This report represents the National Science Foundation's third projection analysis of science and engineering doctorate supply and utilization. This 1974 study incorporates several new elements. New data have been used, such as the results of the 1973 Survey of Doctoral Scientists and Engineers, and different methodologies were developed, such as those used for the projection of academic and "other science/engineering" utilization. Furthermore, the overall projections have been limited to broad areas of science, such as the physical sciences, engineering, etc., since too little is currently known about interfield mobility to make further breakdowns by individual science and engineering fields very meaningful. After the summary and introduction, the general environment for projections, the doctorate scientist and engineer utilization in 1972, and projected supply and projected utilization are presented. Appendixes include technical notes, selected related publications, text tables and charts. (Author/PG)
