A newly published study says the advent of the iPhone explains a 33-52% decline in U.S. birth rates for women 15-44 between 2007 and 2011.

Investigaciones revelan que la reducción de nacimientos se acentuó en zonas con acceso temprano a smartphones, especialmente entre adolescentes, con caídas del 4,5% al 8%.

The iPhone was introduced in 2007, the same year the U.S. birth rate started to slide. The issues could be linked, a new analysis finds.
