Book excerpt: In The Caribbeanization of Black Politics, Sharon D. Wright Austin explores the impact of ethnic diversification of African American communities on the prospects for black political empowerment. Focusing on Boston, Chicago, Miami, and New York City—cities that for the last several years have experienced an influx of black immigrants—she surveyed more than two thousand African Americans, Cape Verdeans, Haitians, and West Indians. Although many studies conclude that African American group consciousness causes them to participate in politics at higher rates when socioeconomic status is controlled for, Wright Austin analyzes whether this is true for other black groups. She assesses the current political incorporation of these groups by looking at data on public officeholders and by examining political coalitions and conflicts among the groups, and she also discusses the possible future of black political development in these cities.
