Scholarship designed to ask questions about the meanings of, identities of, and experiences of the offspring of interracial unions has been around for almost a century but has only seriously and significantly developed since the 1990s. From the early days of theorizing such experience from the counselor’s chair, psychological models planted early seeds, yet the ground of multiracial experience was one fundamentally wrapped up with institutions, social structures, political movements, histories and stories, racialization and microaggressions, family and peer dynamics, and other important social, cultural, economic, historical, collective, and political realities. Multiracial scholarship developed early on from an interest in understanding how the offspring of interracial unions, whether white/black, black/Asian, Latinx/white, and so on, develop understandings of themselves, as well as how others influence that understanding; thus, identity was a crucial starting point. Appearances, phenotype, and the sociocultural models of racial classification and the role that these play in the complex process of multiracial identity formation, development, maintenance, and change have become staple research questions. The racial demographics of race and multiraciality, along with the politics of census categorization and the tracing of such demographic and policy shifts over time, have provided more-macro contexts that have played into the ways we both study and, therefore, understand multiraciality. In the 2010s, scholars really began to move outside the black-white binary, more intersectionally and transdisciplinarily, and across national and historical contexts to develop an even more nuanced and complex theoretical and empirical understanding of multiraciality. From early-21st-century developments in critical mixed-race theory to the political importance of multiraciality in social movements, and from the role of multiraciality in popular culture and marketing to the potential and pitfalls of multiraciality and its politics dismantling ideas of race, realities of racism, and the pursuit of racial and social justice, scholarship on multiraciality has given us deeply important understandings.
