I think this is very important, basically that if you look at the data by something like market cap it would probably skew very young. E.g. AirBnB and Dropbox are (IIRC, may have changed by now) the majority of total valuation for ycom, and those companies were both started by early 20-somethings.

YC itself skews young, at least in part I'd say because the sort of help it provides is something that is more needed the younger you are. It's vanishingly unlikely that I will need YC's money, connections, or imprimatur for a startup at this stage in my life. When I was 24 starting a company, it would have been hugely helpful.
