CHSDA indicates Contract Health Service Delivery Areas; IHS, Indian Health Service; AI/AN, American Indians/Alaska Natives; NHW, non-Hispanic whites; CI, confidence interval.
AI/AN race is reported by NPCR and SEER registries or through linkage with the IHS patient registration database. AI/AN persons of Hispanic origin are included.
Rates are per 100,000 persons and are age-adjusted to the 2000 US standard population (19 age groups, Census P25-1130).
Rate ratios are calculated in SEER*Stat prior to rounding of rates and may not equal rate ratios calculated from rates presented in the table.
Rate ratio is statistically significant (P <.05).
Rates and rate ratios for Alaska in the CHSDA counties section are the same as those in the All Counties section because all counties in Alaska are CHSDA counties.
