What does Gross National Income measure?

"Where the Money Is The Top 20 Gross National Income Per Capita* US$ South Sudan 233 * Gross National Income is the value of the final goods and services produced by a country (Gross Domestic Product) together with its income received from other countries (such as interest and dividends) less similar payments made to other countries. Final goods are the goods ultimately consumed rather than used in the production of another good. For example, a car sold to a consumer is a final good; the components, such as tires sold to the car manufacturer, are not. They are intermediate goods used to make the final good. The same tires, if sold to a consumer, would be a final good. Sources: Some data refers to IMF staff estimates and some are actual figures for the year 2017, made on April 12, 2017.
