Birthrates are falling in the rich world and this leaves us with an unsolved puzzle. Women who want children are not having them. Why? Surveys tell us that, on average, women and men in rich countries would ideally like two children — near the coveted “population replacement rate” of 2.1 — but birthrates are falling far short of this. Women have more money and choices than ever, but are for some reason not able to have as many children as they would like. Why not?
Well, in places such as the UK, falling birthrates are frequently blamed on childcare, housing and income problems. In some respects, people in their 20s, 30s and 40s are worse off than their boomer parents. Hence, fewer children.
That feels right. However, compare the situation of today’s young to almost any group other than their boomer parents and our theory falls apart. Millennials in the modern rich world live in far greater luxury than their child-popping contemporaries in poorer countries. Even within millennial groups in the US and Europe, it is among the middle and upper classes where birthrates are mostly falling.

This is not just about money. Since the 1990s, parental incentives have soared across rich countries, yet birthrates have continued to plummet. A plea from a Chinese health official for leaders to “make bold innovations” to boost the birthrate, after financial incentives failed to work, fit a global pattern.
OK: So, it is about social structures, then? Lack of childcare, unequal parental leave and career penalties for mothers. Not so — or not primarily. In our fecund recent past, remember, career penalties for mothers were even higher. Mothers still suffer a career penalty almost everywhere, but attempting to remove it does not seem to alter their decisions that much.
Since 2008, amid unequalled progress in gender equality and some of the most generous parental support schemes on the planet, birthrates in Sweden, Norway and Iceland have fallen precipitously. Nordic countries are, comparatively, parental utopias, yet birthrates tick along slightly above the EU average and are still well below the replacement rate.
Better childcare and parental provision are, of course, worthwhile policies on their own terms: They increase human happiness, but they do not change birthrates all that much.
In fact, falling birthrates track with just one metric: a rise in female empowerment itself. The right to contraception and abortion allows women not to have children they do not want and life offers them a greater range of interesting choices outside motherhood.
That accounts for a lot, but it does not explain why women with all these increased choices are having fewer children than they would like. No one has nailed down the answer. What is that?
Well, here is a suggestion. Surveys of childless women tell us that a top reason is not career, lifestyle or financially related: It is that they just have not found the right partner.
This was the second-most common reason given in a representative UK study of 42-year-old childless women — right behind not wanting children. (Focusing on career was way down the list.) US studies echo this.
Fertility rates within marriages have been fairly steady since the 1990s. Gay couples have started to add to birthrates, too, but the dramatic rise in childless women — and their inability to find the right partner — is driving a good deal of the fall in the rich world’s birthrate.
Hang on, why is it that only modern women have this problem? How is this related to empowerment? Well, “just not being able to find the right man” is a fairly recent luxury for women. Their grandmothers and great-grandmothers who did not find the right man would probably at some point simply have had to pair up with the wrong man — single life, or “spinsterhood,” was just too miserable and poverty-stricken.
Women spending this Valentine’s Day alone should consider that in ages past they would probably have been married by now, happily or not.
Women may not in theory want to be single and childless, but they can afford to be if the right person does not come along. That is how increased choice might paradoxically result in women who want children not having them.
If correct, our theory would present policymakers with a conundrum. Falling birthrates are a problem for countries that fret about shrinking workforces.
However, they are also being driven by something positive: greater female choice. We cannot simply suggest single women — or indeed single men, who are making many of these choices — alter their expectations when they have freely decided that they would rather pay the price for not doing so.
Immigration is only a sticking plaster for rich countries: Birthrates will soon fall everywhere. However, there is another more radical solution to all this. Single women might not want to pair up, but they can still have children alone.
Yet single motherhood is still offputtingly tough and to some extent socially penalized. In China, single mothers have only just got the same rights as married ones. Policymakers would do well to think about how they could better support single mothers. Target them and watch birthrates rise.

A foreign colleague of mine asked me recently, “What is a safe distance from potential People’s Liberation Army (PLA) Rocket Force’s (PLARF) Taiwan targets?” This article will answer this question and help people living in Taiwan have a deeper understanding of the threat. Why is it important to understand PLA/PLARF targeting strategy? According to RAND analysis, the PLA’s “systems destruction warfare” focuses on crippling an adversary’s operational system by targeting its networks, especially leadership, command and control (C2) nodes, sensors, and information hubs. Admiral Samuel Paparo, commander of US Indo-Pacific Command, noted in his 15 May 2025 Sedona Forum keynote speech that, as
Chinese Nationalist Party (KMT) Chairman Eric Chu (朱立倫) last week announced that the KMT was launching “Operation Patriot” in response to an unprecedented massive campaign to recall 31 KMT legislators. However, his action has also raised questions and doubts: Are these so-called “patriots” pledging allegiance to the country or to the party? While all KMT-proposed campaigns to recall Democratic Progressive Party (DPP) lawmakers have failed, and a growing number of local KMT chapter personnel have been indicted for allegedly forging petition signatures, media reports said that at least 26 recall motions against KMT legislators have passed the second signature threshold
The Central Election Commission (CEC) on Friday announced that recall motions targeting 24 Chinese Nationalist Party (KMT) lawmakers and Hsinchu Mayor Ann Kao (高虹安) have been approved, and that a recall vote would take place on July 26. Of the recall motions against 35 KMT legislators, 31 were reviewed by the CEC after they exceeded the second-phase signature thresholds. Twenty-four were approved, five were asked to submit additional signatures to make up for invalid ones and two are still being reviewed. The mass recall vote targeting so many lawmakers at once is unprecedented in Taiwan’s political history. If the KMT loses more
In a world increasingly defined by unpredictability, two actors stand out as islands of stability: Europe and Taiwan. One, a sprawling union of democracies, but under immense pressure, grappling with a geopolitical reality it was not originally designed for. The other, a vibrant, resilient democracy thriving as a technological global leader, but living under a growing existential threat. In response to rising uncertainties, they are both seeking resilience and learning to better position themselves. It is now time they recognize each other not just as partners of convenience, but as strategic and indispensable lifelines. The US, long seen as the anchor
