The area was very sparsely populated even before the white immigrants, which is mainly due to unfavorable geographical and climatic factors. The currently around 12,000 Native Americans in Wyoming mainly belong to the two tribes of the Cheyenne and Arapaho. Almost the entire indigenous population lives in the state’s only reservation in the western center, in the Wind River Indian Reservation, which is the seventh largest reservation in the USA with an area of 9148 km².
