Update and Revision History
On April 28, 2025, the data product Agricultural and Food Research and Development Expenditures in the United States was revised and updated. Data for public agricultural R&D expenditures were reported annually from 1970 to 2021 and private food R&D expenditures from 1970 to 2022. Public research expenditures were all sourced from original CRIS documents, unlike previous versions of this data product which had obtained data for some years from secondary sources. Reporting of public agricultural and food R&D was also expanded to give a breakdown of R&D performed by USDA intramural agencies and by State universities and cooperating institutions. Expenditures for private research were revised to reflect updated data on business R&D from the National Science Foundation. Inflation-adjusted expenditures for public and private research were revised from 1970 onward, using the Biomedical Research and Development Price Index (BRDPI) from the National Institutes of Health (January 2024 update).
On May 15, 2022, the data product Agricultural Research Funding in the Public and Private Sectors was revised, updated and renamed as Agricultural and Food Research and Development Expenditures in the United States. Data for public agricultural R&D expenditures and private food R&D expenditures were reported annually from 1970 to 2019. Data for R&D expenditures by private agricultural input industries continued to be reported for 1970–2014 and were not updated. Public R&D expenditures were revised from 2002 onward, using data from the new NIFA REEIS data portal. Inflation-adjusted expenditures for public and private research were revised from 1970 onward, using the Biomedical Research and Development Price Index (BRDPI) from the National Institutes of Health (February 2022 update).
On February 15, 2019, the data product Agricultural Research Funding in the Public and Private Sectors was reposted to correct an issue with how the data series Total private food and agricultural research was adjusted to avoid double counting in combining private agricultural input research data with private food research data (as some research by food manufacturing firms is also attributed to agriculture).
