the gap between revenues and expenditures for a government (over a given period of time); often referred to as a public deficit or fiscal deficit. In many cases, a country has administrative subdivisions that also run significant fiscal deficits, e.g., India or Argentina. The sum of state, local, and federal deficits would constitute the internal deficit of those countries.
On very rare occasions the term is applied to the deficit run by private enterprise as well as by government; in such a case, the definition is understood to mean the total debt of a country that is held by its own citizens.
Some of the largest internal deficits in the world are experienced by countries with large external surpluses. Japan in the mid-'00's was a classic example.
