It's very hard to get real data, so I can't really fault you for the lack of a good cite. However, it's not like the companies claiming a shortage are exactly forthcoming with the data themselves.

I find it remarkable that people make claims of shortages without sharing information about the skill set they need and the compensation they're offering. Well, I don't find it remarkable, in the sense that I don't find PR-speak especially surprising anymore. I guess I should say I find it galling.
