I'm curious how carefully these things are checked. Like many white people with ancestors from Appalachia, I'm sure I'm at least slightly Native American. Is it fair to mark Native American (and white?) on these forms?
the federal definition of "American Indian or Alaska Native" is "A person having origins in any of the original peoples of North and South America (including Central America), and who maintains tribal affiliation or community attachment." In other words, if you don't have community attachment to an Indian tribe, or formal legally recognized tribal membership, you are not a Native American or Alaska Native.
