Note. AI/AN = American Indians/Alaska Natives; CHSDA = Contract Health Service Delivery Areas; CI = confidence interval; IHS = Indian Health Service; NPCR = National Program of Cancer Registries; RR = rate ratio; SEER = Surveillance, Epidemiology, and End Results program. Dashes indicate that counts < 6 are suppressed; if no cases reported, then rates and RRs could not be calculated. RRs were calculated in SEER*Stat before rounding of rates and may not equal RRs calculated from rates presented in table. Analyses are limited to persons of non-Hispanic origin. Rates are per 100 000 persons and were age adjusted to the 2000 US standard population (11 age groups; Census P25-1130). AI/AN race is reported by NPCR and SEER registries or through linkage with the IHS patient registration database. Percent regional coverage of AI/AN persons in CHSDA 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%. IHS 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). Cancer causes of death were created using the SEER cause of death recode.
