Located in the south-central region of the United States, Oklahoma is the American state with the second largest Native American population in the country. The state is limited to the states of Colorado and Kansas to the north, Missouri and Arkansas to the east, Texas to the south, and Texas and New Mexico to the west.
Oklahoma became the 46th American state on November 16, 1907. Its name comes from the words “okla” and “humma”, which in the language of the Native American Croctaw mean “red people”. Although it has small mountain ranges, most of the state is marked by the presence of large prairies. Oklahoma has different types of habitats, a fact that allows great biodiversity to exist.
