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. 2007 data presented in this table are the data collected in 2007, which were labeled as "2007new" in the past publications. See appendix A in http://www.nsf.gov/statistics/nsf10307/ for more detail on the changes made in 2007.

^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.

NOTE: "Field" refers to the field of the unit that reports postdocs to the Survey of Graduate Students and Postdoctorates in Science and Engineering.
