what is meant by first world and third world countries?

Answer 1

In general, Third World countries are not as industrialized or technologically advanced as OECD countries, and therefore in academia, the current term in use is "developing nation". Terms such as Global South, developing countries, less economically developed countries (LEDC), least developed countries and the Majority World have become more popular in circles where the term "third world" is regarded to have derogatory or out-of-date connotations.

The terms First World, Second World, and "Third World" can be used to divide the nations of Earth into three broad categories. "Third World" is a term first coined in 1952 by French demographer Alfred Sauvy on the model of Sieyès's declaration concerning the Third Estate during the French Revolution: "...because at the end this ignored, exploited, scorned Third World like the Third Estate, wants to become something too." The Third World later became a synonym for those nations that aligned themselves with neither the West nor with the Soviet Bloc during the Cold War. Thus, the Non-Aligned Movement was created after the 1955 Bandung Conference.
