Self-reported race is generally considered the basis for racial classification in social surveys, including the U.S. census. Drawing on recent advances in human molecular genetics and social science perspectives of socially constructed race, our study takes into account both genetic bio-ancestry and social context in understanding racial classification. This article accomplishes two objectives. First, our research establishes geographic genetic bio-ancestry as a component of racial classification. Second, it shows how social forces trump biology in racial classification and/or how social context interacts with bio-ancestry in shaping racial classification. The findings were replicated in two racially and ethnically diverse data sets: the College Roommate Study (N = 2,065) and the National Longitudinal Study of Adolescent Health (N = 2,281).
自我报告的种族通常被认为是社会调查中种族分类的基础，包括美国人口普查。本研究借鉴人类分子遗传学的最新进展和社会科学对社会构建种族的观点，将遗传生物祖源和社会背景都纳入到对种族分类的理解中。本文完成了两个目标。首先，我们的研究将地理遗传生物祖源确立为种族分类的一个组成部分。其次，它表明社会力量在种族分类中如何超越生物学，或者社会背景如何与生物祖源相互作用来塑造种族分类。这些发现已在两个种族和族裔多样化的数据集（大学生室友研究（N=2065）和青少年健康全国纵向研究（N=2281））中得到复制。
