While it is estimated that rates of violence on reservation can be up to ten times higher than national averages, research is missing on rates of murder violence among American Indian and Alaska Native women living in urban areas. An NIJ-funded study from 2008 found that the rates of violence on reservations are much higher than the national average.
However, according to the Urban Indian Health Institute, no research has been done on the rates of such violence among American Indian and Alaska Native women living in urban areas despite the fact that approximately 71 percent of American Indian and Alaska Natives live in urban areas.
Moreover, reports indicate that there is no reliable count of how many Native women go missing or are killed each year.
Side Note: The FBI is in charge of investigating violent crimes and homicides in Indian country but apparently only the assignment to Indian Country is frequently a "punishment assignment" so they have that going for them.
Researchers have found that women are often misclassified as Hispanic or Asian or other racial categories on missing-person forms and that thousands have been left off a federal missing-persons.(Source: www.bia.gov)
