False. The GNI, or gross national income, is a measure of the total income generated by a country in a 12-month period. It includes the value of all goods and services produced by the people of a country, whether in the country or not. However, GNI does not measure all forms of economic development. It focuses on income, not output, and does not take into account other factors such as energy consumption, workforce distribution, availability of consumer goods, and social indicators.
