Department of State is one of the data points covered by this site’s U.S. federal government spending dataset. The detail above comes directly from USASpending.gov federal awards data; the context that follows situates the headline numbers against the broader distribution across U.S. federal contracts, grants, and awards.
The methodology behind every numeric value on this page is publicly documented on the USASpending.gov federal awards data portal and described in detail on this site’s methodology page. Refresh cadence varies by underlying series; the page surfaces the as-of date for each number so readers can trace any figure back to the source release.
Practical use of this page is in combination with the comparison and ranking pages elsewhere on the site, which surface the same data for Department of State’s peers within U.S. federal contracts, grants, and awards. A single-entity reading without peer context can be misleading when an entity is an outlier on one axis but typical on another.
