This is not true, in my experience, in rural Indiana. I hear the n word a lot for an area that I have yet to meet a black person. One neighbor was complaining about the California family that moved to town and brought all the drug problems with them, despite our county having been the meth capital of Indiana for years before they moved here. Somehow my first conversation with a friend's mom I met while visiting their rural farm involved how there were no black people in the area. But this is why all anecdotal data should be taken with a grain of salt.
