Today's chart comes via Allison Schrager, and plots the riskiness of an economy (judged by the price of CDS coverage for its bonds) vs. the number of men aged 25-34 who are still living with their parents. The correlation is pretty striking:
It's possible, of course, that this is actually demonstrating some underlying correlation that has nothing to do with how many men live at home into their 30s. Still! It's interesting. And amenable to absolute mountains of amateur sociology. So go to it, blogosphere.
