A company's research and development (R&D) expenditures are typically reported in the income statement, which can be found in several resources including, but not limited, to:

• Hoovers
• S&P Capital IQ (see access details) or S&P NetAdvantage
• PitchBook
• Bloomberg (see access details)

R&D expense information is available in Compustat on WRDS (see access details); select XRD-Research and Development Expense under Income Statement items. Research Quotient on WRDS also calculates the percentage increase in revenue from a 1% increase in R&D; data available from 2004-2015.

Use the National Science Foundation's National Center for Engineering Statistics (NCSES).

• Use the Business and Industrial R&D series as well as the Federal R&D Funding by Budget Function.
• You can also browse the Research and Development category in the Publication Index for access to R&D-related reports.

For OECD countries, research and development expenditures by industry are available in STAN (Structural Analysis Statistics) and overall expenditures and employment are available as science and technology indicators; from OECD iLibrary, select Statistics, then choose either Databases-->STAN or Indicators-->Research & Development (R&D).

Statistical Abstract of the United States, published by the U.S. Census Bureau through 2012, then ProQuest from 2013 to present, contains R&D statistics in its Science & Technology section.
