For more than a decade, falling birth rates and delayed marriage have been explained the same way: young people, the story goes, have simply stopped wanting the things previous generations wanted. They prioritise careers over commitment, freedom over family, self-actualisation over settling down. It is a tidy narrative, repeated in boardrooms, government white papers and opinion columns alike. It is also, according to the largest global survey of its kind, wrong.

The United Nations Population Fund's Lives, Choices and Futures , published this month, surveyed 108,926 internet-connected adults aged 18 to 39 across 73 countries — the most geographically diverse dataset ever assembled on this question. Two numbers from it deserve to end the “they don’t want it” narrative for good:

  • MARRIAGE: Among 25-to-39-year-olds currently dating but not yet living with a partner, 84% say they want to marry or move in with that partner.
  • AND KIDS: And two children remains the most commonly cited ideal family size across five of seven world regions and every income bracket the survey measured, from 32% of respondents in lower-income countries to 45% in high-income ones.

The aspiration has not shrunk. What has been lost is the confidence that it’s achievable — and that distinction changes who is responsible for fixing it. Earlier reports point to a mix of cultural, economic and social forces.

The UNFPA report, authored by a team led by Priscilla Idele of UNFPA alongside Arnstein Aassve of Bocconi University and colleagues, is explicit about what it found and what it didn't. “The question is not whether young people value these life goals,” writes Diene Keita, UNFPA's Executive Director, “but whether they have the conditions to realize them.” The data backs her up at every turn.

Financial security is the top consideration for entering a partnership, important for 81% of respondents, rising to 88% as a precondition for parenthood. Stable employment (87%) and emotional readiness (85%) follow close behind. Meanwhile, economic and housing constraints are the single most commonly reported barrier to forming a partnership at all, cited by 57% of respondents — ahead of every relational or personal factor the survey tested.

Perhaps the most striking finding sits in the data on people running out of biological time to decide. Among 35-to-39-year-olds without children in Western Europe, Australia, Canada and the United States — the demographic most often cited as evidence that an entire generation opted out of parenthood — 73% of men and 62% of women say they would still ideally like to have children. That is not a generation that changed its values. It is a generation waiting for the conditions to live them.

Why No Babies? The Key Question, Badly Answered

This distinction is not academic. It determines where responsibility — and opportunity — sits. If falling marriage and birth rates reflected a genuine values shift, then there is little for employers, policymakers or institutions to do beyond adjusting to a smaller, later-forming workforce, a shrinking family-oriented consumer base and ageing populations. If instead they reflect a gap between aspiration and access, the responsibility moves squarely onto the institutions that control the conditions in question: pay, job security, housing affordability, parental leave and access to childcare.

UNFPA's evidence points firmly toward the second explanation. The report's authors are careful to note the data is not nationally representative — it draws from internet-connected respondents and should be read as directional rather than a precise population estimate — but the pattern holds with remarkable consistency across regions, income levels and age groups. This is not noise. It is a signal, and it is aimed directly at employers who have spent the last decade treating declining marriage and birth rates as a demographic inevitability rather than a design failure.

Where Governments Have Tried — And Mostly Failed

Governments have not been passive on fertility. Many, particularly conservative-leaning administrations anxious about demographic decline, have spent the past decade trying to reverse falling birth rates directly, through cash bonuses, tax breaks and rhetoric about family values. Hungary has committed close to 5% of GDP to childbearing incentives; the result has been a modest rise to a fertility rate of 1.6, still well below replacement. Most such programs, researchers have found, mainly shift the timing of births that would have happened anyway rather than creating additional ones.

The United States illustrates the gap between rhetoric and investment very clearly. In April 2025, the Trump administration floated a $5,000 cash “baby bonus” for new mothers, with the president saying it “sounds like a good idea to me.” That direct payment was never enacted. What became law instead was a $1,000 government-seeded “Trump account,” for children born between 2025 and 2028, into which parents may voluntarily contribute up to $5,000 a year of their own money. The government's actual outlay is $1,000 — a fifth of the figure that made headlines — layered onto an economy where the average cost of raising a child now exceeds $297,000 and the fertility rate sits at 1.6, near a record low. Critics on both sides of the aisle have made the same point: a headline-grabbing savings account does little against the structural costs — childcare, housing, paid leave — that UNFPA's own respondents rate as the actual preconditions for parenthood.

South Korea is the exception, and the reason is instructive. Facing the world's lowest fertility rate, the government has committed close to $300 billion to family policy since 2006 and now backs new parents with a national monthly stipend, birth grants, and, in some regions, housing and cash benefits that combine to well over $50,000 per child.

The effort appears to be working: South Korean births rose for fifteen consecutive months through September 2025 , up 6.9% year-over-year in the first three quarters of the year — the sharpest increase since 2007. Analysts caution that some of the rebound reflects a temporary bulge of women born in the 1990s reaching their thirties, and that South Korea's roughly $275,000 average cost of raising a child still looms over the numbers. But the direction matches the UNFPA data precisely: the one government that has put serious money behind the specific preconditions young people say they need — financial security, housing, direct cost relief — is also the one seeing results. Rhetoric about family values, without matching investment, has not moved the needle anywhere else.

You Get What You Design For

A handful of organizations have begun treating employment stability and family support as retention and talent-acquisition strategy. Vodafone's global parental leave policy , rolled out across more than two dozen markets, offered 16 weeks of fully paid leave to all parents regardless of gender, plus a phased return at full pay — a direct response to the “stable employment” and “financial security” preconditions that UNFPA's respondents rate most highly. Hewlett Packard went further still, offering 26 weeks of paid leave for new parents of either sex. These are not charitable gestures. Vodafone's own research, published in Lost Connections , found measurable costs to businesses that fail to support parents and caregivers adequately — a direct line from policy design to talent retention.

The employment-stability half of the equation deserves equal attention, since it ranks nearly as high as financial security in UNFPA's data. Unilever's U-Work model — described internally as “a contract, but not a job” — was built to give people flexible, secure income between full-time roles, addressing precisely the kind of employment precarity that the UNFPA data identifies as a barrier to major life decisions. Programs like these treat career stability as infrastructure for the personal decisions employees are trying to make, rather than as a separate HR initiative disconnected from those decisions.

The Business Case Nobody Has Made Yet

The organizations best positioned to benefit from this data are not the ones with the most generous parental leave policies in isolation — they are the ones that connect financial security, employment stability and family support into a single, coherent signal to current and prospective employees. That signal matters on the talent side because the workforce entering its prime family-formation years over the next decade is, by UNFPA's own data, not disengaged from commitment; it is waiting for the conditions.

It matters just as much on the consumer side. Any business — from housing developers to financial services firms to childcare providers — that has priced the 18-to-39 cohort out of its growth strategy on the assumption of disinterest is mispricing a market that has not disappeared. It has been waiting.

The long-standing explanation for falling birth rates and marriage rates told business leaders there was nothing to be done: young people simply wanted something different. UNFPA’s data says otherwise, with numbers precise enough to act on. Eighty-four percent still want a partner. Two children is still the dream. Who will support it?

The obstacle was never appetite. It was always conditions — and conditions are something organisations, unlike generational character, can change.
