CRS Report – Tracking Federal Awards: USAspending.gov and Other Data Sources, Updated April 26, 2022: “USAspending.gov, available at http://www.USAspending.gov, is a government source for data on federal awards by state, congressional district (CD), county, city, and zip code. The awards data in USAspending.gov are provided by federal agencies and represent contracts, grants, loans, and other forms of financial assistance. USAspending.gov also provides tools for examining the broader picture of federal spending obligations within the categories of budget function, agency, and object class. Using USAspending.gov to locate and compile accurate data on federal awards can be challenging due, in part, to continuing data quality issues that have been identified by the U.S. Government Accountability Office (GAO). Users of USAspending.gov need to be aware that while search results may be useful for informing consideration of certain questions, these results may be incomplete or contain inaccuracies. USAspending.gov was created under P.L. 109-282, the Federal Funding Accountability and Transparency Act of 2006 (FFATA), and later enhanced under requirements in P.L. 113-101, the Digital Accountability and Transparency Act of 2014 (DATA Act).
