U.S. R&D is performed and funded by businesses, governments, higher education, and nonprofit organizations. R&D performance refers to who conducts R&D, whether it is funded from internal funds or external financial sources (e.g., contracts, grants). From the perspective of R&D funding, funds may be devoted to own R&D or to pay for R&D in other sectors or organizations (private R&D services suppliers, academic or nonprofit grantees) (OECD 2015:126). Academic R&D is covered only briefly in this report given that the Indicators 2024 report “Academic Research and Development” provides comprehensive information for this sector.

U.S. Total R&D and R&D Intensity

U.S. Total R&D

In 2022, the United States performed an estimated $885.6 billion in R&D in current (nominal) U.S. dollars (Figure RD-1, Figure RD-2; Table RD-1), based on National Patterns statistics (Anderson 2024; NCSES 2024). This is an increase of 12% from 2021 but only of 5% in constant (inflation-adjusted) 2017 U.S. dollars.

Science and Engineering Indicators

U.S. R&D performance has been on a long-term growth trajectory since the post–World War II era, with a compound annual growth rate (CAGR) of 4% since 1953 in constant dollars (NCSES 2024, Table 1). The top three U.S. R&D-performing sectors are business, higher education, and the federal government (Figure RD-3), with business being the largest-performing sector by far, with a 78% share in 2022. The higher education sector has been the second-largest performer since 2002, remaining slightly ahead of the federal government sector since then. On the other hand, the federal government and business sectors have funded a combined share of over 90% of U.S. R&D since the 1950s, trading first and second place in 1980 when the business sector surpassed the federal government as the largest funder (Figure RD-4).

Note(s):

Some data for 2021 are preliminary and may be revised later. The data for 2022 include estimates and are likely to later be revised. Federal performers of R&D include federal agencies and federally funded research and development centers. R&D funding listed as Other combines data from nonfederal governments (state and local) and nonprofit organizations. For more information, see Table 2 and Table 6 of National Patterns of R&D Resources (2021–22 edition).
