How to read these numbers
- Committed to this recipient
The dollars agencies committed to them — signed contracts and awarded grants — counted in the year each action happened.
- Lifetime vs. a single year
The profile sections cover the recipient's full history on record; the headline total and the flow bar reflect the fiscal year picked at the top.
- “Active in FY X”
A fiscal-year award list shows every award with at least one action that year, at its full lifetime value — a different lens from the by-year chart, which splits each award across the years it was committed.
- Names come raw
Recipient names appear exactly as filed, and the government doesn't standardize them, so one organization can show up under a few spelling variants — worth checking near-duplicates before sizing one up.
- The colored bars
Every bar on this page splits by how the money moves:
