A national debt figure sounds comprehensive, but the Treasury’s definition is specific: it is outstanding borrowing by the U.S. federal government. State and local governments can also borrow to finance programs and services, yet their debts are not included in the national debt measure. The distinction matters whenever a headline number is used to describe public obligations: readers need to know which government’s balance sheet it covers. U.S. Department of the Treasury
One government’s borrowing, not every public debt
The Treasury uses “national debt,” “federal debt” and “public debt” interchangeably for the federal government’s accumulated borrowing. It describes the debt as outstanding borrowing built up over time, including securities held by the public and intragovernmental holdings. The measure does not include debts carried by state and local governments. U.S. Department of the Treasury
That boundary is about the borrower, not whether the spending serves the public. A federal program may be financed through federal revenues and borrowing; a state-funded service may be supported through a state’s own budget and financing. Both can be public responsibilities, but they do not become one account simply because they affect residents.
A hypothetical service and program
Imagine, hypothetically, that a state borrows to pay for a transit project while the federal government borrows to support a federal program. The transit borrowing belongs to the state’s debt, while federal borrowing belongs to the national debt measure. The example is illustrative and makes no claim about an actual state, project or program.
Federal spending data have their own scope, too. Treasury describes federal outlays as payments actually made, distinguishing them from obligations, which are commitments to pay. Federal spending includes programs and services as well as interest on federal borrowing. A state’s service budget does not become federal outlay merely because federal debt is discussed alongside it. U.S. Department of the Treasury
Why deficits and debt are not the same
A deficit describes a period when spending exceeds revenue; debt is the accumulated borrowing balance. Treasury explains that federal deficits are financed by borrowing, which adds to the national debt over time. That relationship describes the federal government’s accounts. Each state or local government has its own budget and borrowing decisions, so a federal deficit figure cannot be read as a combined public-sector shortfall. U.S. Department of the Treasury
Even within federal debt, the Treasury distinguishes debt held by the public from intragovernmental holdings. Those categories combine to make up the national debt, but they describe different holders of federal obligations. State and local debt sits outside that measure altogether.

Check the scope before comparing
When reading a debt figure, look first for the named borrower and the date. Does it refer to the federal government, a state, a city, or a defined combination? Then check whether the number is a stock of outstanding debt, a period’s deficit, or another accounting measure. Treasury’s daily Debt to the Penny dataset tracks federal debt outstanding; that label does not imply it includes state and local balances. U.S. Department of the Treasury
Combining levels of government may be useful for a particular analysis, but the method needs to say what is included and how overlapping claims are handled. Without a defined method, adding unlike measures can blur who borrowed, what obligations are counted and which budget pays them. Separate measures allow readers to trace those responsibilities more clearly.
