This is a survey of those countries that are considered to belong to the Third World or less developed countries, those that the World Bank classifies as low- or middle-income economies. The book analyzes the contribution that possession of resources makes to economic development. Guy Arnold defines resources in broad terms - not only the traditionally analyzed resources of agricultural and mineral wealth but also the less well studied resources of infrastructure and, especially, population, and the talents, education, and training of that population. In Part I, Arnold examines these resources and defines the relationship between the advanced economies of the North and the developing economies of the South. In Part II, he provides individual analysis of some 144 countries of the South in an effort to define their potential and probable development during the first few decades of the 21st century.
