The World Bank defines a high-income country as one with a gross national income per capita exceeding $12,056. The gross national income (GNI) is calculated by adding gross domestic product to factor incomes from foreign residents, then subtracting income earned by non-residents. Developed countries are usually classified as high-income countries. As of November 2020, 77 countries and territories are classified by the World Bank as high-income countries. Some of these countries, such as the United States, have consistently held this classification since the 1980s. Other nations, like Saudi Arabia, have held the classification, dropped off the list, and have now reappeared. Some countries, such as Russia and Venezuela, have been classified as high-income but no longer hold that distinction. These countries likely moved to middle income countries. Below is a list of countries and territories classified as high income by World Bank.
