New Study Claims iPhone Helped Drive US Baby Bust

A new working paper says the iPhone may have changed more than the way Americans work, scroll and socialize — it may have helped reshape the family itself.

“We do not claim that the iPhone is the sole cause of the post-2007 decline,” researchers Caitlin K. Myers and Ezekiel Hooper wrote in a National Bureau of Economic Research working paper, “nor that no policy lever can move the trajectory.”

The paper, titled “Is the iPhone Birth Control? Causal Evidence from AT&T’s 2007–2011 Carrier Monopoly,” argues that Apple’s first modern smartphone “played a sizable role” in the drop in U.S. births between 2008 and 2011.

The study has not been peer-reviewed, and NBER says its working papers are circulated for discussion and comment. Still, the claim grabbed attention because it connects one of the most familiar devices in American life with one of the country’s thorniest family questions: Why are fewer babies being born?

The researchers focused on the iPhone’s unusual early rollout. From June 2007 until February 2011, the iPhone was available in the United States only through AT&T, which gave Myers and Hooper a way to compare counties with strong AT&T mobile broadband coverage against areas where rival carriers had a stronger footprint.

According to the paper, access to the iPhone reduced births by 4.5% to 8.0% among women ages 15 to 19 and by 3.2% to 6.6% among women ages 20 to 24. The researchers also found smaller but statistically significant declines among older age groups.

“Overall, the diffusion of the iPhone explains 33–52% of the decline in the general fertility rate among women aged 15–44,” the paper’s abstract states.

That conclusion is bold, and not everyone buys the full argument. 9to5Mac’s Ben Lovejoy noted that iPhone owners also tended to come from more educated, higher-earning demographics, groups that already showed lower birth rates, especially for unplanned pregnancies.

The authors tried to address that concern by using AT&T’s early iPhone monopoly as a natural experiment rather than simply comparing iPhone owners with everyone else. They also said placebo analyses using Verizon and Sprint coverage did not show the same pattern.

The heart of the paper is not that a rectangle of glass and metal somehow caused the baby bust by itself. The researchers argue that smartphones may have reduced in-person friendship, dating and sexual activity while increasing solitary online habits, including pornography consumption.

“National-survey evidence on time use and sexual behavior is consistent with the iPhone reducing in-person interactions, increasing pornography use, and reducing sexual frequency,” the abstract states.

For families, the study adds another layer to a conversation parents already know well. Smartphones are not morally neutral just because they fit in a pocket; they train habits, shape attention, tug people away from real-life relationships and quietly teach users what kind of life feels normal.

Movieguide® has long encouraged parents to think carefully about entertainment and technology, not out of fear, but out of stewardship. If this study is even partly right, the question is not only whether children spend too much time on screens, but whether adults have allowed screens to weaken the very relationships that make family life possible.

The iPhone did not create selfishness, loneliness or sexual brokenness. But a culture that treats constant connection as a substitute for embodied love should not be surprised when marriage, intimacy and children become easier to postpone.

The paper does not settle the debate over America’s falling birth rate. It does, however, raise a useful warning: Technology can entertain, inform and connect people, but it can also crowd out the face-to-face life that families need to flourish.
