Up here in a rural northern location it is easy to see a marked increase (from zero previously actually) of younger folks lingering about, sitting on motorbikes, not doing anything but talk and stare at mobiles. Every day I'm out (and that is only a couple of times a week now) I see groups in the same places and recognize many by the bikes and clothes. They weren't there last year. Everyone has family members returned from Bangkok and surrounds with next to nothing and surviving on family help and a little casual farm work. Extrapolating what I see here tells me the figure is already well into the millions. And petty crime is increasing.
