In 2007, Apple CEO Steve Jobs introduced the iPhone, a device that would change how the world communicates. A recent working paper presents a compelling argument that smartphones have played a significant role in the continuous decline of birth rates over the past two decades.
Research led by economist Caitlin Myers offers insight into why fewer women are having children. The U.S. has seen a 22% drop in birth rates since 2007. Initially, economists believed the Great Recession was responsible, expecting birth rates to bounce back as the economy recovered. Yet, even after economic improvement, birth rates continued to decline. So, if the recession didn’t cause the decrease, what did?
It must be significant, and it needs to align with around 2007 since that’s when the decline began.
Myers proposes that the widespread introduction of smartphones, starting with the iPhone, could explain a substantial portion of this decline.
The iPhone’s Initial Market Impact
Myers’ hypothesis is grounded in a natural experiment arising from the early smartphone market. Initially, iPhones were exclusive to AT&T. In areas with AT&T coverage, iPhones were accessible, while in places like Vermont, they were not.
Birth rates dropped more significantly in regions where people could easily access iPhones. This pattern persisted even when adjusting for factors such as population density and local economics.
Shifting Social Interactions
The most substantial birth rate declines occurred among teenagers. Jean Twenge, a psychology professor at San Diego State University, notes that smartphones reshaped adolescent behaviors. Young people began spending more time online and less in face-to-face interactions.
Myers contends that this change in interaction patterns likely contributed to fewer pregnancies, as conventional sexual interactions decreased among teenagers.
Access to Information and Alternatives
Smartphones have also facilitated access to information on contraception and abortion, potentially influencing birth rates. These devices have made it easier to access pornography, which, according to Myers’ students, serves as a substitute for physical relationships.
While Apple declined to comment on Myers’ research, the rise of alternative smartphones across different networks has made such devices commonplace. This raises questions about whether birth rates will stabilize or keep declining in the coming years.
Myers believes the influence of smartphones on behavior and fertility patterns could persist, necessitating continued observation to understand long-term trends.
