The Handbook of Urban Segregation scrutinises key debates on spatial inequality in cities across the globe. It engages with multiple domains, including residential places, public spaces and the field of education. In addition it tackles crucial group-dimensions across race, class and culture as well as age groups, the urban rich, middle class, and gentrified households. This timely Handbook provides a key contribution to understanding what urban segregation is about, why it has developed, what its consequences are and how it is measured, conceptualised and framed.
