alt Hacker NewsThey compared AT&T users with an iPhone (the only place you could get an iPhone) to users with other carriers.
Since people using other carriers also experienced 2008, it's not that.

Or, the kind of people who bought iPhones in 2008 were a different subset of the population than those who didn’t and as such they have different opinions and preferences when it comes to family and kids?
With that said, I can also see that infinite entertainment and infinite information makes you deprioritize having children.
But it’s far from proof, this study. It’s more like “I found some numbers that support my already existing opinion, so let’s run with that”.
Ah but maybe having an iPhone causes you to be more exposed to financial crashes.
Or maybe the type of person that buys iPhones also spends too much on other items causing them to be over leveraged when a financial crash does occur.
Even if you control for age and wealth, the people who used iPhones in 2008, i.e. tech hipsters, are obviously different in tangible ways from the people who didn't use iPhones in 2008. It's not possible to prove causality from that.
