Interracial Relationships in the 21st Century is an edited book that features chapters by leading scholars who study race, ethnicity, sexuality, and relationships. This second edition of the book features a new chapter that analyzes the most recent data on interracial marriages and multi-racial identity gathered in the 2010 US Census. The new first chapter also explores the impact of the election of the first African American president, Barack Obama, on the racial climate in the United States. Specifically, we explore the degree to which his election signals or establishes a post-racial America, a site of contested terrain among scholars as well as public commentators and intellectuals. The second edition of the book retains all of the original chapters that explore such topics as the relationship between religious beliefs and interracial marriage, interracial relationships among same-sex couples, the experiences of multi-racial children, intimate partner violence and interracial relationships, racial identity, and the marriage climate.
