The concept of the First World was originally one of the "Three Worlds" formed by the global political landscape of the Cold War, as it grouped together those countries that were aligned with the Western Bloc of the United States. This grouping was directly opposed to the Second World, which similarly grouped together those countries that were aligned with the Eastern Bloc of the Soviet Union. However, as the Cold War ended with the dissolution of the Soviet Union in 1991, the definition largely shifted to instead refer to any country that boasts a well-functioning democratic system with little prospects of political risk, in addition to a strong rule of law, a capitalist economy with economic stability, and a high standard of living. Various ways in which these metrics are assessed are through the examination of a country's GDP, GNP, literacy rate, life expectancy, and Human Development Index. In colloquial usage, "First World" typically refers to "the highly developed industrialized nations often considered the Westernized countries of the world".
History
After World War II, the world split into two large geopolitical blocs, separating into spheres of communism and capitalism. This led to the Cold War, during which the term First World was often used because of its political, social, and economic relevance. The term itself was first introduced in the late 1940s by the United Nations. Today, the terms are slightly outdated and have no official definition. However, the "First World" is generally thought of as the capitalist, industrial, wealthy, and developed countries. This definition includes the countries of North America and Western Europe, Japan, South Korea, and Australia. In contemporary society, the First World is viewed as countries that have the most advanced economies, the greatest influence, the highest standards of living, and the greatest technology. After the Cold War, these countries of the First World included member states of NATO, U.S.-aligned states, neutral countries that were developed and industrialized, and the former British Colonies that were considered developed.
According to Nations Online, the member countries of NATO during the Cold War included:
Belgium, Canada, Denmark, France, Germany, Greece, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Turkey, the United Kingdom, and the United States.
The US Aligned States included:
Israel, Japan, and South Korea.
Former British Colonies included:
Australia and New Zealand.
Neutral and more or less industrialized capitalist countries included:
Austria, Ireland, Sweden, and Switzerland.
Shifting in definitions
Since the end of the Cold War, the original definition of the term "First World" is no longer necessarily applicable. There are varying definitions of the First World; however, they follow the same idea. John D. Daniels, past president of the Academy of International Business, defines the First World to be consisting of "high-income industrial countries". Scholar and Professor George J. Bryjak defines the First World to be the "modern, industrial, capitalist countries of North America and Europe". L. Robert Kohls, former director of training for the U.S. Information Agency and the Meridian International Center in Washington, D.C., uses First World and "fully developed" as synonyms.
