NA = not available; organizational units providing partial responses are included in complete response column prior to 1981 and reported separately beginning in 1981.
a 1976 survey also collected 1975 data from master's-granting institutions.
b Master's-granting institutions were not surveyed in 1978; totals represent estimates based on 1977 and 1979 data.
c Calculated using response-rate formula used through 2003. See appendix A, "Technical Notes."
d Calculated using response-rate formula used from 2004 to 2006. Schools closed in 2005 because of Hurricane Katrina were counted as nonrespondents.
e Calculated using response-rate formula implemented in 2007. See appendix A, "Technical Notes."
f The 2010 and 2011 postdoc and nonfaculty researcher data were reimputed following the 2012 data collection; these numbers have been updated to reflect the reimputed data and supersede those contained in previous reports.
