Migration is no longer a movement from the rural to the urban, but rather from city to city or from the city to the metropolis in this swiftly urbanising world. This book uses new paradigms to explain why urban movements rise from the development of cities and are gradually increasing. It urges new Urban Studies to recognise that the rate of urbanisation occurring in developing regions is higher than that of developed regions and that the change is profound. A multidisciplinary approach is a prerequisite for Urban Studies to understand urban movements and the struggle for urban space in the nearby future of cities worldwide.
