Between 1990 and 2000, every fourth city in the world was shrinking, and this tendency is on the rise. Which urban areas are people leaving? How is it happening? And why now? The Atlas of Shrinking Cities answers these questions and many more in some 30 world maps, 50 diagrams, 30 city portraits and 15 encyclopedic essays, documenting a global phenomenon in innovative cartography and graphics that make complex information and conclusions easily visually comprehensible. Four chapters of maps, illustrations and statistics explain reasons for shrinkage ranging from demographic developments and migration flows to increasingly limited resources, the destruction of nature and the evolution of the character of human settlements. Case studies on all continents shed light on the real effects of the global transformation process, and the index lists population development over the past 50 years in all cities of more than 100,000 inhabitants.
