How this agency compares

These figures are calculated, not copied from the source. They use 833150 money records in the sample. Percent vs average = (this − mean of qualified hubs) / |mean| × 100. Similar hubs = 4 nearest by log10(|obligation|) and log10(award_count). HHI = sum of squared |obligation| shares × 10,000 among recipients in this cell.

Method: Sum federal_action_obligation by awarding_agency_code x US fiscal year of action_date (FY starts 1 October). Award counts are distinct contract_award_unique_key values in this sample. Deobligations (negative) are included. Min-N: agency x FY page only if award_count >= 10 or |obligation| >= 10000000. Recipient lists require at least 3 transaction rows in this sample. Recipient award_count on lists is transaction rows, labelled as such.

Rows used: 833150 money records. Amounts are US dollars. All percentages use this loaded sample only.

Questions this page can answer

Read the money with its boundaries intact

What does the amount represent?

It is the summed federal contract obligation observed in the labelled USAspending sample and period—not a complete government-spending total.

Who awarded and received it?

Use agency names, recipient identifiers, fiscal year and transaction counts together; names alone can merge unrelated entities.

Can two figures be compared?

Only compare figures built from the same sample, period and measure, with the record count visible.

What should I check next?

Open USAspending for the current complete record before relying on a figure.
