Smartphones arrived just before the US fertility rate plunged. One study says it’s a direct cause

Key Points:

• A new study suggests that the introduction and spread of smartphones, particularly the iPhone starting in 2007, significantly contributed to the decline in US fertility rates between 2007 and 2011, especially among teens and women in their 20s and 30s.
• Researchers theorize that smartphones may reduce physical social interactions and sexual activity by substituting in-person contact with online interactions, potentially leading to fewer unintended pregnancies.
• Some experts caution that the decline in fertility is a long-term trend influenced by multiple factors such as economic conditions, changing social norms, housing costs, education, and contraception access, making it difficult to attribute the decline primarily to smartphones.
• The study acknowledges that smartphones are not the sole cause of declining fertility and highlights the complexity of policy responses, suggesting that fostering face-to-face human interaction might be more effective than financial incentives in addressing fertility declines.
• Critics also note that the period studied predates widespread use of many smartphone features like social media and dating apps, and that broader historical and technological contexts must be considered when interpreting fertility trends.
