Immigration has transformed the social, economic, political and cultural landscapes of global cities such as London, Melbourne, Milan and Amsterdam. The term 'superdiversity' captures a new era of migration-driven demographic diversifications and associated complexities. Superdiversity is the future or, in many cases, the current reality of neighbourhoods, cities, countries and regions, yet the implications of superdiversification for governance and policy have, until now, received very little attention. First published as a special issue of Policy & Politics, this insightful volume brings together contributions from experts across Europe to explore the ways in which superdiversity has shaped the development of policy and to consider challenges for the future.

In this book, an international group of public policy scholars revisit the stage of formulating policy solutions by investigating the basic political dimensions inherent to this critical phase of the policy process. The book focuses attention on how policy makers craft their policy proposals, match them with public problems, debate their feasibility to build coalitions and dispute their acceptability as serious contenders for government consideration. Based on international case studies, this book is an invitation to examine the uncertain and often indeterminate aspects of policy-making using qualitative analysis embedded in a political perspective.
