The forms, policies, and practices of citizenship are changing rapidly around the globe, and the meaning of these changes is the subject of deep dispute. Citizenship Today brings together leading experts in their field to define the core issues at stake in the citizenship debates. The first section investigates central trends in national citizenship policy that govern access to citizenship, the rights of aliens, and plural nationality. The following section explores how forms of citizenship and their practice are, can, and should be located within broader institutional structures. The third section examines different conceptions of citizenship as developed in the official policies of governments, the scholarly literature, and the practice of immigrants and the final part looks at the future for citizenship policy.
