How Many Researchers: The FY 2023 Cumulative Investigator Rate  

We are pleased to share our annual snapshot of how many researchers NIH supports. These fiscal year (FY) 2023 data are also available in the NIH Data Book (see report #303) and represent awards made with traditional and supplemental coronavirus appropriations. Please keep in mind that these data are distinct from success rates, however, which are application-based metrics (see this recent post). Our cumulative investigator rate is an NIH-wide person-based metric. The metric is calculated as the number of unique principal investigators who were designated on an NIH research project grant (RPG) award, divided by the number of unique principal investigators who were designated on applications over a five-year period. For simplicity, we will refer to those investigators as either “awardees” or “applicants” in this post, even though NIH receives applications from and issues awards to institutions, not individual scientists. We focus on a five-year timeframe because most research grants last for more than one year, and applicants submit applications with the goal to secure multiple years of funding. We also only count someone once if they are designated on separate applications from the same or multiple NIH Institutes or Centers in a particular five-year timeframe. Figure 1 shows cumulative investigator rate data for RPGs between FYs 2003 and 2023. Applicants are in blue bars, awardees in orange bars, and the cumulative ...
