What this counts
Outlays of the National Institutes of Health, the Department of Health and Human Services agency that funds medical research: grants to universities, hospitals and research institutes, and research in its own laboratories.
Figures are net outlays: payments made, minus any offsetting collections credited to the same accounts, as printed in the Monthly Treasury Statement. They are not adjusted for inflation. In the budget-function view it falls under health care and Medicaid.
