South Dakota became the 40th state on November 2, 1889. Its civic life reflects Lakota, Dakota, and Nakota nations, agriculture, tourism, public lands, the Black Hills, small towns, and rural service challenges. Public decisions about schools, health care, roads, tribal-state relations, water, emergency services, and land use often turn on distance, local capacity, and history. Use this profile to orient yourself to South Dakota representation and official resources while recognizing that public services and representation can feel very different across the state’s communities.
