Pronatalism – the idea that low start charges are an issue that have to be reversed – is having a second within the U.S.
As start charges decline within the U.S. and all through the world, voices from Silicon Valley to the White Home are elevating issues about what they are saying could possibly be the calamitous results of steep inhabitants decline on the economic system. The Trump administration has stated it’s looking for concepts on easy methods to encourage People to have extra youngsters because the U.S. experiences its lowest whole fertility fee in historical past, down about 25% since 2007.
As demographers who research fertility, household behaviors and childbearing intentions, we will say with certainty that inhabitants decline is just not imminent, inevitable or essentially catastrophic.
The inhabitants collapse narrative hinges on three key misunderstandings. First, it misrepresents what normal fertility measures inform us about childbearing and makes unrealistic assumptions that fertility charges will observe predictable patterns far into the longer term. Second, it overstates the influence of low start charges on future inhabitants progress and measurement. Third, it ignores the function of financial insurance policies and labor market shifts in assessing the impacts of low start charges.
Fertility fluctuations
Demographers usually gauge births in a inhabitants with a measure known as the whole fertility fee. The full fertility fee for a given 12 months is an estimate of the common variety of youngsters that ladies would have of their lifetime in the event that they skilled present start charges all through their childbearing years.
Fertility charges are usually not mounted – actually, they’ve modified significantly over the previous century. Within the U.S., the whole fertility fee rose from about 2 births per girl within the Thirties to a excessive of three.7 births per girl round 1960. The speed then dipped beneath 2 births per girl within the late Seventies and Nineteen Eighties earlier than returning to 2 births within the Nineties and early 2000s.
For the reason that Nice Recession that lasted from late 2007 till mid-2009, the U.S. whole fertility fee has declined virtually yearly, except very small post-COVID-19 pandemic will increase in 2021 and 2022. In 2024, it hit a file low, falling to 1.6. This drop is primarily pushed by declines in births to folks of their teenagers and early 20s – births which are usually unintended.
However whereas the whole fertility fee affords a snapshot of the fertility panorama, it’s not an ideal indicator of what number of youngsters a lady will ultimately have if fertility patterns are in flux – for instance, if persons are delaying having youngsters.
Image a 20-year-old girl immediately, in 2025. The full fertility fee assumes she can have the identical start fee as immediately’s 40-year-olds when she reaches 40. That’s not prone to be the case, as a result of start charges 20 years from now for 40-year-olds will virtually actually be greater than they’re immediately, as extra births happen at older ages and extra persons are in a position to overcome infertility by way of medically assisted replica.
A extra nuanced image of childbearing
These issues with the whole fertility fee are why demographers additionally measure what number of whole births ladies have had by the top of their reproductive years. In distinction to the whole fertility fee, the common variety of youngsters ever born to ladies ages 40 to 44 has remained pretty steady over time, hovering round two.
People proceed to precise favorable views towards childbearing. Very best household measurement stays at two or extra youngsters, and 9 in 10 adults both have, or want to have, youngsters. Nevertheless, many People are unable to achieve their childbearing objectives. This appears to be associated to the excessive price of elevating youngsters and rising uncertainty concerning the future.
In different phrases, it doesn’t appear to be the case that start charges are low as a result of persons are bored with having youngsters; slightly, it’s as a result of they don’t really feel it’s possible for them to turn out to be dad and mom or to have as many youngsters as they want.
The problem of predicting future inhabitants measurement
Normal demographic projections don’t help the concept that inhabitants measurement is about to shrink dramatically.
One billion folks lived on Earth 250 years in the past. In the present day there are over 8 billion, and by 2100 the United Nations predicts there shall be over 10 billion. That’s 2 billion extra, not fewer, folks within the foreseeable future. Admittedly, that projection is plus or minus 4 billion. However this vary highlights one other key level: Inhabitants projections get extra unsure the additional into the longer term they prolong.
Predicting the inhabitants stage 5 years from now’s way more dependable than 50 years from now – and past 100 years, overlook about it. Most inhabitants scientists keep away from making such long-term projections, for the easy cause that they’re normally incorrect. That’s as a result of fertility and mortality charges change over time in unpredictable methods.
The U.S. inhabitants measurement can also be not declining. At present, regardless of fertility beneath the substitute stage of two.1 youngsters per girl, there are nonetheless extra births than deaths. The U.S. inhabitants is predicted to develop by 22.6 million by 2050 and by 27.5 million by 2100, with immigration taking part in an necessary function.

Will low fertility trigger an financial disaster?
A standard rationale for concern about low fertility is that it results in a bunch of financial and labor market issues. Particularly, pronatalists argue that there shall be too few staff to maintain the economic system and too many older folks for these staff to help. Nevertheless, that’s not essentially true – and even when it have been, rising start charges wouldn’t repair the issue.
As fertility charges fall, the age construction of the inhabitants shifts. However a better proportion of older adults doesn’t essentially imply the proportion of staff to nonworkers falls.
For one factor, the proportion of youngsters underneath age 18 within the inhabitants additionally declines, so the variety of working-age adults – normally outlined as ages 18 to 64 – usually modifications comparatively little. And as older adults keep more healthy and extra energetic, a rising variety of them are contributing to the economic system. Labor drive participation amongst People ages 65 to 74 elevated from 21.4% in 2003 to 26.9% in 2023 — and is predicted to extend to 30.4% by 2033. Modest modifications within the common age of retirement or in how Social Safety is funded would additional scale back strains on help packages for older adults.
What’s extra, pronatalists’ core argument {that a} greater start fee would improve the scale of the labor drive overlooks some short-term penalties. Extra infants means extra dependents, at the very least till these youngsters turn out to be sufficiently old to enter the labor drive. Kids not solely require costly providers equivalent to training, but additionally scale back labor drive participation, notably for ladies. As fertility charges have fallen, ladies’s labor drive participation charges have risen dramatically – from 34% in 1950 to 58% in 2024. Pronatalist insurance policies that discourage ladies’s employment are at odds with issues a couple of diminishing variety of staff.
Analysis reveals that financial insurance policies and labor market circumstances, not demographic age buildings, play an important function in figuring out financial progress in superior economies. And with quickly altering applied sciences like automation and synthetic intelligence, it’s unclear what demand there shall be for staff sooner or later. Furthermore, immigration is a robust – and instant – software for addressing labor market wants and issues over the proportion of staff.
Total, there’s no proof for Elon Musk’s assertion that “humanity is dying.” Whereas the modifications in inhabitants construction that accompany low start charges are actual, in our view the influence of those modifications has been dramatically overstated. Sturdy investments in training and wise financial insurance policies may help international locations efficiently adapt to a brand new demographic actuality.
