Birth rates across Europe continue their long-term decline, and a fresh academic study offers a provocative explanation: the smartphone. According to Germany's Federal Statistical Office, the country's fertility rate dropped to 1.35 children per woman in 2024, two percent lower than the previous year. Provisional figures for 2025 point to around 654,300 births, a further decrease. Yet surveys show that the desire to have children remains robust. Women say they want an average of 1.76 children, men 1.74, according to the Federal Institute for Population Research (BiB).
“Having children remains a central life goal for most young people,” said Dr Carmen Friedrich of the BiB. “The current decline in births therefore does not indicate a waning commitment to family life, but rather points to births being postponed.” Among women, the so-called fertility gap—the difference between desired and actual children—has doubled to 0.41.
Smartphones and Social Shifts
A study by Nathan Hudson and Hernan Moscoso Boedo of the University of Cincinnati, highlighted by the Financial Times in May 2026, argues that smartphones have significantly accelerated the global decline in teenage pregnancies. From around 2007, when the first iPhone launched, birth rates among 15- to 19-year-olds fell sharply worldwide. The researchers analyzed data from 128 countries, including many in Europe, and found a consistent pattern: the drop in teenage fertility coincided with the mass adoption of smartphones, with timing varying by market.
In the United States, births among 15- to 19-year-olds fell 71 percent between 2007 and 2024, and among women aged 20 to 24 by 43 percent. For women in their mid-30s, rates remained stable or increased. “We find that teenage fertility has fallen fastest worldwide,” Moscoso Boedo said. The mechanism appears social rather than biological: as young people shift their interactions online, face-to-face encounters that can lead to unplanned pregnancies become less frequent.
Data from the American Time Use Survey supports this. In 2003, US teenagers spent 68 minutes a day in person with friends; by 2019, that fell to 38 minutes. Screen time for leisure rose from 22 to 96 minutes daily. To strengthen the causal link, Hudson and Moscoso Boedo examined the rollout of 4G networks in US counties. Where 4G arrived earlier, teenage birth rates fell earlier and more sharply. A parallel analysis for England and Wales, where the National Health Service provides universal contraception, showed the same pattern, ruling out policy differences alone.
The study’s main effect is on unintended teenage pregnancies. For women over 25, who account for about 80 percent of all births, no significant impact was found. So the research cannot fully explain the overall birth rate decline, but it illuminates a social mechanism: when young people spend less time together in person, the circumstances under which relationships and pregnancies form change. This feeds into a broader debate about how smartphones have reshaped social lives across Europe.
Europe’s Fertility Landscape
Germany’s trend mirrors the EU-wide picture. Eurostat reports about 3.55 million births in the EU in 2024, 3.3 percent fewer than in 2023. The average fertility rate stood at 1.34 children per woman, down from 1.38. Since 1964, when it was 2.62, the rate has nearly halved. No European country is above the replacement level of 2.1. Within the EU, rates range from 1.01 in Malta to 1.72 in Bulgaria. Among large economies, France leads with 1.61, while Spain (1.10) and Italy (1.18) lag. Even Nordic states, long seen as models for family policy, have seen sharp declines in recent years.
“Explaining cross-country differences in fertility remains difficult,” said Dr Julia Hellstrand of the University of Helsinki. “Many of the factors that once accounted for variation between states seem to have lost importance.”
Sociologist Martin Bujard of the BiB told Deutschlandfunk that Germany’s fertility rate did rise after family policy reforms around 2010, but today issues like rising housing costs and inflation have a greater impact. A separate study by the ifo Institute and Stanford University points to another lever: in households with at least one day of working from home per week, the fertility rate is 14 percent higher. “Greater flexibility through working from home could help people realise the family size they want,” said ifo researcher Mathias Dolls.
The smartphone study adds a digital dimension to a complex picture. As European policymakers grapple with demographic decline, understanding how technology reshapes social interaction—and its unintended consequences—will be crucial. For now, the evidence suggests that while smartphones are not the sole cause, they are a significant factor in the changing patterns of family formation across the continent.
