Difference of professor salaries between different department in the United States Is there any research/study/survey/... that looked at the difference of professor salaries between different department in the United States?
Here's one that's readily accessible, though the full data isn't public (but can be obtained).   Here's another one in a much more concise format, though a bit older.

At least for public universities, it's not too hard to do such a survey since our salaries are public record.  I haven't actually checked but I would imagine that the groups that have done these surveys keep them updated every so many years so you can use the ones I linked to to find more.
