This report provides information on total federal research and development (R and D) funding by function during the fiscal years 1969-74. The report is divided into two parts. Part 1 gives an overall view of priorities funded by the federal government. The total federal R and D expenditures are arranged by functions and are listed in descending order of 1974 R and D obligations. In addition, a brief statistical account is presented about the trend in funding between 1969-74 for each function as well as comments on dominant subfunctions in each category. Part 2 provides a detailed treatment of R and D expenditures, function by function. Under each major function, data are gathered for different subfunctions and their ratios to total outlays. The data for years previous to 1974 are compiled and presented according to subfunction. The arrangement of subfunctions under major function titles is in descending order based on 1974 funding. Important trends are noted and analyzed for each function. The tables are presented in the appendix for figures for each year during 1969-74 according to agency programs. (BR)
