In 2009, the world’s population was estimated to be 6.8 billion people. Projections by the United Nations placed the figure at more than 9.2 billion by the year 2050 (another widely cited projection is higher, at 9.5 billion). The overwhelming majority of that population will inhabit the developing world. What will be the economic and social implications for development if such projections are realized? Is this scenario inevitable, or will it depend on the success or failure of development efforts? Finally, even more significant, is rapid population growth per se as serious a problem as many people believe, or is it a manifestation of more fundamental problems of underdevelopment and the unequal utilization
of global resources between rich and poor nations, as others argue?
