NIH-Funded Medical Research Provides A Significant Return on Our Nation’s Investment

The National Institutes of Health (NIH) is the principal federal funder of medical research. An agency of the U.S. Department of Health and Human Services (HHS), NIH comprises 27 Institutes and Centers.
The bulk (83 percent) of NIH-supported research is conducted through 50,000 grants awarded to 325,000 researchers at more than 3,000 institutions (extramural research); more than half of all extramural funding supports researchers at the nation’s medical schools and many major teaching hospitals. About 10 percent of the NIH budget supports intramural research, or research conducted by the NIH’s 6,000 scientists in its own laboratories, while the remaining 7 percent supports research management and other activities.
