Editors Caroline B. Brettell and James F. Hollifield remain committed to include coverage that is comparative and global in scope while enhancing similarities and differences between one academic field and the next. All chapters have been revised to highlight cutting-edge issues in the field of migration studies today. The fourth edition welcomes two new authors, Professors Marie Price and François Héran, to offer a fresh approach with their chapters on geography and demography, respectively.

Designed for undergraduate and graduate courses in migration studies, a primary goal of the text is to assist instructors in guiding students who may have little background on migration, to understand important issues and the scientific debates. This ensures Migration Theory is a highly valuable guide not only to the perspectives of one's own discipline but also to those of cognate fields.
