What was the most violent Indian reservation in the us in 2013?

In 2013, the Pine Ridge Indian Reservation in South Dakota was often cited as one of the most violent reservations in the United States. It faced high rates of violent crime, including assaults and homicides, largely attributed to poverty, unemployment, and a lack of resources. The reservation's struggles were compounded by historical trauma and systemic issues affecting the Native American community. These factors contributed to an environment where violence was more prevalent compared to other areas.
