Atlas of cities

More than half the world's population lives in cities, and that proportion is expected to rise to three-quarters by 2050. Urbanization is a global phenomenon, but the way cities are developing, the experience of city life, and the prospects for the future of cities vary widely from region to region. The Atlas of Cities presents a unique taxonomy of cities that looks at different aspects of their physical, economic, social, and political structures; their interactions with each other and with their hinterlands; the challenges and opportunities they present; and where cities might be going in the future.
