Research and development (R&D) in the United States is funded and performed by a number of sectors—including the federal government, state governments, businesses, academia, and nonprofit organizations—for a variety of purposes. This fact sheet begins by providing a profile of the U.S. R&D enterprise, including historical trends and current funding by sector and by whether the R&D is basic research, applied research, or development. The final section of this fact sheet includes data on R&D performance by sector.

Historical Trends in U.S. R&D Funding

The United States became a global leader in R&D in the 20^th century, accounting forfunding as much as 70% of annual global R&D in the period following World War II.¹ Figure 1 shows the growth in total U.S. R&D expenditures from 1953 to 20131954 to 2014 in constant dollars.² In current dollars, U.S. R&D in 20132014 was 88more than 85 times higher than it was in 19531954; it was more than 12 times higher in constant dollars.³ By sector, business-funded R&D grew the most during this period.

However, faster growth in aggregate R&D spending of other nations has reduced the U.S. share of global R&D to approximately 29% in 2014.⁴

Two sectors—business and the federal government—have accounted for more than 90% of U.S. R&D funding since 1953. Federal R&D expenditures as a share of total U.S. R&D expenditures peaked in 1964 at 66.8%, the same year that business R&D expenditures reached a nadir of 30.8%. Between 1964 and 2000, the federal government's share fell and business's share rose. In 2000, business accounted for 69.2% of U.S. R&D expenditures and the federal government 25.2%. This shift in the composition of R&D funding resulted not from a reduction in federal government R&D expenditures, but rather from faster growth in business R&D expenditures. Since 1995, business has accounted for 60%-70% of total U.S. R&D each year while the federal government has accounted for 25%-3234%. (See Figure 2.)

Trends in Federally Funded R&D

In current dollars, federal funding for R&D grew from $2.83.1 billion in 19531954 to $121119.8 billion in 20132014, a compound annual growth rate (CAGR) of 6.53%. In constant dollars, federal R&D grew by a 3.12.9% CAGR during this period. Between 2009 and 2013, federal R&D fell by a 1.1% CAGR in current dollars and a 2.7% CAGR in constant dollars. In 2012 and 2013However between 2011 and 2014, federal R&D funding, as measured in current dollars, fell infor three consecutive years for the first time since 1953 (the earliest year for which data are available). Thesuch data has been collected; the total decline in federal funding for these two years was 4.9% in current dollars$9.1 billion (7.1%). In constant dollars, federal R&D declined 10.3% from 2009 to 2013; an evenfor five consecutive years from 2009 to 2014, a total drop of 13.5%; a deeper drop occurred from 1987 to 1994, when federal R&D fell by 15.8%.⁴5 Figure 3 shows federal R&D funding by budget function in constant dollars from 1955 to 2015.

Trends in U.S. Business-Funded R&D

Business funding of R&D has grown nearly every year (in current dollars) since 19531954. In current dollars, business-funded R&D grew from $2.24 billion in 1953 to $297.31954 to $318.6 billion in 20132014, a compound annual growth rate (CAGR) of 8.5%. In constant dollars, business-funded R&D grew by a 5.0% CAGR during this period. In recent years, business-funded R&D has grown at a slower pace. Between 2000 and 20132014, business R&D grew by a 3.79% CAGR in current dollars, and by a 1.68% CAGR in constant dollars.⁵

Current Composition of U.S. R&D Funding

R&D funding can be categorized by the character of the work that it supports: basic research, applied research, and development. (See text box for definitions.) Total U.S. R&D expenditures in 20132014 (the most recent year for which data are available) were $456.1477.7 billion. Of this amount, $80.584.0 billion (17.6%) was for basic research, $9093.6 billion (19.96%) was for applied research, and $285.0300.1 billion (62.58%) was for development.⁶7

Table 1 shows total U.S. R&D expenditures in 20132014 by funding sector and character of work. Figure 4 shows the samethis information graphically.

Current Composition of U.S. R&D Performance

R&D is often performed by sectors other than the one funding the R&D. For example, the federal government performs some of the research it funds, but also funds research performed by business, universities and colleges, and other organizations. Table 2 provides data on performance of U.S. R&D by sector and character of the work (basic research, applied research, and development).
