This study is limited to science and engineering doctorates (both PhD and Doctor of Arts) and spans the period 1969 to 1980--a period for which most of the factors likely to have a significant effect on the supply and utilization of doctorates are known or can be reasonably anticipated. The basic methodology involves statistically projecting past and current trends, including reasonable variations, into the future. Projections cover the areas of engineering, physical sciences, social sciences, life sciences and mathematics. They indicate an expected 315,000-336,000 doctoral scientists and engineers available to the US economy in 1980, compared to 270,000-297,000 available positions, and continuation of the movement away from graduate teaching and R&D activities as the major utilization of doctorates. The data are presented in charts and tables and are accompanied by discussion. (JS)
