Doctoral Population in the Sciences and Engineering

Distribution by Field top

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.
