This paper advances a model to explain the development of a healthy biracial identity among biracial children and adolescents. This model integrates five ecological components: family, community, minority context, majority context, and group antagonism. At Stage 1, from age 3 through age 7, young children explore individual and racial differences, learn labels and emotional responses associated with various ethnic groups, and begin to pick up social norms and values. At Stage 2, during adolescence, biracial individuals begin to define who they are, how they feel about themselves, and how society views them. Successful completion of both stages depends on the impact and interaction of the five ecological factors. (Contains 42 references.) (MDM)
