Rate per 100,000 persons of corresponding group. Rates for Alaska Native people were determined from the Indian Health Service (IHS) direct and contract health service inpatient dataset. Rates for the general US population used the Nationwide Inpatient Sample (NIS) to represent all of the US population. The 2007–2009 average annual regional populations for the Alaska Native people were as follows: Anchorage (57082), Barrow (4358), Yukon-Kuskokwim (24707), Bristol Bay (5277), Kotzebue (7038), Mt. Edgecumbe (15073), Norton Sound (8281), Interior Alaska (12959) and Annette Island (1415). Specific Interior Alaska and Annette Island regions are included in the overall analysis, but not presented individually due to non-reporting and small numbers.
