Graduate Students and Postdoctorates in Science and Engineering: Fall 2011


General Notes


Data presented here are from the annual National Science Foundation–National Institutes of Health Survey of Graduate Students and Postdoctorates in Science and Engineering (GSS). Unless otherwise specified, data published here represent estimates of total graduate enrollment as of fall 2011 in science, engineering, and selected health fields in 13,785 graduate units (departments, research centers, degree-granting programs, and affiliate health facilities) at 565 academic institutions in the United States and outlying areas.

The survey was refined in 2007 to improve reporting: new fields were added and some fields were reclassified. Because of these changes, the 2007 data are presented two ways in multiyear tables:

  • "2007new" shows the data as they were collected using the new methodology.
  • "2007old" shows the data as they would have been collected in prior years.

The 2008–2011 data are comparable with "2007new" data.

Beginning in 2008, the tables that provide data by institution no longer list names of the nonresponding institutions, although their data are imputed and are included in the totals for all institutions.

In 2011, the GSS code list was updated to the Classification of Instructional Programs (CIP) 2010, which all institutions were required to use beginning with the 2010–11 reporting to the Integrated Postsecondary Education Data System (IPEDS). A total of 58 new 2010 CIP code titles were mapped to the GSS codes, 14 CIP code titles were moved between GSS codes, and 24 CIP code titles were removed as ineligible fields. Although the GSS code list update affected 28 of the 84 GSS codes, impact was typically small and did not change the overall trend data from 2010 to 2011 GSS.

Collection of these graduate enrollment and postdoc data began in 1966, and the survey has been modified periodically since then. Appendix A, "Technical Notes," provides more detailed information on the survey over the years. The latest data for prior years are published in this report; only these data should be used in historical analyses.

Data from GSS are available at http://www.nsf.gov/statistics/gradpostdoc/. Selected data from the survey are also included in the Academic Institution Profiles series (http://ncsesdata.nsf.gov/profiles/). Data from the GSS fall 1972 through fall 2011 are also available in public-use files and from the WebCASPAR system at http://ncsesdata.nsf.gov/webcaspar/.
