DOCTORAL POPULATION IN THE SCIENCES AND ENGINEERING
Distribution by Field
The estimated population of science and engineering doctorates 1 in 1995 was 542,500. For this project, the population was defined to include Ph.D.s who earned their degrees in a science or engineering field from a U.S. institution between January 1942 and June 1994 and who were age 75 or younger and residing in the United States in April 1995.
-
Twenty percent of the science and engineering Ph.D. population was composed of doctorates in biological sciences (see Table 1 ).
-
The next largest components were engineering doctorates (16 percent), psychology doctorates (15 percent), and social science doctorates (14 percent).
