This Google Sheet aggregates publicly available data to track grants rescinded by NIH since January 20, 2025. Tabs include information for specific classes of grants.

A key source of information in this spreadsheet comes directly from affected PIs reporting their terminated grants.

Given limitations of Google Sheets, we have also created an Airtable database that contains the same information contained within this spreadsheet. The Airtable enables uses to search for, explore, and categorize terminated grants in multiple ways.

Our methods:

A NOTE OF CAUTION:
The NIH grant termination process has been extraordinarily chaotic--far more so than has been reported. In many cases, the government has often provided incorrect and shifting information (knowingly or not) about exactly which grants were terminated, when, and why. Their estimates of the dollar value of grants terminated are even more unreliable. In some cases, we believe the government has restored grants that it previously terminated, often without providing public notice.

Thus, data presented here and in the accompanying Airtable are an effort to organize and clarify some of this uncertainty. However, given the chaotic nature of the moment, our dataset almost surely contains some inaccuracies. To reduce these inaccuracies and bolster confidence in our dataset, we briefly decribe a portion of our methods below. Please contact us with additional questions or concerns.

Data in this spreadsheet are from several sources. Among them are affected Principal Investigators, who we encourage to information on their terminate grants using the link below. We also aggregate data from news reports, the HHS TAGGS system, DOGE.gov, USASpending.gov, NIH's Twitter feed, and NIH RePORTER. The HHS TAGGS system provides data in two ways. First, it details grant-based financial transactions with information that is updated at least daily. Second, TAGGS administrators periodically (~1/week) release a PDF list of cancelled grants. The TAGGS PDF list, which many users have kindly sent our way, is one source of information in this spreadsheet among several. Because we aggregate from multiple sources, this spreadsheet includes grants not yet listed on federal government websites, including the HHS TAGGS PDF of cancelled grants.

Grants are classified on different tabs using multiple criteria. We identify grants investigating specific topics (e.g., LGBTQ health or "DEI" topics) based on the presence of "flagged words" that may appear in each grant's title, abstract text, public health relevance statement, or project terms as they appear on NIH RePORTER. "Flagged words" are those previously identified by the New York Times (link below) as words the current administration seeks to purge from Federal programs. Some flagged words (e.g., "bias") have multiple meanings in scientific literature. To reduce misclassification, we use a subset of the NYT flagged words list to classify grants based by subject matter. Separately, we also classify grants based on the home institution of the grant's Principal Investigator (i.e., awardee organization) to facilitate analysis of grants terminated at Columbia University.

The complete list of flagged words is here: https://www.nytimes.com/interactive/2025/03/07/us/trump-federal-agencies-websites-words-dei.html.
