 Instead, the reports by Worldbank (such as the World Development Indicators (WDI) and the Global Monitoring Report) now include data aggregations for the whole world, for regions, and for income groups - but not for the “developing world”.Over the past few decades since the fall of the Soviet Union and the end of the Cold War, the term "Third World" has been used interchangeably with developing countries, but the concept has become outdated in recent years as it no longer represents the current political or economic state of the world.The three-world model arose during the Cold War to define countries aligned with NATO (the First World), the Communist Bloc (the Second World, although this term was less used), or neither (the Third World).
