National Income is the

National Income is defined as the total value of all final goods and services produced by the residents of a country in a given year, after accounting for depreciation. It is specifically represented by the Net National Product at factor cost. This is because market prices include indirect taxes and exclude subsidies, which can distort the actual income earned by the factors of production like labor, land, and capital. By calculating it at factor cost, we measure the true cost of production and the actual income distributed among these factors. Furthermore, it uses the National concept rather than the Domestic concept because it includes Net Factor Income from Abroad, reflecting the earnings of a countrys citizens regardless of where they are located. Therefore, Net National Product at factor cost is the most accurate representation of a nations total income.
