For many of these agencies, the major form of graduate student support is indirect, through research assistantships, rather than through direct fellowships or traineeships.
Several agencies concentrate much of their funding in one field.
NIH spends 89 percent of its funds on the life sciences. In your request, include the NSF publication number and title, your name, and a complete mailing address. It focuses on these agencies because they are the only ones identified individually in the 1997 Survey of Graduate Students and Postdoctorates in Science and Engineering , which is the source of the graduate student support data cited here. It provides 98 percent of HHS's total academic research funding and its life sciences academic research funding. Another agency, not included in this analysis, that concentrates its academic research funding is DOE, which allocates 60 percent of it to the physical sciences.
