Tracking Federal Awards in States and Congressional Districts Using USAspending.gov [Updated November 26, 2019] [open pdf - 441KB]
From the Overview: "USAspending.gov, available to the public at http://www.USAspending.gov, is a government source for data on federal awards by state, congressional district (CD), zip code, city, and county. The awards data in USAspending.gov is provided by federal agencies and represents grants, contracts, loans, and other financial assistance. Grant awards include money the federal government commits for projects in states, local jurisdictions, regions, territories, and tribal reservations, as well as payments for eligible needs to help individuals and families. Contract awards refer to bids and agreements the federal government makes for specific goods and services. USAspending.gov does not include data on actual spending by recipients. 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 presents challenges, in part, because of continued data quality issues that have been identified by the U.S. Government Accountability Office (GAO). Researchers need to be aware that search results may be incomplete or contain inaccuracies."
