Remarkably, more than half the world's population now lives in cities, and the numbers grow daily as people abandon rural areas. This fully updated and revised fourth edition of the classic text offers readers a comprehensive set of tools for understanding the urban landscape, and, by extension, the world's politics, cultures, and economies. Providing a sweeping overview of world urban geography, a group of noted experts explores the eleven major global regions. Each author presents the region's urban history, economy, culture and society, as well as urban spatial models and problems and prospects. Environmental, human security, globalization, and cyberspace topics are fully developed as well. Vignettes of seventy-eight key cities give the reader a vivid understanding of daily life and the 'spirit of place.' An introductory chapter presents an overview of key terms and concepts, and a concluding chapter projects the world's urban future. Liberally illustrated with a new selection of photographs, maps, and diagrams, the text also includes a rich array of boxes to highlight key topics ranging from gender and the city to Islamic fashion and global warming. Bibliographic sources, websites, and an appendix of UN data provide additional resources for helping students understand more about the urban world. Clearly written and timely, this text will be invaluable for those teaching introductory or advanced classes on global cities, regional geography, and urban studies.
