Note. AI/AN = American Indian/Alaska Native; CI = confidence interval; RR = rate ratio. Infant is defined as < 1 year; neonatal is defined as < 28 days, and postneonatal is defined as 28–364 days. Analyses are limited to persons of non-Hispanic origin. AI/AN race is reported from death certificates or through linkage with the Indian Health Service patient registration database. Rates are per 100 000 persons and are age-adjusted to the 2000 US standard population (11 age groups; Census P25-1130).27 RRs are calculated in SEER*Stat before rounding of rates and may not equal RRs calculated from rates presented in table. Indian Health Service regions are defined as follows: AKa; Northern Plains (IL, IN,a IA,a MI,a MN,a MT,a NE,a ND,a SD,a WI,a WYa); Southern Plains (OK,a KS,a TXa); Southwest (AZ,a CO,a NV,a NM,a UTa); Pacific Coast (CA,a ID,a OR,a WA,a HI); East (AL,a AR, CT,a DE, FL,a GA, KY, LA,a ME,a MD, MA,a MS,a MO, NH, NJ, NY,a NC,a OH, PA,a RI,a SC,a TN, VT, VA, WV, DC). Percent regional coverage of AI/AN persons in Contract Health Service Delivery Area counties to AI/AN persons in all 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%.
