Book excerpt: In what ways do local authorities respond to the increasing socio-cultural heterogeneity of urban populations? While other studies have often focused on policy declarations, the eight chapters in this book provide rich evidence on the content and implementation of local policies. Furthermore, several chapters offer theoretical insights into the factors driving or hindering policies that acknowledge socio-cultural heterogeneity and ensure more equality and inclusive public services. The general focus of the book is on cities in France and Germany, that is, two major immigration countries in Europe - countries in which local authorities have a relatively strong position within the state structure. The contributions analyze how local actors use their powers to ensure more equal public employment, adapt cultural offers and recreational facilities to the demands of a diverse population, and/or to fight discrimination. Further chapters investigate who takes part in formulating policies and seek to explain why cities take different decisions about strategies and practices. As a whole, the book contributes to the comparative study of societal diversity and local politics in France and Germany, and will be of interest to academics, researchers, and advanced students of Sociology, Public Policy, Law, and Political Science. This book was originally published as a special issue of Ethnic and Racial Studies.
