Although the American Indian Population and Labor Force Report is federally mandated to be released no less frequently than biennally, the last report was released in 2007, with figures based on 2005. However, an updated report is supposed to be released this year.
These figures are based on tribes in the lower 48 states, only, who have at least 1,000 tribal members, of which at least 500 are unemployed. According to the 2005 figures, fifteen tribes have staggering unemployment rates exceeding 80%.
