NIH Appropriations

Why AAI Cares

Most of the nearly 8,000 AAI members (who work in academia, government, and industry) depend on NIH funding to support their work.

The $32.3 billion NIH budget for fiscal year (FY) 2016 funds more than 300,000 extramural scientists at 2,500 universities, medical schools, and other research institutions. 

Approximately 80% of the NIH budget is awarded to extramural scientists; about 10% supports the work of NIH's 6,000 intramural scientists.

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

Current NIH Appropriations

On December 18, 2015, Congress approved and President Obama signed into law an omnibus appropriations bill that provides an additional $2 billion for NIH for FY 2016, the exact increase requested by AAI in its funding recommendation for NIH.  The bill received bipartisan approval from the House (by a vote of 316-113) and the Senate (by a vote of 65-33).

The $1.1 trillion omnibus appropriations bill includes funding for all federal government agencies and programs, and increases funding for most science agencies.  The law's $2 billion increase for NIH (+6.6%) brings the total NIH budget to $32.3 billion.  It also boosts funding for the Centers for Disease Control and Prevention (+$300 million), the National Science Foundation (+$119 million), and the United States Department of Agriculture’s Agriculture and Food Research Initiative (+$25 million).

Part of the NIH funding increase was earmarked for specific programs and categories of research.  For example, the President’s new Precision Medicine Initiative (PMI) received $200 million, while the Brain Research through Advancing Innovative Neurotechnologies (BRAIN) Initiative received an increase of $85 million (for a total budget of $150 million).  The National Institute of Allergy and Infectious Diseases (NIAID) received an additional $100 million for antimicrobial resistance research.  The largest increase, $350 million, was allocated to the National Institute on Aging for research on Alzheimer’s disease.  The law also provides an increase of approximately 4% for each NIH institute and center.
