Note. AI/AN = American Indian/Alaska Native; CHSDA = Contract Health Service Delivery Area; CI = confidence interval; IHS = Indian Health Service; RR = rate ratio. AI/AN race is created using death certificate race and IHS link. Analyses are limited to persons of non-Hispanic origin. Rates are per 100 000 persons and are age-adjusted to the 2000 US standard population. RRs are calculated in SEER*Stat before rounding of rates and may not equal RRs calculated from rates presented in table. Percent of AI/AN persons in CHSDA counties: Northern Plains = 64.8%; Alaska = 100%; Southern Plains = 76.3%; Southwest = 91.3%; Pacific Coast = 71.3%; East = 18.2%; total US = 64.2%.
