• Source explains: "Some data for 2020 are preliminary and may be revised. The data for 2021 include estimates and are likely to later be revised. The federally funded data represent the federal government as a funder of R&D by all performers; similarly, the business funded data cover the business sector as a funder of R&D by all performers. The other nonfederal category includes the R&D funded by all other sources—mainly, by higher education, nonfederal government, and nonprofit organizations. The GDP data used reflect the Bureau of Economic Analysis statistics of late October 2022."
