Step-by-step explanation:
The measure of how a nation's income is apportioned among its people is income distribution.
The GDP (gross domestic product) indicates a country's productivity and performance. It can be calculated by totaling either the income of all citizens or the value of all goods and services produced in the country during the year. The GNI (gross national income) measures the wealth of a nation and includes the value of all goods and services produced by people from a country, whether in the country or not.
Income distribution focuses on how the income is divided among the population, providing insight into the inequalities or equal distribution of wealth within a country.
