The local turn in migration studies has drawn attention to the local level for understanding migration and migration-related diversities (Zapata-Barrero et al., 2017). This book contributes to this turn by revealing a plurality of urban diversities and exploring the factors that contribute to this plurality. Cities of migration come in various types, reflecting different diversity configurations, different locally situated inequalities, and different local approaches. There is no reason for trying to understand the dynamics of migration-related diversity in Paris and Plauen or in Rotterdam and Rouen in similar terms. These cities have very different diversity configurations, migration histories, opportunity structures and political institutional settings. Rather than defining these cities in terms of one urban model our effort is to grasp and understand the complexity of urban diversities. We see this as an important step towards a more differentiated view of urban diversities, and also a insight into the challenges that form in different cities and a better understanding of how and why cities choose different approaches towards governance of migration and diversity. Where Ingolstadt may need an approach very much tailored to the legacy of industrial migration and urban segregation, Hilversum may need an approach that is focused on the whole local population and on the role of diversity across policy sectors and domains.
