Presented are detailed statistical tables showing research and development (R&D) levels for the fiscal years 1979, 1980, and 1981, reported by 95 federal agencies in the 1979 March-May period. In the tables, data for 1979 are considered to be actual; data for 1979 and 1980 are estimated. Historical data for the years 1971-1981 are contained in an appendix, reflecting a current revision of prior-year data in order to enhance the reliability of the data. This document reports funding for all agencies with R&D programs. R&D totals are given in the tables in both outlays and obligations, and the R&D obligational data are distributed by character of work, performer, field of science, and federal R&D support by states. Research performed at universities and colleges by fields of science and R&D plant data are also provided. (CS)
