This report is the 30th in a series that covers research and development (R&D) as shown in successive Presidential budgets. The Federal budget for 1982 was unusual in the extent to which it was subjected to change, reflecting the new administration's philosophy to reduce Federal spending. R&D funding data reflect the first series of 1981 and 1982 program reductions made by the new administration. Further reductions were proposed later in the budget cycle; these changes are shown by agency and discussed in the text of the report. The analysis also provides data on R&D program changes, 1981 to 1982, as indicated in the 1983 budget. The report is divided into four sections: (1) the 1982 budget; (2) Federal R&D funding by budget function; (3) the Department of Defense (DOD) share in Federal R&D funding; and (4) geographic distribution of funds, 1980. A feature of this report (section 3) is a special analysis of R&D funding trends for the DOD. The analysis extends back to the late fifties, but places particular emphasis on programs of the seventies and the strong defense buildup in the 1980-82 period. Impacts of the recent upsurge in defense R&D support are discussed in broad terms. (Author/JN)
