The poverty rate at Standing Rock Reservation is 43.2%, nearly triple the national average, according to Census Bureau data. The reservation, which straddles North Dakota and South Dakota, has a population of 8,956, according to the Bureau of Indian Affairs.
Some 5.2 million people (1.7% of the total U.S. population) identify as Native American or Alaska Native, with 44% identifying as at least one other race, according to 2010 Census Bureau data, the most recent data available. And census officials have said that the number of people who self-identify as such has been growing, for reasons they don’t fully understand.
There were 170,110 people nationwide who identified as Sioux in the 2010 census. The largest tribal group, Cherokee, has 819,105 people. Of those who identify as Native American or Alaska Native as their only race, one-in-three (33%) live on reservations or tribal lands. Among all American Indians and Alaska Natives, about one-in-five (22%) live on reservations or tribal lands.
