NOTE: Field groupings may differ from those in reports published by federal sponsors of the Survey of Earned Doctorates. See inside the back cover for a description of fields as reported in this table. Physical Sciences includes Mathematics and Computer Sciences, as well as Physics/Astronomy, Chemistry, and Earth/Atmospheric/Marine Sciences. Refer also to the explanatory note about this table in front of Appendix A .
*Includes 2-year, 4-year, and foreign colleges and universities, medical schools, and elementary/secondary schools,
†Includes only recipients with definite employment plans. Revisions to the survey form in 1990 appear to have resulted in a higher rate of nonresponse to the item on work activity than in previous years. The nonresponse rate in 1993 was 15.1% compared to 6.2% in 1989.
‡Includes only recipients with definite employment plans. See Table A-3 explanatory note for regional definitions.
