To determine the levels of interdisciplinary work among new doctoral recipients, staff at NORC at the University of Chicago drew on two items in the Survey of Earned Doctorates (SED). The first of these asked each new PhD to “choose the code that best describes the primary field of your dissertation.” The second item asked, “If your dissertation was interdisciplinary, list the name . . . of your secondary field.” (For a complete list of the field and discipline response options, see pages 6 and 7 of the 2012–2013 SED questionnaire).
