Book excerpt: The steady immigration of black populations from Africa and the Caribbean over the past few decades has fundamentally changed the racial, ethnic, and political landscape in the United States. But how will these "new blacks" behave politically in America? Using an original survey of New York City workers and multiple national data sources, Christina M. Greer explores the political significance of ethnicity for new immigrant and native-born blacks. In an age where racial and ethnic identities intersect, intertwine, and interact in increasingly complex ways, Black Ethnics offers a powerful and rigorous analysis of black politics and coalitions in the post-Civil Rights era.
