Two U.S. studies examine whether smartphone adoption contributed to falling birth rates
The Facts
- Two recent U.S. studies examined whether smartphone adoption contributed to declining birth rates, including one paper published Monday and another released in May.
- Multiple reports say U.S. fertility rates have fallen by about 22% since 2007.
- One study by Middlebury researchers used the fact that, until 2011, iPhones in the United States were available only through AT&T to compare counties with stronger and weaker access.
- That county-level analysis found larger declines in births among younger women, including ages 15 to 19 and 20 to 24, in places with greater iPhone access.
- The studies suggest smartphone use may have reduced in-person social interaction and sexual activity, which researchers present as one possible pathway linking phones to lower birth rates.
- The research matters because governments in many countries are trying to understand and respond to falling birth rates, and the studies add smartphones to a list of possible contributing factors alongside economic conditions and access to contraception.
- The studies do not conclude that smartphones were the only cause of lower birth rates, and reports note that other explanations such as the 2008 recession, housing and child-care costs, and birth control access remain part of the debate.
How left and right are reading this
- Both agree
- Smartphones may be one contributor to falling birth rates, but the studies do not treat them as a standalone explanation and keep economic conditions, housing and child-care costs, and contraception in the picture governments must weigh.
- They split on
- Less a disagreement than a question of emphasis: a major social shift affecting younger women and widening the fertility debate, versus a caution against forcing the evidence into any single-cause explanation.
Context
How did researchers try to test the smartphone hypothesis?
One study took advantage of the fact that iPhones were sold only through AT&T in the U.S. until 2011, allowing researchers to compare counties with near-universal AT&T coverage to counties with little or no coverage during that period NZ Herald,Excélsior,rts.ch,CRHoy.com | Periodi….
Which groups appeared most affected in the study findings?
Reports on the county-level study say the largest birth declines linked to iPhone access were among younger people, especially ages 15-19 and 20-24, with smaller but still statistically significant declines among older women NZ Herald,Le Telegramme,CRHoy.com | Periodi….
Do the studies say smartphones fully explain the drop in births?
No. Coverage of the research says the authors did not present smartphones as the sole cause of falling birth rates, and other explanations such as recession effects, housing and child-care costs, and contraception remain under discussion Axios,NZ Herald,Straits Times.
