well its one of the only ethnicities that your tiny %age doesn't mean squat, and you cant claim it.
the federal government backs a certain % depending on the tribe. to be legit native relation.
my tribe requires at least 25% (im 44 :D)
on the reservation, they all call themselves indian. ive never seen anyone from my tribe to give a forget about the political correct terms.
some of em even call white people "pilgrims" as kind of an ironic joke.
