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."
