NIH Appropriations

NIH funding is vital to the careers of many AAI members and the biomedical research enterprise as a whole.

The $39.1 billion NIH budget for fiscal year (FY) 2019 funds more than 300,000 extramural scientists at 2,500 universities, medical schools, and research institutions. Approximately 80% of the NIH budget is awarded to extramural scientists; about 10% supports the work of NIH's nearly 6,000 intramural scientists. (see:

NIH funding has a huge impact on the advancement of biomedical research and on the economy (local, state, national, and international).


In September 2018, Congress passed, and the President signed, an appropriations bill that includes a $2 billion funding increase for NIH for FY 2019, bringing the total NIH budget to $39.1 billion. This is the fourth year in a row that NIH received a significant funding increase: the NIH budget has increased by $9 billion (30%) over that period of time. This is also the first time in 22 years that the NIH budget has been finalized prior to the beginning of the next fiscal year (the fiscal year began October 1, 2018).

More than half of the $2 billion increase is allocated to specific programs and diseases, including:

All NIH Institutes and Centers also received funding increases in the bill, with most of the increases averaging around three percent. The National Institute of Allergy and Infectious Diseases (NIAID) received a five percent boost, while the National Institute on Aging (NIA) is one of the major outliers, receiving an increase of about 20 percent (because of the new funding for Alzheimer’s disease research, described above).
