How is GNI (Global National Income) calculated?

Global National Income (GNI) is calculated by dividing the total national income of a country by its population size. This method effectively provides an average income per person, giving insight into the economic well-being of a country's residents. GNI includes all income earned by residents of a nation, regardless of where that income is generated, and is a broader measure of a country's economic activity compared to just domestic production.

The other options do not accurately represent how GNI is calculated. Averaging the income of only the top 10% of earners would not reflect the economic status of the entire population and would skew the understanding of income distribution. Assessing the value of exports alone ignores all other income sources, such as domestic trade and services, and provides an incomplete picture of national income. Measuring the wealth of natural resources also does not relate directly to calculating GNI, as GNI is focused on income rather than asset value.
