NOTES: SDR is a sample survey; SED is a census. Start year and End year are defined as the earliest and latest recorded use of a field in the 2015 Doctorate Records File, respectively. Field of study reporting for the 2017 SDR is updated to better align with the National Center for Science and Engineering Statistics' Taxonomy of Disciplines (ToD), which is based on the Classification of Instructional Programs (CIP 2010) issued by the National Center for Education Statistics. This crosswalk displays the traditional field of study aggregations. The 2017 survey results include both traditional field of study aggregations as well as new ones based on the ToD.
