Useful Stats: How has the relationship between GDP and R&D changed since the 1950s?
Total research and experimental development (R&D) performed in the U.S. reached nearly $1 trillion of expenditures in 2024, reveals new data from the National Center for Science and Engineering Statistics (NCSES). This represents a 6% increase over the prior year, a 101% increase in the past 10 years, and a nearly 16,000% increase in the past 70 years.

Adjusted for inflation, total R&D expenditures, relative to their 2024 values, have increased more modestly but still reflect impressive growth: 3% since 2023; 56% in the 10 years since 2015; and approximately 1,670% in the 70 years since 1955.
Figure 1 below includes two line charts, each with a line for billions of current and constant (2017) USD: GDP on the left and R&D expenditures on the right. Periods of recession are highlighted in grey for applicable years. Note that each chart has a different y-axis.
Useful Stats: An international comparison of R&D expenditures
Most countries have dramatically increased their investments in R&D over the past two decades, with OECD nation spending reaching a record high nearly $1,600 of gross domestic expenditure on R&D (GERD) per person in 2023 (PPP[1] converted), approximately triple the value recorded in 2000. Although the U.S.
Useful Stats: US leads the world in GDP, falls behind in R&D intensity
With a GDP of over $23 trillion in 2021, the United States has the world's largest economy, according to the latest available data from the World Bank. Yet, the U.S. falls behind such countries as Israel and Korea when it comes to how much is spent on research and development (R&D) in proportion to GDP. For example, Israel and Korea spend 5.56% and 4.93% of their GDP on R&D compared to the U.S.’ 3.46%.
