Native American reservation inequality underlies a range of societal issues that affect the lives of Native American populations residing on reservations in the United States. About one third of the Native American population, about 700,000 persons, lives on an Indian Reservation in the United States. Reservation poverty and other discriminatory factors have led to persisting social inequality on Native American reservations. Disparities between many aspects of life at the national level and at the reservation level, such as quality of education, quality of healthcare, substance use disorders, teenage pregnancy, violence, and suicide rates are significant in demonstrating the inequality of opportunities and situations between reservations and the rest of the country.
