Note: The percentage of the AI/AN population living in a PRCDA-designated county from 2013–2017 was 53.3% for the United States; by IHS region, these percentages were: Alaska = 100%; Pacific Coast = 60.3%; Southwest = 83.9%; Northern Plains = 54.3%; Southern Plains = 56.7%; and East = 16.8%.
Abbreviations: AI/AN, American Indian/Alaska Native; CI, confidence interval; IHS, Indian Health Service; N, number; PRCDA, Purchased/Referred Care Delivery Area; RR, rate ratio.
Analyses are limited to persons of non-Hispanic origin.
AI/AN race is reported by NPCR and SEER registries or through linkage with the IHS patient registration database.
Rates are per 100,000 persons and are age adjusted to the 2000 U.S. 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 table.
Indicates rate ratio is statistically significant (P < 0.05).

IHS regions are defined as follows: Alaska*; Northern Plains (IL, IN*, IA*, MI*, MN*, MT*, NE*, ND*, SD*, WI*, WY*); Southern Plains (OK*, KS*, TX*); Southwest (AZ*, CO*, NV*, NM*, UT*); Pacific Coast (CA*, ID*, OR*, WA*, HI); East (AL*, AR, CT*, DE, FL*, GA, KY, LA*, ME*, MD, MA*, MS*, MO, NH, NJ, NY*, NC*, OH, PA*, RI*, SC*, TN, VT, VA*, WV, DC); * identifies states with at least one county designated as PRCDA.
