Data in these tables were derived from the National Science Foundation's (NSF's) annual surveys of Federal Funds for Research and Development and cover fiscal years 19702003. They reflect research funding levels as reported by Federal agencies in the survey series. All agencies that were identified as conducting R&D programs were surveyed.
Research totals in these tables are given in obligations. The research obligation data are further categorized according to character of work (basic research and applied research) and field of science or engineering.
The amounts reported for each year are expressed in obligations incurred or expected to be incurred in that year regardless of when the funds may have been authorized, appropriated, or received by an agency and regardless of whether the funds are identified in an agency's budget specifically for research.
Data for 1970 through 2001 are actual, representing completed transactions. Data for 2002 and 2003 are estimated because they do not represent final actions. The latest Survey of Federal Funds for Research and Development data used in these tables were collected during the second quarter of fiscal year 2002. The amounts reported for 2002 reflect congressional appropriation actions as of that period, as well as apportionment and reprogramming decisions as of that time. Data for 2003 represent administration budget proposals that had not been acted on. Authorization, appropriation, deferral, and apportionment actions that were completed after these data were collected will be reflected in later surveys of this series.
While completing the survey each year, agency respondents make revisions to their estimates for the latest 2 years of the previous report, in this case fiscal years 2001 and 2002. Such revision is part of the budgetary cycle. From time to time, survey submissions also reflect reappraisals and revisions in classification of various aspects of agencies' R&D programs. When such revisions occur, NSF requires the agencies to provide revised prior-year data to maintain consistency and comparability with the most recent concepts.
Accuracy of the data depends in part on the judgment of respondents. Because many agency R&D programs are not identified as budget-line items, agency officials must identify R&D and R&D plant activities within broader programs. Over the years personnel of the participating agencies have developed increasing skill and consistency in meeting the survey requirements, and their interaction with NSF staff has considerably increased the reliability of the data.
