At the turn of the millennium, the United States has the largest number of immigrants in its history. As a consequence, immigration has emerged once again as a subject of scholarly inquiry and policy debate. This volume brings together the dominant conceptual and theoretical work on the "New Immigration" from such disparate disciplines as anthropology, demography, psychology, and sociology. Immigration today is a global and transnational phenomenon that affects every region of the world with unprecedented force. Although this volume is devoted to scholarly work on the new immigration in the U.S. setting, any of the broader conceptual issues covered here also apply to other post-industrial countries such as France, Germany, and Japan.
