Immigration and Categorical Inequality explains the processes of migration, the categorization of newcomers in urban areas as racial or ethnic others, and the mechanisms that perpetuate inequality among groups. Immigration scholars apply Tilly's theoretical concepts to different historical periods and areas ranging from New York to Tokyo and from Barcelona to Nepal. The contributors of this volume describe the mechanisms producing durable inequality. This understanding is important to cease viewing differences between certain groups as natural and unchangeable. This volume will be valuable for scholars, students, and the public in general interested in understanding the periodic rise of nativism in the United States and elsewhere.
