In Milan, a 38-year-old woman no longer talks about the second bedroom. She and her partner, both university-educated and employed, once planned two children. But a decade of short-term contracts and a rental market that devours half their income have eroded that vision. “They would have wanted almost two children each, and they have not had even one,” explains Letizia Mencarini, a demographer at Bocconi University who co-authored a survey of 108,000 people aged 18 to 39 across 73 countries. The woman’s story is a statistical unit in that study, one of millions who have postponed — and perhaps abandoned — parenthood because the material scaffolding never materialised.

Viewed from Buenos Aires, the same gap yawns wide, though it wears different bureaucratic clothing. Official unemployment stands at 7.8 per cent, a figure that would once have signalled good health. Yet researchers at the Argentine Social Debt Observatory, poring over fifteen years of household survey data, found that the adjustment did not come through job losses alone but through a quiet transformation of what work means. The micro-informal sector — casual labour, unregistered self-employment, off-the-books salaried work — swelled from 46 per cent to 48 per cent of all employment between 2010 and 2025. Even within the formal private sector, precarious conditions grew. As a result, a worker in a regulated, registered job is eighteen times more likely to land in the highest income bracket than an informal counterpart, for whom the odds of advancement are practically nil. In the industrial corridors of Greater Buenos Aires, where one in four of the nation’s lost registered jobs has vanished since late 2023, the family starts that demographers once took for granted are increasingly elusive.

Tehran offers the most extreme version of this selective blindness. The official unemployment rate of 7.5 per cent is a number maintained by a simple rule: anyone who has stopped actively seeking work — after years of rejection — is removed from the tally. Out of 66 million working-age Iranians, only 26 million are counted as economically active. Among women, the silence is overwhelming: just twelve in every hundred of working age are employed, against a global average of fifty. The war that flared with Israel and the United States has, by the labour ministry’s own estimate, destroyed over a million jobs, while economists close to the market put the true number of newly unemployed at three to four and a half million. Analysts in London calculate that a realistic unemployment rate could reach 25 per cent by year’s end.

And yet, demographic anxiety itself deserves a second look. Research led by Nobel laureate Daron Acemoglu, examining long-run fertility declines across continents, found that every point drop in the birth rate since 1950 corresponded with a 26.8 per cent rise in GDP per worker. Firms and workers, when confronted with a shrinking labour supply, choose technology — an automation dividend that so far has kept productivity growing even as cradles empty. In Argentina, seven out of ten older workers say they intend to keep working past retirement, driven partly by necessity and partly, the surveys suggest, by an identity fused with labour.

What remains is a landscape of paradox. The oil wells of Vaca Muerta pump record volumes, and grain mills run at full capacity, while textile factories and auto plants shed workers. In a Milan neighbourhood, a spare room that was to have been painted yellow remains a study, its door closed. The child that was desired but never conceived is not an isolated sorrow; it is the silent counterpart to every upbeat headline about a labour force adapting itself to a thinner world.
