The document discusses the term "Third World" and its evolution over time. Originally during the Cold War, Third World referred to non-aligned countries that were not part of the Western or Eastern blocs. Now the term is commonly used to refer to the poorest, least developed countries. There is no clear definition of what constitutes a developing country, but factors like access to basic needs, a stable political system, and human development are discussed. Human development is defined by the UN as creating opportunities for people to lead productive lives according to their needs and interests.
