This report presents findings of a special analysis designed to project science, engineering, and technician (SET) personnel requirements of both defense and nondefense sectors during the 5-year period ending in 1987 and to assess the projected supply of such personnel available to meet those requirements. Following an introduction, the report is organized into two main sections. The first section provides an overview of the Interindustry Forecasting System (IFS) that was used to generate employment projections of SET personnel. It presents pertinent assumptions underlying four scenarios chosen for analysis, and reports total and defense-related employment requirements through 1987. These requirements are presented separately for scientists (computer systems analysts and social, physical, mathematical, and life scientists), engineers (electrical/electronic, mechanical, aeronautical/astronomical engineers), and technicians (computer programmers, drafters, and science and engineering (SE) technicians). The second section describes the DauffenBach/Fiorito/Folk (DFF) labor supply model, presents information on the importance of various components of the SE labor supply, and provides comparisons of demand and supply projections to assess potential labor market balance. An assessment of projected labor market balance for SE-support technicians is also presented in this section. Information on the IFS and DFF models and supporting data (presented in 20 statistical tables) are included in appendices. (JN)
