Migration studies is entering a new era. The intellectual roots of the field stretch back at least to the nineteenth century, since which time it has focused on the drivers of human mobility and the processes of adaptation that follow. But never before has it drawn such sustained attention from so many researchers across such a broad range of backgrounds. Migration is becoming an increasingly visible and important element of human experience, and more than ever before, migration studies is becoming a distinctive and integrated field of scholarship, with its own approaches and institutions. This journal is being established to help galvanize the field still further. It aims to provide an interdisciplinary forum for leading research that develops the core concepts, data, and methods needed by migration scholars in the twenty-first century and beyond. It has several specific priorities.
