FY19: Estimate, FY20: Request
As required by law, the annual NITRD Supplement to the President’s Budget is organized by Program Component Areas (PCAs), where the PCAs are major subject areas for federal IT R&D. PCAs are intended to facilitate budgetary comparisons from year to year in each area. The PCA set does evolve over time, reflecting changes in IT R&D activities at federal agencies and IT R&D priorities of the Administration. For general information about NITRD PCAs, see the NITRD PCA main page.
