iPhone's debut crushed young women's fertility, new study says

The first iPhone served as a technological marvel for some, but may have acted as birth control for a significant segment of the female population.A working paper, published in the National Bureau of Economic Research, discussed a causal relationship between the release of the original iPhone in 2007 and a declining general fertility rate in the United States.'The algorithms ... are incredible at getting you to keep scrolling.'While women of all age groups shelled out 499 for the Apple smartphone, women under 25 years old seemed significantly hit by its introduction, according to researchers Caitlin K. Myers and Ezekiel Hooper.The 22 drop in fertility rate in the U.S. since 2007 is not explained by the economy, contraceptives, housing, or child care costs, the researchers wrote. Instead, the study looks at causal evidence that coincides with the release of the iPhone, combined with other known factors like time use and sexual activity.The study surmised that access to the iPhone reduced births by 4.5-8.0 among those ages 15-19, as well as between 3.2-6.6 for those 20-24.There were also statistically significant but smaller declines among older age groups, the study claimed.RELATED: Can we have online safety without total surveillance?
