There has been much discussion of the percentages of faculty salaries coming from internal versus external sources. In the context of helping prepare a recent paper from leaders of academic medical centers, I was able to obtain some data from the AAMC (American Association of Medical Colleges) regarding the distribution of levels of extramural support across 72 academic medical centers for 2013. These data are shown below:
These data were collected under terms of strict anonymity for institutions. Furthermore, as noted in the caption, they were collected by obtaining the total amount of extramural support going to faculty salaries and dividing by the total amount going to salaries for individuals with at least some extramural support. Thus, distributions of levels of support across a given institution are not available. Nonetheless, these distributions provide some sense of the range of individual institutional behavior that is more informative than an overall median with no other information.
