NITRD budgets are reported in a set of 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. However, 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. Data and charts presented by this dashboard reflect that PCA evolution. See the NITRD PCA Page for details on PCA changes over time.
