Sioux Falls takes its name from the falls of the Big Sioux River, which drew the first town developers in the mid-1850s. Land speculators saw both the scenery and the water power of the falls, and they moved to claim the site ahead of the railroads and settlers. Early conflict led to the settlement being abandoned in 1862, but a military post, Fort Dakota, brought people back in 1865.
The city's growth accelerated when the railroad arrived in 1878. That connection set off the Great Dakota Boom of the 1880s, tripling the population and turning an isolated settlement into the trade center of the region. South Dakota gained statehood in 1889.
Sioux Falls is a young, growing city and the population center of South Dakota. The city has added residents faster than the state as a whole, and the broader metro area continues to expand across four counties in South Dakota and one in Minnesota. The median age sits in the mid-30s, which reflects a strong base of working families.

The economy leans on a few large sectors, with health care as the clear leader.
