How to read these numbers

Committed through this program: Money committed under this assistance listing (its CFDA program), counted in the year each action happened.
How it's paid: Most programs pay out one way — a grant, or a direct payment to individuals; the flow bar only appears when a program genuinely mixes types.
Some recipients aren't itemized: For entitlement programs like Social Security and Medicare, the government reports one aggregate instead of naming tens of millions of people, so the recipient roster isn't part of the public record.
Awards, counted once: An award count is the number of distinct awards with at least one action that year — each counted once, however many times it was amended.
The colored bars: Every bar on this page splits by how the money moves:
