This report presents the 2011 Montana Youth Risk Behavior Survey high school student frequency distributions for American Indian students on or near a reservation. These frequency distributions are based upon surveys with 720 high school American Indian students on or near a reservation in Montana during February of 2011. Frequency distributions may not total 720 due to nonresponse and percents may not total 100 percent due to rounding.
