The amounts for each state. Outlines: US Census Bureau.

An outlay occurs when federal money is actually paid out, not just promised to be paid ("obligated").
Procurement data (such as for contracts and indefinite delivery vehicles (IDV)) for the Department of Defense (DOD) and U.S. Army Corps of Engineers (USACE) are published on a 90-day delay in the Federal Procurement Data System (FPDS).
Maintaining data quality for the award description field has been persistently challenging for federal agencies.

These are the words of USAspending. Sources: USAspending.gov, About the Data (PDF, last updated 19 November 2025) and USAspending.gov, Glossary. The site copied them on 2 Oct 2026.

The amounts on this page are obligations. An obligation is a promise to pay. It is not a payment. Contract records of the Department of Defense come late, so a recent month can be low. The text under a name in a list of awards is the description that the agency wrote.
