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: AK^a; Northern Plains (IL, IN,^a IA,^a MI,^a MN,^a MT,^a NE,^a ND,^a SD,^a WI,^a WY^a); Southern Plains (OK,^a KS,^a TX^a); Southwest (AZ,^a CO,^a NV,^a NM,^a UT^a); 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.
