For the FY 2016 survey, there were substantive changes made to the field list; classification structure of R&D; and, scientific fields were renamed with some disciplines moved to different subfields. Several universities also changed the way that they report their R&D funding, which in some instances leads to large increases from FY 2015 to FY 2016. A change in reporting medical school R&D, for example, led to a 50 percent increase in R&D funding for the University of Pennsylvania during that time.
A future Digest article will explore R&D expenditures at colleges and universities by state.
