IT Worker-to-User Ratio Survey?

Breid asks: "This year has definitely been a career nightmare for IT pros. Our own company has seen our staff trimmed to near nothing and frankly, the workload is beginning to stretch people to the breaking point. With performance reviews coming up I want to make some statements to upper management concerning personnel and compensation. You can find plenty of salary surveys, but I haven't seen statements regarding the size of staff involved. And IMHO, workers on a 5 person staff supporting 200 need some compensation adjustment vs a 20 person staff supporting the same user base. At this point (for all of you still employed), what's the IT worker to workstation ratio look like? Or is anyone aware of any statistical data compiled about this?"
