Between February and August 2025, the National Institutes of Health (NIH) terminated 2,291 active research grants. This administrative action withdrew $2.45 billion from the federal research budget, affecting projects across the US. While the financial scale of these rescissions is documented, a new report published in Proceedings of the National Academy of Sciences (PNAS) provides a statistical breakdown of how these terminations were distributed across different researcher demographics.
The analysis, conducted by Diego F. M. Oliveira, PhD, of the University of North Dakota, and colleagues, indicates that while no institution type or geographic region was exempt, certain cohorts experienced higher rates of cancellation. Specifically, assistant professors, postdoctoral scholars, and graduate students experienced a higher frequency of terminations than senior investigators. Researchers at these stages often manage a single primary award, making their laboratory operations more sensitive to fluctuations in funding.
Statistical distribution of funding rescissions
The data reveal a measurable difference in how the terminations affected investigators based on gender. Projects led by women were smaller on average, with median awards of $0.94 million compared to $1.4 million for projects led by men. At the time of cancellation, women-led projects also held a larger share of unspent funds—57.9 percent versus 48.2 percent for men. This suggests that a higher proportion of active research and personnel support in these labs was halted before the project’s conclusion.
Funding mechanisms focused on training and career transitions were frequently represented in the termination data. For example, 57.7 percent of F31 fellowships and 66.0 percent of T34 awards were rescinded. Among assistant professors, 59.8 percent of the terminated projects were led by women investigators. These patterns indicate that the disruptions were most concentrated in the segments of the biomedical pipeline where women and early-career scientists are most active.
Operational implications for laboratory management
For a lab manager, these findings provide a data-driven look at the vulnerabilities within the federal research ecosystem. The $2.45 billion in canceled awards is estimated to represent approximately $6.29 billion in potential economic output when applying standard NIH multipliers. Because approximately 52 percent of the allocated funds had been spent at the time of cancellation, a significant portion of the initial investment in personnel and infrastructure was not utilized for the full duration of the intended research.
Understanding these demographic trends is essential for long-term institutional planning and personnel retention. The research suggests that investigators without multiple grant portfolios or significant institutional financial buffers are the most susceptible to abrupt policy shifts. By analyzing these outcomes, laboratory leaders can better identify which team members may require additional support or strategic guidance to maintain research continuity during periods of funding instability.
