NIH-Funded Research Workforce

The NIH Data Book provides interactive chart visualizations and underlying data tables on extramural grants and contract awards, grant applications, NIH-supported organizations, trainees and fellows, and the biomedical workforce.

The data snapshots below depict NIH statistics on the demographics of research grant principal investigators and a downloadable report covering FY 2016 - FY 2020 is available as a downloadable PDF.

Of note, research grants are defined by the following activity codes: Research Grants (R Series), Program Projects/Center Grants (P Series), General Clinical Research Centers Programs (M Series), Research Related Programs (S Series), Research Career Programs (K Series), Cooperative Agreements (U Series, Excluding UC6), Institutional Training and Director Program Projects (DP1, DP2, DP3, DP4, DP5), and Resource Programs (G12).

Figure 1: Trends in Race/Ethnicity of NIH Supported Ph.D. Recipients

Figure 1: Bar graph showing trends in race/ethnicity of NIH-supported Ph.D. recipients. From 1995 to 2019, the vast majority of recipients were white, followed by Asian, followed by Hispanic, followed by African American and other (including multi-racial).

NIH support includes funding from any of the following Kirschstein-NRSA or NLM awards at any point prior to the Ph.D.: T15, T32, T90, TL1, TU2, F30, F31, F32, F33, F34, F35, and F99. Individuals supported by training grants (i.e., Ts) were included only if their training grant appointments were at least 100 days. Individuals supported by F99 fellowships were included only if U.S. citizens and permanent residents.

* From 1982-2000, the racial categories used in the Survey of Earned Doctorates included “Asian and Pacific Islander.” In 2001, the survey was revised and “Asian” and "Native Hawaiian or other Pacific Islander” became separate categories. For the purposes of reporting, Native Hawaiians are included in the “Other” category.

D = Subgroups with 11 or fewer recipients were suppressed to avoid disclosure of confidential information.

Figure 2: Number of NIH Principal Investigators Funded by Grant Mechanism and Race

Figure 2: Bar graph showing number of NIH principal investigators funded by grant mechanism and race in 2020. Data shows vast majority of NIH principal investigators are white, followed by Asian, then Black or African-American & more than one race. This applies across research grants, fellowships, training grants.

Includes investigators receiving both competing and non-competing awards.
Includes both Principal Investigators (PIs) and Multiple Principal Investigators (MPIs).
*Excludes awards issued using supplemental Coronavirus (COVID-19) appropriations.

Special supplemental Coronavirus (COVID-19) appropriations may include:

  • H.R.6074 (PL 116-123) - Coronavirus Preparedness and Response Supplemental Appropriations Act, 2020.
  • H.R.748 (PL 116-136) - Coronavirus Aid, Relief, and Economic Security (CARES) Act.

D = Subgroups with 11 or fewer recipients were suppressed to avoid disclosure of confidential information.

Grant Mechanisms are defined as follows: Construction Grants: Activity codes C06, UC6 and G20. Fellowships: Activity codes F05, F30, F31, F32, F33, F34, F37, F38 and F99. Other Awards: Activity codes D43, D71, DP7, G07, G08, G11, G13, OT2 and OT3. Research Grants: Extramural awards made for Research Centers, Research Projects, Small Business Innovation Research/Small Business Technology Transfer (SBIR/STTR) Grants, and Other Research Grants. Research grants are defined by the following activity codes: R, P, M, S, K, U (excluding UC6), DP1, DP2, DP3, DP4, DP5, D42 and G12. Training Grants: Activity codes T01, T02, T09, T14, T15, T32, T34, T35, T36, T37, T42, T90, TL1, TL4 and TU2. Not all of these activities may be in use by NIH every year.

The NIH has adopted the 1997 Office of Management and Budget (OMB) revised minimum standards for maintaining, collecting, and presenting data on race and ethnicity for all grant applications, contract and intramural proposals and for all active research grants, cooperative agreements, contract and intramural projects. The minimum standards are described in the 1997 OMB Directive 15, https://obamawhitehouse.archives.gov/omb/fedreg_1997standards. The 1997 OMB revised minimum standards include two ethnic categories (Hispanic or Latino, and Not Hispanic or Latino) and five racial categories (American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or Other Pacific Islander, and White). ‘Person Reporting More than one race’ under race indicates investigator who indicated more than one race. Investigators who do not disclose their race are excluded from this report.

An investigator is counted only once within each fiscal year, demographic category, and grant mechanism. For All Mechanisms, an investigator is counted only once within each fiscal year and demographic category for all mechanisms combined. Therefore, the sum of the individual mechanisms may be more than All Mechanisms, as an investigator may have received awards for more than one grant mechanism but is counted only once for that fiscal year and demographic category. Similarly, for 2016-2020, an investigator is counted only once within each mechanism and demographic category for all years combined. Therefore, the sum of the individual demographic categories may be more than 2016-2020, as an investigator may have received awards in more than one year but is counted only once for that mechanism and demographic category.

Figure 3: Number of NIH Principal Investigators Funded by Grant Mechanism and Ethnicity

Figure 3: Bar graph showing number of NIH principal investigators funded by grant mechanism and ethnicity in 2020. Data shows vast majority of NIH principal investigators are non-Hispanic with Hispanics representing a much smaller minority. This applies across research grants, fellowships, training grants.
