A measure of the wealth is earned by nations through economic activates all around the world.

Gross National Income comprises the total value of goods and services produced within a country (i.e. its Gross Domestic Product), together with its income received from other countries (notably interest and dividends), and less similar payments made to other countries. It is also known as GNP.

It can be calculated as follows:

GNI = Gross Domestic Product + Net property income from abroad.
