A = subfields within this GSS code changed between 2016 and 2017. B = GSS code moved broad field. C = subfields remain eligible, but the 2016 GSS code is no longer used. D = new GSS code in 2017 consisting of previously eligible subfields. E = some 2016 subfields became ineligible in 2017. F = code no longer includes graduate students. G = deleted code; subfields no longer eligible. na = not applicable; no GSS code label in this year.
GSS = Survey of Graduate Students and Postdoctorates in Science and Engineering; nec = not elsewhere classified.
NOTES: In 2016, some codes were combined for public-use reporting: 115 biological and biosystems engineering was reported under 102 agricultural engineering; 116 nanotechnology was reported in 980 multidisciplinary and interdisciplinary studies; 205 materials science was reported as part of 110 metallurgical and materials engineering; 911 criminal justice - safety studies was included under 910 social sciences nec; 912 international relations and national security studies, 913 public administration, and 914 public policy analysis were combined under 907 political science and government.
