Book excerpt: The concept of "social exclusion" has been widely adopted to describe the conditions of economic, social, political, and/or cultural marginalization experienced by particular groups of people due to extreme poverty, discrimination, dislocation, and disenfranchisement. Social Exclusion in Cross-National Perspective examines the impacts of social exclusion on disadvantaged populations across four countries--China, India, South Korea, and the United States--and provides a rich account of the interplay between globalization and social exclusion, as well as how policies and social action respond to it.
