There's some evidence that mobile phone access is one of the biggest drivers in this. This talks about teen fertility but I'd imagine it's similar in other age categories as well.

Interesting. Once you have a cellphone to amuse yourself, perpetuating the species is just too much bother?

Phone + PC/TV probably takes an hour or two of people their day on average. If they didn't have access to it I assume they'd be meeting up with other people out of boredom and that'd lead to sex, doesn't seem too strange.

		I suspect on average it's much higher than an hour or two.

Or you spend all your time on your phone and can't understand why you're just not getting ahead in life.
