This book puts forth a science of cities to help prepare for the mass urban in-migration expected by 2050, by which time 70 percent of the global human population is expected to live in metropolitan areas, according to the Untied Nations. Drawing on data from the Atlas of Urban Expansion, which uses satellite imagery to measure urban growth and related factors, it provides planners, elected officials, and other policy makers with the conceptual framework, basic empirical data, and practical agenda necessary to manage development at sustainable densities throughout the world.Â  Â
