I'm aware of state universities public data. The AAUP and Chronicle year appear to average across disciplines, someone in a business school will make much more than an English prof. APA doesn't list institutions just areas and also averages.
In addition, this data allows one to see what they are paying first year assistant profs. The other data averages across all years of assistant prof.
If there is a website that has first year assistant prof, in psychology, by area, by institution….that would be helpful. Otherwise, reporting on this forum works.
