Gross national product (GNP) is the market value of all the products and services produced in one year by labor and property supplied by the citizens of a country.
Unlike gross domestic product (GDP), which defines production based on the geographical location of production, GNP allocates production based on location of ownership.
GNP is an economic statistic that is equal to GDP plus any income earned by residents from overseas investments, minus income earned within the domestic economy by overseas residents.
