There is a small but sizable minority of Hispanic people moving to the area yet not enough for a knowledge of the Spanish language would be required. The Oglala Lakota are a prominent Native American tribe in the region so you may be inclined to know some of their language and customs if you plan on visiting Pine Ridge. Also, at one time there was a large influx of Scandinavian and German immigrants to the region, though extremely uncommon there are still some areas that have elderly speakers of their native tongue.
