Urbanization is a key process in developing countries. Within the next decade over 50 per cent of the world's population will inhabit urban areas and the majority of this growth is concentrated in developing countries. Analysing data for four large countries, this volume focuses on the relationship between economic change and urban growth. Specifically the authors examine the continued growth of industrial employment at the expense of the agricultural sector, the impact of government-controlled regional and industrial policy and the role of migration in response to employment opportunities. There are also important chapters on government responses to the lack of basic infrastructure, and the resulting negative impact on human welfare, in the cities. The volume's coherence results from the cross-country comparisons made by the authors and the conclusions that are not geographically restricted but have potential applications, by urban planners, in all developing countries.
