Absolute and Relative Declines in National Institutes of Health (NIH) Funded Basic Science Publications

An analysis of over 2.2 million NIH-funded research papers published between 1990 and 2024 reveals that there have been marked declines in the relative and absolute numbers of basic-science oriented publications. In 1990, nearly 60% of NIH-funded publications reported on basic science, with that proportion declining to 24% in 2024. The absolute number of basic science publications increased after the NIH budget doubling of 1998-2023, but at a slower rate than for human-focused publications. After the 2011-2013 budget shocks, the absolute number of basic science publications declined. These data support concerns about the long-term trajectory of NIH’s support for basic science.
