Sioux Falls | USA South Dakota

Sioux Falls is an independent city and the seat of Minnehaha County, situated on the Big Sioux River. It is the largest city in South Dakota and is defined by its role as a regional financial powerhouse, its absence of state corporate and personal income taxes, and its status as a critical healthcare and retail hub for the upper Great Plains.

Historical Timeline

Inhabited by the Ho-Chunk, Ioway, Otoe, and later Lakota Sioux. Founded in 1856 near the cascades of the Big Sioux River. A critical historical event occurred in 1862 when the settlement was abandoned during the Dakota War, only to be resettled with the 1865 establishment of Fort Dakota. In the 20th century, the city transitioned from a meatpacking center (John Morrell & Co.) into a financial hub following the 1981 relocation of Citibank’s credit card operations. In the 21st century, it has experienced explosive growth, consistently ranking among the fastest-growing mid-sized cities in the U.S. due to its favorable business climate.

Demographics & Population

The 2026 population is approximately 215,000 (Metro area ~300,000). The demographics are White (80%), Black or African American (7%), and Hispanic or Latino (6%). The city has a growing immigrant and refugee population. The economy is driven by Financial Services (banking and credit cards), Healthcare (Sanford Health and Avera Health), and retail.

Facts & Legends

Sioux Falls is home to more bank assets than almost any other city in the U.S. per capita due to its credit card laws. Historically, the city’s buildings are unique for the use of Sioux Quartzite, a local stone that is harder than granite and naturally pink. A local legend involves the "Gitchie Manitou" site, rumored to be haunted by spirits from ancient conflicts. Another legend concerns the "Secret Underground Tunnels" built during the late 19th century to connect downtown businesses and transport coal.
