na = not applicable; data were not collected at this level of detail. ne = not eligible; data were not collected for this field prior to 2007.
nec = not elsewhere classified.
a In 2007, eligible fields were reclassified, newly eligible fields were added, and the survey was redesigned to improve coverage and coding of eligible units. “2007new” presents data as collected in 2007; “2007old” shows data as they would have been collected in prior years. The science fields Communication and Family and consumer sciences and human sciences were newly eligible in 2007; data for these two fields begin in 2007new. The science field Multidisciplinary and interdisciplinary studies was also added to the code list in 2007; some data reported in this field were reported under other fields before 2007 and are included in those fields in 2007old. Neuroscience is reported as a separate field of science in 2007new; data were reported under health field Neurology in 2007old and previous years. Architecture is reported as a separate field of engineering in 2007new; data were reported under Civil engineering in 2007old and previous years. See appendix A in http://www.nsf.gov/statistics/nsf10307/ for more detail.
b In 2010, the postdoc section of the survey was expanded, and significant effort was made to ensure that appropriate personnel were providing postdoc data (see appendix A for more information). Thus, it is unclear how much of the increases in 2010 and later years over 2009 and prior years are from growth in postdoctoral appointments and how much are from improved data collection. More information on the changes to the postdoc data collection is available at http://www.nsf.gov/statistics/infbrief/nsf13334/.
c Postdoc data from 2010 and 2011 were reimputed following the 2012 data collection; these data supersede those contained in previous reports.
NOTES: “Field” refers to the field of the unit that reports postdocs to the GSS.
