Researchers are pointing to a perhaps unexpected factor behind the trend of people having fewer children: the smartphone. A new report suggests that the devices now central to daily life may be playing a measurable role in declining birth rates. The claim adds a modern, technological dimension to a long running demographic question. It also frames the smartphone not merely as a communication tool but as a possible influence on family formation.
According to the report, smartphones could account for more than 30 percent of the decline in the fertility rate among women between the ages of 15 and 44. That figure places phones among the more significant contributors researchers have tried to quantify. The report does not claim phones are the sole cause, but it points to them as a substantial part of the picture. The estimate is what has drawn particular attention to the findings.
The working theory behind the report centers on how smartphones may be changing human behavior. Researchers suggest that people are spending less time socializing in person than they once did. They also point to a pattern of people dating later in life. In addition, the report describes people having less intercourse and forming fewer long term relationships.
To anchor the trend in data, the report draws on figures from the Centers for Disease Control and Prevention. The CDC has reported a 23 percent drop in the fertility rate since it reached a peak in 2007. That year is significant to the researchers' argument for a specific reason. It was the same year that Apple released the iPhone, marking the arrival of the modern smartphone era.
The timing alone is not the only basis for the comparison. In the early years of the iPhone, AT&T held the exclusive contract to carry the device. Researchers used that detail to design their analysis. They compared fertility rates in areas that had widespread AT&T coverage with counties that had little or none.
The researchers describe what they observed as smartphones became common across the country. Time spent with friends fell sharply over that period. Sexual activity also declined notably during the same stretch of time. At the same time, consumption of pornography rose, which the report frames as a possible substitute for a sexual partner.
Even so, the report does not present smartphones as the only explanation for the decline. Experts say other factors must be taken into account when interpreting the numbers. Among them is greater access to contraception. Economic reasons, including the cost of childcare, are also cited as important considerations in why people are having fewer children.
