national income

total amount of income earned by the residents of a country in a specified amount of time

Measures of national income and output are used in economics to estimate the value of goods and services produced in an economy. They use a system of national accounts or national accounting first developed during the 1940s. Some of the more common measures are Gross National Product (GNP), Gross Domestic Product (GDP), Gross National Income (GNI), Net National Product (NNP), and Net National Income (NNI). Formerly in the Soviet Union and its friendly states COMECON, Net Material Product (NMI) was estimated (NNP-Services). In relation to greening the national accounts the United States Congressional Budget Office concludes "a gradual process of modifying measures of national economic performance is consistent with the history and development of the national accounts."[1]
