The "Global South," a concept as ambiguous as it is important, means different things to different constituencies. To many in the international community today, for example, the term is a more socially acceptable cognate for what used to be referred to variously as the "Third World," the "LDCs" (less developed countries), and even the developing World. That is to say, it applied to nation-states or parts of nation-states that are poor in materials and rank low on various socioeconomic indicators. The term, used in this way, is generally credited to former West German chancellor Willy Brandt, chair of an international commission studying economic development that released the so-called Brandt Report in 1980, the formal title of which was North-South: A Programme for Survival. Because many of the poorest areas in the world were then (as today) located in the Southern Hemisphere, the term "Global South" began to be used as a sort of shorthand for any and all impoverished, exploited, economically dependent parts of the world.
