National Income: The gross national product comprises the total value added produced by a national economy and benefiting persons living in that country. Deduction of depreciation and indirect taxes results in the net national product at factor costs. If the net national product is calculated at market prices, the result obtained is the national income at market prices. Pensions are not included in the national income, while social security contributions are (through wages and salaries). In 1993, the national income at market prices in Austria amounted to ATS 1,389 thousand million, while the national income at factor costs was ATS 1,564 thousand million. These figures comprise remuneration for employed persons (73%) and income from property and business as well as undistributed corporate profits.
