Data coverage and methodology

Sources: SAM.gov registration, USAspending awards and transactions, and linked supporting records. Prime contract obligations, IDV ceilings and assistance amounts are kept separate.

Disclosed relationships only. Missing records do not establish that a contractor has no partners. Ambiguous parent award identifiers are excluded.
