Oh no, that 23% has nothing to do with unemployment, or okay, in part because of that. But the fun aspect is that the question of what exactly the "poverty line" is jumps all over the place. it's used as such a variable definition these days. It doesn't mean "can't afford rent or food" it can be what other countries might view as luxuries as well.
I mentioned it more as one of those quirky, somewhat interesting data points. And for that interesting mix of "If it wasn't for the government it would be higher" contrasted to "if it wasn't for the government it would be lower"...
