Using data from the 2006-2010 American Community Survey (ACS), this study investigates absolute and relative poverty among American Indians and Alaska Natives. The analysis distinguishes between four racial groups of American Indians and Alaska natives including: single-race Native Americans; biracial white and Native Americans; biracial black and Native Americans; and other multi-race Native Americans. This study also reports some results for 35 of the largest self-reported tribal affiliations for single-race Native Americans. In general, all of the Native American groups have higher levels of absolute and relative poverty rates compared to non-Hispanic whites. Significant variation is, however, evident with single-race Native Americans being the most disadvantaged. Furthermore, all of these racial groups of Native Americans have higher odds of relative and absolute poverty than comparable non-Hispanic whites, after taking into account age, gender, education, metropolitan status, and residential region. The analysis also finds variation in both absolute and relative poverty across the thirty-five tribal groups compared to the overall Native American rate. Although all of the 35 major tribal groups have higher poverty rates than non-Hispanic whites, significant variation nonetheless is evident suggesting the need for further research into various tribal affiliations and tribal economy.
