A developed country, or advanced country, is a country 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 income (GNI), per capita income, level of industrialization, amount of widespread infrastructure and general standard of living.Developed Economy Definition . Investopedia (16 April 2010). Retrieved 12 July 2013. 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 United Nations Department of Economic and Social Affairs (UNDESA), the World Bank, the Development Assistance Committee (DAC), the International Monetary Fund (IMF), the Paris Club and the United Nations Industrial Development Organization (UNIDO), while the Human Development Index is used to rank countries on the composite basis of life expectancy, education, and income per capita.

Developed countries have generally more advanced post-industrial economies, meaning the tertiary sector provides more wealth than the secondary sector. They are contrasted with developing countries, which are in the process of industrialisation or are pre-industrial and almost entirely agrarian, some of which might fall into the category of least developed countries. , advanced economies constitute 57.3% of global GDP based on nominal value and 41.1% of global GDP based on purchasing power parity (PPP) according to the IMF.

Definition and criteria Economic criteria have tended to dominate discussions. One such criterion is the income per capita; countries with the high gross domestic product (GDP) per capita would thus be described as developed countries. Another economic criterion is industrialisation; countries in which the tertiary and quaternary sectors of industry dominate would thus be described as developed. More recently, another measure, the Human Development Index (HDI), which combines an economic measure, national income, with other measures, indices for life expectancy and education has become prominent. This criterion would define developed countries as those with a very high (HDI) rating. The index, however, does not take into account several factors, such as the net wealth per capita or the relative quality of goods in a country. This situation tends to lower the ranking of some of the most advanced countries, such as the G7 members and others.

According to the United Nations Statistics Division: There is no established convention for the designation of "developed" and "developing" countries or areas in the United Nations system.

And it notes that: The designations "developed" and "developing" are intended for statistical convenience and do not necessarily express a judgement about the stage reached by a particular country or area in the development process.

Nevertheless, the UN Conference on Trade and Development (UNCTAD) considers that this categorization can continue to be applied: The developed economies broadly comprise Northern America and Europe, Israel, Japan, the Republic of Korea, Australia, and New Zealand.

Terms linked to the concept developed country include "advanced country", "industrialized country", "more developed country" (MDC), "more economically developed country" (MEDC), "Global North country", "first world country", and "post-industrial country". The term industrialized country may be somewhat ambiguous, as industrialisation is an ongoing process that is hard to define. The first industrialized country was the United Kingdom, followed by Belgium. Later it spread further to Germany, United States, France and other Western European countries. According to some economists such as Jeffrey Sachs, however, the current divide between the developed and developing world is largely a phenomenon of the 20th century.

Mathis Wackernagel calls the binary labeling of countries as "neither descriptive nor explanatory. It is merely a thoughtless and destructive endorsement of GDP fetish. In reality, there are not two types of countries, but over 200 countries, all faced with the same laws of nature, yet each with unique features."

A 2021 analysis proposes the term emerged to describe markets, economies, or countries that have graduated from emerging market status, but have not yet reached the level equivalent to developed countries. Multinational corporations from these emerging markets present unique patterns of overseas expansion and knowledge acquisition from foreign countries.

Economy lists by various criteria

Human Development Index (HDI)

The UN HDI is a statistical measure that gauges an economy's level of human development. While there is a strong correlation between having a high HDI score and being a prosperous economy, the UN points out that the HDI accounts for more than income or productivity. Unlike GDP per capita or per capita income, the HDI takes into account how income is turned "into education and health opportunities and therefore into higher levels of human development."

Since 1990, Norway (2001–2006, 2009–2019), Japan (1990–1991 and 1993), Canada (1992 and 1994–2000) and Iceland (2007–2008) have had the highest HDI score.

The following countries in the year 2023 are considered to be of "very high human development":

UNIDO high-income industrial economies

According to the United Nations Industrial Development Organization (UNIDO), 48 countries and one territory are categorized as "high-income industrial economies". This classification, first implemented in 2022, is assigned to economies that have achieved a high national income through a development path resulting in high levels of industrialization. UNIDO determines this status by evaluating three core dimensions of the manufacturing sector: value added (manufacturing value added per capita), historical employment share, and the quality of exports (average exports of medium- and high-technology products). Previously, UNIDO's top-tier classification of "industrialized economies" included countries that were not high-income economies, e.g. Belarus and Malaysia.
