This open access book investigates the link between income inequality and socio-economic residential segregation in 24 large urban regions in Africa, Asia, Australia, Europe, North America, and South America. It offers a unique global overview of segregation trends based on case studies by local author teams. The book shows important global trends in segregation, and proposes a Global Segregation Thesis. Rising inequalities lead to rising levels of socio-economic segregation almost everywhere in the world. Levels of inequality and segregation are higher in cities in lower income countries, but the growth in inequality and segregation is faster in cities in high-income countries. This is causing convergence of segregation trends. Professionalisation of the workforce is leading to changing residential patterns. High-income workers are moving to city centres or to attractive coastal areas and gated communities, while poverty is increasingly suburbanising. As a result, the urban geography of inequality changes faster and is more pronounced than changes in segregation levels. Rising levels of inequality and segregation pose huge challenges for the future social sustainability of cities, as cities are no longer places of opportunities for all.

Rebecca M. Blank offers the first comprehensive analysis of an economic trend that has been reshaping the United States over the past three decades: rapidly rising income inequality. In clear language, she provides an overview of how and why the level and distribution of income and wealth has changed since 1979, sets this situation within its historical context, and investigates the forces that are driving it. Among other factors, Blank looks closely at changes within families, including women’s increasing participation in the work force. The book includes some surprising findings—for example, that per-person income has risen sharply among almost all social groups, even as income has become more unequally distributed. Looking toward the future, Blank suggests that while rising inequality will likely be with us for many decades to come, it is not an inevitable outcome. Her book considers what can be done to address this trend, and also explores the question: why should we be concerned about this phenomenon?
