Term gross domestic product and national income Definition: Gross domestic product (GDP) is the total market value of all final goods and services produced within the political boundaries of an economy during a given period of time, usually a year. National income (NI) is the total income earned by the citizens of the national economy resulting from their ownership of resources used in the production of final goods and services during a given period of time, usually one year. While the vast majority of domestic production is undertaken by domestic factors of production (national income is about 80% of gross domestic product) key differences do exist. The six main differences between gross domestic product and national income are (1) capital consumption adjustment, (2) indirect business taxes, (3) business transfer payments, (4) net foreign factor income, (5) government subsidies, and (6) statistical discrepancy.
