note: data cover only what the United States Treasury denotes as
"Debt Held by the Public," which includes all debt instruments
issued by the Treasury that are owned by non-US Government entities;
the data include Treasury debt held by foreign entities; the data
exclude debt issued by individual US states, as well as
intra-governmental debt; intra-governmental debt consists of
Treasury borrowings from surpluses in the trusts for Federal Social
Security, Federal Employees, Hospital Insurance (Medicare and
Medicaid), Disability and Unemployment, and several other smaller
trusts; if data for intra-government debt were added, "Gross Debt"
would increase by about 30% of GDP
