4G and smartphones blamed for global birth rate decline

Global birth rates are plummeting faster and wider than predicted. In over two-thirds of the world’s 195 countries, the average number of children born per woman has fallen below the ‘replacement rate’ of 2.1. This threshold is required to maintain a stable population without relying on immigration. In 66 countries, the average number of children per woman now hovers closer to one than two, with some nations recording zero births as the most common outcome. Researchers have identified smartphones and digital technology as primary culprits, based on analysis of population records and Google search data. Birth rate decline is no longer confined to wealthy nations, with many developing countries now exhibiting lower fertility rates than far richer nations. In 2023, Mexico’s birth rate fell below that of the United States for the first time, with similar trends emerging in Brazil, Tunisia, Iran, and Sri Lanka. This phenomenon poses new global threats, as population decline forces low- and middle-income countries to age before achieving prosperity. Research by Nathan Hudson and Hernan Moscoso-Boedo at the University of Cincinnati highlighted the impact of 4G network launches on birth rates in the US and UK, with declines earliest and most rapid in regions with early high-speed internet access. The turning point for birth rate declines globally coincided with mass smartphone adoption in local markets, with sharp drops beginning in the US, UK, and Australia from 2007. Similar declines emerged in France and Poland around 2009, while Mexico, Morocco, and Indonesia saw drastic falls around 2012. Advanced gadgets are believed to have radically altered youth behaviour, drastically reducing face-to-face socialisation and undermining fertility rates.
