Here is a report from the federal Department of Health and Human Services that shows the total number of grants (mandatory and discretionary) and total number of grant dollars awarded by each HHS operating division (agency) for Fiscal Year 2009.
The table also shows the percentage of the total number of grants, and the percentage of total grant dollars that each agency awarded with respect to the total number of grants and grant dollars awarded by all HHS agencies.
Of the total HHS grant dollars, the Centers for Medicare & Medicaid Services (CMS) awards about two-thirds; the Administration for Children & Families (ACF) awards about 20%; and the National Institutes of Health (NIH) awards less than 10%.
