Looking at their distribution, you can see Native American concentrations in modern tribal areas — Oklahoma, in particular, is easy to pick out. Other reservations and concentrations of Native Americans can be seen in the southwest, and parts of the northern Great Plains.
Native American demographics weren’t included in the census dataset I used as my primary source. They’re included in files that look at race, rather than ancestry, and it’s a little weird to me that the two aren’t kept together. Race is about more than just race – it’s also about where we came from, and how we got where we are today. These maps help show both where we are now, and to some extent, I think they speak to how we got here, as well.
