The Diné (Navajo) Nation has the largest contemporary contiguous land base among Native nations: nearly sixteen million acres, or nearly twenty-five thousand square miles, the size of West Virginia. Each of twelve other reservations is larger than Rhode Island, which comprises nearly eight hundred thousand acres, or twelve hundred square miles, and each of nine other reservations is larger than Delaware, which covers nearly a million and a half acres, ore two thousand square miles. Other reservations have land bases of fewer than thirty-two thousand acres, or fifty square miles. A number of independent nation-states with seats in the United Nations have less territory and smaller populations than some Indigenous nations of North America.
