"The current pro-natalist project is weaponizing an imaginary rural America in ways that harm real rural Americans today."

My DeJong Lecture, and the others in the 20th anniversary event, is now available: "How pro-natalist policies harm rural Americans."

This new briefing paper from a larger team of demographer coauthors led by @amandajean.bsky.social complements the @theconversation.com piece three of us wrote last month described in the thread below.

I found this out because there were these weird off-hand comments in the population projections from the era. I was shocked that they thought fertility rates would remain at or near Depression levels in the 1940s and 1950s.
But of course they did! We always think the future will be like the present.

Did you know that in the 1930s and 1940s elites across society were wringing their hands about birthrate decline? Just like today they attributed their low fertility (BELOW REPLACEMENT, SHUDDER SHUDDER) to individualism, urbanization, consumerism, selfishness, etc.

This paper discusses it nicely.

Repeated headlines about population collapse got you worried? @amandajean.bsky.social and a team of demographer colleagues (including me) on why you should rest easy in the face of the pronatalist panic.
Are we doomed to a demographic destiny of decline because ladies aren't having babies? No.

We've been here before. It turns out that population projections only describe one of many possible futures. Our actual future is still to be written.

Feeling alarmed over dire long-term population projections that suggest humanity will disappear? Don't be!

Demographers generally aren't worried, and you shouldn't be either. @amandajean.bsky.social explains why in this great @ccfamilies.bsky.social brief.

But the kind of crisis that pronatalists say requires state policy interventions in childbearing decisions isn't supported by evidence or good social science.
7/

There can be a good case for adjustments to economic and labor policies, family support, education investments, and immigration to adapt to changes in the age structure of the population, and to help families reach their desired number of children.
6/

Nor is there any current reason to expect medium-term decline in the US population in particular, or the crises pronatalists imagine about the labor force. Some of their ideas risk making labor force problems *worse* by reversing gains in women's labor force participation.
5/

"Most population scientists avoid making such long-term projections, for the simple reason that they are usually wrong. That’s because fertility and mortality rates change over time in unpredictable ways."
4/

Pronatalists overestimate the precision of long-term projections of fertility rates, assuming that once they've fallen they will stay low forever.
3/

The public pronatalism discourse misunderstands how an important measure of fertility works and what it does and doesn't tell us. It relies on a measure, the total fertility rate, that *necessarily* underestimates lifetime fertility during a transition to childbearing at older ages.

My coauthors @lesja.bsky.social @karenguzzo.bsky.social & I have a new piece in @theconversation.com , which offers insights into why most demographers do NOT think there is a current fertility crisis and the panic about population decline is unwarranted.

Fears that falling birth rates in US could lead to population collapse are based on faulty assumptions
While the changes in population structure that accompany low birth rates are real, the impact of these changes has been dramatically overstated.

We are so glad to see this important conversation gaining traction. The fear-mongering around “population collapse” is not only overstated — it’s often rooted in outdated or biased assumptions.

Limiting women's access to contraception undermines their reproductive autonomy leading to *both* more unintended births and fewer wanted births.

5/5

The rural-urban gaps aren't explained by other differences in women's characteristics. We argue that they're explained by differential access to other forms of contraception or abortion that allow control over the timing of childbearing.
4/5

So significantly more rural women who want to have another child find that they are unable to do so.
3/5

Tubal ligation is difficult and expensive to reverse, but 20-25% of women with ligations later want additional children.

Rural women are almost twice as likely as suburban or urban women to receive tubal ligations.

2/5

Now online open access at Perspectives on Sexual and Reproductive Health: my article with Zoe Levy showing that limits on contraception and abortion access in rural America lead more women there to opt for tubal ligation and end up unable to have wanted children later.
