first world

The phrase "first world" is a term used in the field of international relations and development economics to categorize countries based on their level of economic development, political stability, and social welfare. Originally, it referred to the allied countries (including the United States, Western European nations, and their allies) during the Cold War era, which were generally characterized by a capitalist or market-oriented system, a high standard of living, and strong political institutions. However, over time, the use of "first world" has evolved to encompass developed nations with advanced economies, industrialization, robust infrastructure, and high human development index scores.
