America’s baby bust may be linked to the iPhone, study says

The article discusses a National Bureau of Economic Research working paper arguing that the iPhone may have contributed materially to the decline in U.S. birth rates after 2007. Researchers estimate the smartphone’s diffusion explains 33% to 52% of the drop in the general fertility rate among women aged 15–44 from 2007 to 2011. The study links smartphone adoption to reduced in-person socializing, lower sexual frequency, and more access to pornography, with teen birth rates and young adult birth rates also falling. From a market perspective, the piece is more of a social-impact analysis than a direct market catalyst, but it reinforces the broad consumer-tech narrative around Apple’s ecosystem influence and the societal footprint of the iPhone.
