what is the defenition of "third world country"?

Answer 1

"Third World is a term first coined in 1952 by French demographer Alfred Sauvy to distinguish nations that aligned themselves with neither the West nor with the Soviet Bloc during the Cold War. Today, however, the term is frequently used to denote nations with a low UN Human Development Index (HDI), independent of their political status (meaning that the PRC, Russia and Brazil, all of which were very strongly aligned during the Cold War, are often termed third world). However, there is no objective definition of Third World or "Third World country" and the use of the term remains common. Some in academia see it as being out of date, colonialist, othering and inaccurate; its use has continued, however [1] In general, Third World countries are not as industrialized or technologically advanced as OECD countries, and therefore in academia, the more politically correct term to use is "developing nation"."

Answer 2

It started out as a term for any country that did not want to take sides or participate in the Cold War. But now, it usually applies to developing nations and those not as industrialized and technologically advanced.

Answer 3

I am going to say that it means the countries that are not industralized.
