USAspending.gov is a new US governmental website designed in accordance to the Federal Funding Accountability and Transparency Act of 2006 (Transparency Act): it is a single searchable website, accessible by the public for free that includes for each Federal award:

1. the name of the entity receiving the award;
2. the amount of the award;
3. information on the award including transaction type, funding agency, etc;
4. the location of the entity receiving the award;
5. a unique identifier of the entity receiving the award.

The data is largely gathered from the Federal Procurement Data System, which contains information about federal contracts, and the Federal Assistance Award Data System, which contains information about federal financial assistance such as grants, loans, insurance, and direct subsidies like Social Security. The underlying technology for USAspending.gov was developed by OMB Watch with the support of The Sunlight Foundation and is used on OMB Watch's website located at FedSpending.org.

Most of the visualizations are displayed in the Federal IT Dashboard. For instance, the current illustrates government spending in the form of charts and lists ranking the largest government contractors (e.g. Lockheed, Boeing, Northrop Grumman, etc.) and assistance recipients (e.g. Department of Healthcare Services, New York State Dept. of Health, Texas Health & Human Services Commission, etc.).
