A way of looking at the debt of the United States of America is to get a break down of its outstanding loans. What organisations are borrowing money to fund operations and its value.

$15,614 Billion is borrowings from The USA’s Federal Government (US Treasury T Bonds) = US National Debt

$14,896 Billion is borrowings from The USA’s Financial Corporations

$5,232  Billion is borrowings from The USA’s Non-Financial Corporations (Regular Corporation)

Thus total debt is about £35,700 Billion = $37.7 TRILLION.

US GDP is about $17,348 Billion. Thus TOTAL Debt to GDP is about 200%.
