A high-income economy is defined by the World Bank as a country with a gross national income per capita of US$13,845 or more in 2022, calculated using the Atlas method.^[1] While the term "high-income" is often used interchangeably with "First World" and "developed country," the technical definitions of these terms differ. The term "first world" commonly refers to countries that aligned themselves with the U.S. and NATO during the Cold War. Several institutions, such as the Central Intelligence Agency (CIA) or International Monetary Fund (IMF), take factors other than high per capita income into account when classifying countries as "developed" or "advanced economies." According to the United Nations, for example, some high-income countries may also be developing countries. The GCC countries, for example, are classified as developing high-income countries. Thus, a high-income country may be classified as either developed or developing.^[2] Although Vatican City is a sovereign state, it is not classified by the World Bank under this definition.

Historical thresholds

The high-income threshold was originally set in 1989 at US$6,000 in 1987 prices. Thresholds for subsequent years were adjusted taking into account the average inflation in the G-5 countries (the United States, the United Kingdom, Japan, Germany, and France), and from 2001, that of Japan, the United Kingdom, the United States, and the eurozone.^[4] Thus, the thresholds remain constant in real terms over time.^[3] To ensure no country falls right on the threshold, country data are rounded to the nearest 10 and income thresholds are rounded to the nearest 5.^[5]

The following table shows the high-income threshold from 1987 onwards. Countries with a GNI per capita (calculated using the Atlas method) above this threshold are classified by the World Bank as "high-income economies."^[3]
