Oklahoma is of American origin, derived from the Choctaw words "okla" meaning red and "humma" meaning people, thus translating to 'red people'. It's a unique name often associated with the state of Oklahoma in the United States, which was named after this combination of Native American words. The name Oklahoma gained popularity during the Land Run of 1889 when the Unassigned Lands were opened for settlement by non-Natives.
"The birth rate for the state of Oklahoma was quite low in its inaugural year, with only five newborns recorded in all of 1907."
