A developed country is a sovereign state that has a high quality of life, developed economy and advanced technological infrastructure relative to other less industrialized nations. Most commonly, the criteria for evaluating the degree of economic development are gross domestic product (GDP), gross national product (GNP), the per capita income, level of industrialization, amount of widespread infrastructure and general standard of living. Which criteria are to be used and which countries can be classified as being developed are subjects of debate. Different definitions of developed countries are provided by the International Monetary Fund and the World Bank; moreover, HDI ranking is used to reflect the composite index of life expectancy, education, and income per capita. Another commonly used measure of a developed country is the threshold of GDP (PPP) per capita of at least USD$22,000. In 2022, 36 countries fit all four criteria, while an additional 17 countries fit three out of four.
The category of newly industrialized country (NIC), newly industrialized economy (NIE) or middle income country is a socioeconomic classification applied to several countries around the world by political scientists and economists. They represent a subset of developing countries whose economic growth is much higher than other developing countries; and where the social consequences of industrialization, such as urbanization, are reorganizing society.
