It is most commonly granted in the form of appropriations by the congressional committees assigned to determine the budget for each function.

The data tables in this report are a statistical supplement to the recent InfoBrief authored by the National Center for Science and Engineering Statistics (NCSES) (, and the technical notes in this report cover the main features of the new R&D budget authority data.
