What are third world countries?

Most of the third world countries are facing poverty, social, education and their healthy probelms. The term Third World was originally coined in times of the Cold War to distinguish those nations that are neither aligned with the West (NATO) nor with the East, the Communist bloc. Today the term is often used to describe the developing countries of Africa, Asia, Latin America and Oceania. Many poorer nations adopted the term to describe themselves. 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the Majority World have become more popular in circles where the term "third world" is regarded to have derogatory or out-of-date connotations. Names of third world countires are South Africa, Mexico, Brazil, China, the GCC states, India, Malaysia, Philippines, Thailand and Turkey.
