Looking at most of that data, a lot of this seems to be a combination of a tanking economy/jobs market/gig economy, and a technology that allows one to feel more connected without having to spend money to go out. The iPhone has worn the continuing echoes of late stage capitalism like a glove, and in the same way the homeless use drugs to make their shitty lives more bearable, it seems to me people are doing the same with phones. You can sleep anywhere if you're drunk, and you don't have to spend money by going out (goods and transport) if you have your phone/and/or services that popped up to support the interwebs 2.0.
