Stemming from the 2000 Census when respondents could indicate more than one racial category for the first time in history, Structural Influence on Biracial Identification is the first study of its kind to explore how urban environmental dynamics influence biracial identification in the United States.

Several different biracial pairings are incorporated into the analysis. Rachel Butts uses relative model differences to quantify the standing of each racial group on a multi-tiered racial hierarchy. Notably, Butts uses non-White biracial groups to contrast “minority” defined numerically or oppressively.

The analysis successfully extends macrostructural theory from the context of interracial marriage to the context of interracial identification. Much like interracial marriage has been used as evidence of racial integration in the past, Structural Influence on Biracial Identification presents a compelling argument for using interracial identification for measuring interracial integration in contemporary times.
