Asian Americans are one of the fastest-growing minorities in the United States and show the highest outmarriage rate; yet little research has investigated the racial identity of multiracial Asians. This study explores the racial identity of multiracial Asians in the United States, using survey data on 110 Asian-white adults, and examines the factors that shape this identity. The literature suggests a number of factors; drawing on the theoretical framework of reflected appraisals, I hypothesize that certain factors will be more important than others in this process. When respondents were asked with which race they identified more strongly, Asian or white, two factors were shown to exert the strongest influence on racial identity, namely phenotype and cultural exposure. Logistic regression and qualitative responses reveal that the racial identities of this sample of Asian-white adults are shaped largely by the reflected appraisals of others regarding their appearance and cultural knowledge.
