National Domestic Product (NDP) represents the total value of goods and services produced within the domestic territory of a country after accounting for depreciation. National Net Product (NNP) is derived from Net National Income (NNI) and represents the total value of goods and services produced by the residents of a country, both within and outside the domestic territory, after accounting for depreciation. The relationship is given by: NNP = NDP + Net Factor Income from Abroad (NFIA). NFIA is the difference between factor income received by residents from abroad and factor income paid to non-residents in the domestic country.
