Global suicide mortality incidence rate ratios among Indigenous and comparison populations. a Western Pacific Region (Oceania and Australia). b Western Pacific Region (East Asia). c European Region. d Region of the Americas (Canada and Brazil). e Region of the Americas (USA, National). f Region of the Americas (USA, Alaska). g Region of the Americas (Lower 48 states and Hawaii). NWT Northwest Territories, IHSA  Indian Health Services Area. The dotted line indicates a rate ratio of one (RR = 1). This means that there is rate parity (no difference) between the incidence of suicide in Indigenous and comparative populations. Rate ratios to the left of the dotted line (RR < 1) indicate that rates are comparatively higher in the non-Indigenous population. Conversely, rate ratios to the right of the dotted line (RR > 1) show that the Indigenous population has a comparatively higher rate.
