More than four in five American Indian and Alaska Native women and men have experienced violence in their lifetime, and more than one in three experienced violence in the past year, according to a new report from an NIJ-funded study.The study, part of NIJ's research program on violence against American Indian and Alaska Native women, looked at how prevalent psychological aggression and physical violence by intimate partners, stalking, and sexual violence were among American Indian and Alaska Native women and men.It also examined the perpetrators' race and the impact of the violence.

Most women (83 percent) and most men (79 percent) were affiliated or enrolled with a tribe or village.

More than half of women and men (54 percent for each group) had lived within reservation boundaries or in an Alaska Native village in the past year.

The results, which show high rates of violence against both women and men, provide the most thorough assessment on the extent of violence against American Indian and Alaska Native women and men to date.

These results complement those from the National Crime Victimization Survey.

Prior to this project, there were few estimates available, and often these estimates were based on local samples.[2] The few national estimates available used very small samples, which did not always accurately represent the American Indian and Alaska Native population in the United States.[3] See "Differences Between Two National Surveys."Results show that more than four in five American Indian and Alaska Native women (84.3 percent) have experienced violence in their lifetime (see Table 1).

This includes 56.1 percent who have experienced sexual violence, 55.5 percent who have experienced physical violence by an intimate partner, 48.8 percent who have experienced stalking, and 66.4 percent who have experienced psychological aggression by an intimate partner.

Overall, more than 1.5 million American Indian and Alaska Native women have experienced violence in their lifetime.

The study also found that more than one in three American Indian and Alaska Native women (39.8 percent) have experienced violence in the past year.

This includes 14.4 percent who have experienced sexual violence, 8.6 percent who have experienced physical violence by an intimate partner, 11.6 percent who have experienced stalking, and 25.5 percent who have experienced psychological aggression by an intimate partner.
