There is and you don't have to pay for it. The Creative Group is a division of Robert Half, a staffing/recruiting company which also does technical staff. I found the information (particularly the bit about local variances) very valuable. Any hiring manager can reach out to one of their recruiters/account managers and get a copy of this thing. The downside is you have to interact with a recruiting company. :-) It would be great if someone posted the PDF version of the document like they did this one.
