Cities are crucibles of development. By the early 21st century most of the world's population will live in urban areas - a predicted 60 per cent by the year 2020. Since 1950, the urban population of developing countries has grown from under 300 million to over 1.7 billion, and this figure is likely to double in the next 25 years. In cities, diverse ethnic, religious and occupational groups are pressed into close proximity, and must decide how they will live together. It seems inevitable that cities are where the key issues that determine national change will be decided.
Nothing is preordained.
Much depends on how we think and plan now for the future growth of the world's cities. The problems facing the world's urban areas require immediate action. All those concerned with development must treat urban issues as a high priority. The World Bank has provided substantial support to cities in the developing world from its inception. Many billions more have been lent in support of education, social services, power and industrial development for urban areas.
