Intramural Research Program (IRP) Demographics

The Intramural Research Program (IRP) is a distinctive research environment with several dedicated NIH campuses across the country. Representing a collection of interdisciplinary teams, the IRP conducts research from bench to the bedside in the pursuit of scientific opportunity. 

Figure 1 summarizes end of fiscal year 2021 (FY21) published data on the demographic composition of the NIH IRP workforce as of September 30, 2021. Data is broken down by Intramural Professional Designations (IPDs) and Race/Ethnicity.

Data Notes:

  1. Office of Intramural Research (OIR), 9/30/2021.
  2. Human Resources data in NIH nVision, 9/28/2021.
  3. nVision contains IPD information only for appointments under Title 42. Thus, nVision Staff Clinician and Staff Scientist numbers do not include those with appointments under Title 5, Title 38 or the PHS Commissioned Corps. For StSc there is a very small number in T5, mostly legacy (<50).
  4. For Staff Clinicians, the most accurate number shown on the table is a combination of those in nVision (235) plus those uniquely on the Clinical Center Credentialing Office list of StCl, who are confirmed employees in other pay systems (Commissioned Corps, T5, T5/T38) by OHR (109), since the credentialed list also includes non-FTEs (e.g., volunteers, contractors). The numbers shown are only FTEs.
  5. NIH nVision - Fellowship Payment System, 9/28/2021.
  6. Office of Intramural Training and Education (OITE), OIR.
  7. 835 of these were summer interns through the Summer Internship Program (SIP), which for 2021 was only virtual due to the COVID-19 pandemic.
