is still above 2.4. If you look at the distribution there seems to be a huge correlation with life opportunities as perceived by the relevant age group. Perhaps we should turn that knob, right?

LMAO because they squawked about that for years. THEN they claimed single parents would cause crime. Then the crime rate dropped. So now they pretend we’re ‘facing human extinction’ (though planet will have 2 billion more humans in the next 50 years) and crime is up (it is down to 1950s levels).

I mean surely as a mathematical matter if 20-29 went up enough it would go over 2? but I do agree that is what Stone is aiming for

Would likely need to happen mostly in the 20-24 cohort, which would also be bad. The changes overall (both the drops and the increases) represent people having more control over their reproduction.

Change in fertility rate by age cohort between 1990 and 2019. The change is positively correlated with age (dropping for the youngest cohorts, increasing for the oldest)

I really think that’s an overemphasized aspect, which is why you don’t typically see much impact on TFR from subsidized childcare etc. I really doubt there are a bunch of 22 year olds who want kids but can’t swing daycare. It’s a broader issue of autonomy and opportunity.

Just anecdotally if you are having kids 20-24 you are probably relying on your family network to provide child care.

Mathematically, yes, you could make it happen. That's the point of the last chart! But nobody arguing for higher fertility rates now says "what I mean is a fertility rate for non-teens substantially above 30 years ago" or "teen pregnancies way up". You *must* pick one of those two.

We should do a lot of stuff the pro-natalists want in terms of expanding the social safety net for parents and children, no doubt. But very very unlikely that will raise the birth rate much. see a really good recent Max Fischer pod on this (transcript included)

yeah I've seen that research, but I agree with Steve Waldman that if you actually wanted to move the needle with benefits they would likely have to be many times larger that even what the Nordics give out drafts.interfluidity.com/2024/02/06/d...

tbc we should increase those benefits regardless of the implications for natality. but the point the pod makes is that it doesn't appear increasing benefits has helped *anywhere*.

I think that's overstated, see this paper. I'd guess that if we did a year of paid leave, big child allowance, free daycare, and universal Medicare it would have a pretty large effect given the atrocious status quo www.unfpa.org/sites/defaul...

I am sure it would have a positive effect. But the point of the numbers above is to show that if you rule out teen pregnancies, you need enormous effects to get to a replacement rate, and there's zero evidence any policy can do that.

Waldo @waldo42.bsky.social

A marginal but real effect could come from vehicle design. Families are purposely capping at 2 kids so they don't need to get a bigger boat or otherwise solve the car seating problem. As much as teen pregnancy is down, so too are bigger families.

My argument isn't that we shouldn't support families. My argument is that targeting a TFR of 2.1 or so is a complete waste of time and not a useful end in and of itself.

My hot take is that the most effective lever for increasing fertility would be a massive social program to get men to be better domestic partners. A lot easier to have 3 kids if both parents pull their weight.

I think it’s very possible for fertility rates to pop up again (a bit!) but it seems to have more to do with big social movement trends rather than yeah, subsidies

United States of America is doing part of “the full Ceausescu” by outlawing abortions and any other contraception. The full Ceausescu involves benefits for families including money (and increased sums for those w 5+ children and 10+ children!). (Not a fan but that’s how it was)

More and more, I think a big part of that could be accomplished with heavily subsidized or free housing for people who have more kids in their 20s. Medicare/Medicaid for all kids and parents for life and student loan forgiveness could, IMO, move the needle in the US.

I know people point to the data and say that more generous social safety net and parental support programs haven't helped much in Europe and Asia. The difference, ISTM, is that most other wealthy countries were starting from a much more generous welfare state *before* implementing natalist policies.

RNtropy @rntropy.bsky.social

I don't think it's good that the US has such a meager social safety net compared to peer nations, but one silver lining may be that implementing even basic programs like guaranteed housing, healthcare, and education for parents and children is far more effective here than other places.

jun 13, 2024, 3:19 pm • 0 0 • view

RNtropy @rntropy.bsky.social

For example, long before many wealthy countries in Europe and Asia implemented pronatalist policies they already provided citizens low-cost or free education, healthcare, and housing. ISTM new social welfare programs are less effective at changing behavior the more basic needs are already met.

Also, ISTM a lot of the cash incentives many other countries offer to parents are wholly inadequate in large part because there are many costs involved in raising children that don't show up in official statistics but that many parents see as obligatory (tutors, cram schools, sports, etc.).

I think this is particularly true for aspirational middle-class parents. For many parents in this group, the mandatory costs of childcare go well beyond food, shelter, and clothes.

RNtropy @rntropy.bsky.social

A lot of people think low cost, subsidized childcare would also help, but I'm increasingly skeptical that this would be either workable or effective in the US. There just isn't a good way to safely and ethically scale professional childcare.

Wouldn't more young immigrants also work? I think the policies not proposed to address fertility is the most interesting part. Like you could also imagine a "pro-natalist" movement encouraging child rearing during college, not even a terrible idea, but it's just not happening afaict.

I don't really know either. Just seems like having a younger population with an immigration policy oriented towards that would affect the fertility rate in a pretty obvious way.

When these charts say "births per 1,000", is that actually "births per 1,000 per year"? Just wondering about the conventions and labels, here. Demographic statistics isn't anywhere near any area of expertise of mine, but it seems like there must be an unspoken time interval
