The Census Bureau will release the "American Indian and Alaska Native Summary File (AIANSF)". This dataset will include for a total of 1,570 different indigenous nations and will be the largest data set for all of the American Indian and Alaska Native geographies that meet the population threshold of 100 people from the 2010 Decennial Census. There are going to be 70 tables of varying detail and subject matter for most of these geographies.
The data will be available on Thursday December 13 at 12:01 a.m at www.census.gov. There will be no additional releases of AIAN data from the Decennial 2010 Census.
