Gross National Debt Clock
The Gross National Debt represents the sum of all debts owed by the U.S. government to the holders of U.S. Treasuries, Notes and Bonds. The holders of these U.S. Treasuries are composed of people, businesses and foreign governments including China, the holder of the largest amount of U.S. Treasuries. The rest of the U.S. National Debt is Government Account Securities. This is defined as what the government owes to itself in monies borrowed from Social Security and other funds that had significant surpluses until the federal government borrowed the funds.
