Two American studies by demographers suggest that the widespread use of smartphones is linked to a decline in fertility rates in the U.S. [3].
This connection highlights a potential shift in human behavior and social interaction. As digital engagement increases, researchers are examining how the displacement of face-to-face interaction impacts biological reproduction and population growth.
The research focuses on the period following the introduction of the iPhone in 2007. Some data suggests that the arrival of these devices between 2007 and 2011 may explain between 33% and 52% [1] of the decline in the U.S. fertility rate observed during that timeframe.
Overall, the U.S. fertility rate has dropped by 22% since 2007 [2]. This trend is particularly pronounced among young adults aged 15 to 24 [2]. While the primary focus of these studies is the U.S., some reports indicate that data from 128 countries has been examined to understand the global scale of this phenomenon [5].
Researchers said the intensive use of smartphones may foster social isolation. This isolation is thought to reduce the frequency of sexual intercourse, which subsequently lowers the number of births [6].
However, the interpretation of these findings varies among analysts. Some experts said the link between smartphones and birth rates is a measurable effect [7]. Other critics said that blaming smartphones is a simplified explanation and an "easy culprit" for a complex demographic shift [8].
Beyond the U.S., demographic projections show similar concerns in other nations. In France, projections from the INSEE suggest the population could decrease by more than three million inhabitants by 2070 [4].

The findings suggest a correlation between the digital revolution and a biological decline in reproduction. If the displacement of physical intimacy by screen time is a primary driver of falling birth rates, governments may face long-term economic challenges due to aging populations and a shrinking workforce, regardless of traditional pro-natalist policies.
