Socioeconomic Stratification from Within: Changes Within American Indian Cohorts in the United States: 1990-2010

Socioeconomic inequality in the United States persists with disparities in education, earnings, and health evident across racial and ethnic groups. Somewhat less attention has been given to the importance of inequality within minority racial and pan-ethnic groups. This paper considers the increasing divergence of socioeconomic status within cohorts of American Indian and Alaskan Native (AIAN) adults in the United States. The analyses rely on US Census data for 1990, 2000, and 2010 to examine the relative contribution of demographic change and change in self-identification to the size of AIAN adult cohorts over time. Decomposition analyses demonstrate that declines in poverty within the AIAN cohorts are largely attributable to the more advantaged status of individuals who select AIAN in combination with other racial identifications.
