What is the amount of money a nation government owes?

The amount of money a national government owes is referred to as its national debt or public debt. This debt is the total of all outstanding borrowings by the government, typically represented as a percentage of the country's gross domestic product (GDP). National debt can arise from budget deficits, where government expenditures exceed revenues, and is financed through the issuance of government bonds and securities. The implications of national debt can vary, influencing economic policy, interest rates, and overall fiscal health.
