Alaska Native Village Statistical Areas are geographical areas the United States Census Bureau uses to track demographic data. These statistical areas represent permanent or seasonal residences of Alaska natives. Specifically, they contain a significant proportion of persons who are either member of, or receiving services from a defining Alaska Native Village for at least one season of the year. Alaska Natives previously had many small reserves scattered around Alaska; however, all but one were repealed with the passage of the Alaska Native Claims Settlement Act in 1971.
State Designated Tribal Statistical Areas are geographical areas the United States Census Bureau uses to track demographic data. These areas have a substantial concentration of members of tribes that are State recognized but not Federally recognized and do not have a reservation or off-reservation trust land.
