Gross National Income (GNI) is a measure of a country's economic performance. It includes the total income earned by residents and businesses of a nation, regardless of where that income is generated. This means it accounts for income from abroad, such as investments and remittances, while excluding income earned by foreign residents within the country. GNI is often used to assess the economic health of a nation and is a key indicator for international comparisons. It helps organizations like the World Bank and International Monetary Fund evaluate development levels and allocate resources effectively.
