By 2035, the population of Sioux Falls is projected to reach 233,000.

The Big Sioux River falls were created during the last ice age, and they have attracted many people to the land since then. Many indigenous peoples inhabited the area before Europeans arrived, including the Dakota, Nakota, Cheyenne, Quapaw, Kansa, and Missouri people. The high bluffs close to the river are still the site of several burial grounds from the region's early history.

French explorers were the first Europeans to arrive in the early 18th century. The first European American who visited was Philander Prescott in 1832. In 1856, the Dakota Land Company from St. Paul and the Western Town Company from Iowa organized to claim the land surrounding the falls. A temporary barricade was constructed called Fort Sod to respond to hostility from neighboring tribes. That first year, 17 men wintered in the region. The next year, Sioux Falls' population grew to 40.

In 1865, Fort Dakota was established in present-day downtown and a new wave of settlers came to the region. By 1873, the Village of Sioux Falls had 593 people. It was granted a city charter in 1883. The area experienced a large boom that decade as the railroads arrived and Sioux Falls' population grew from 2,100 in 1880 to more than 10,100 by 1890, although the growth slowed to a virtual standstill the next decade due to depression and a plague of grasshoppers.

By 1955, the city consolidated the neighboring city of South Sioux Falls, which had a population of 1,600. The population has proliferated since the 1970s, hitting 81,000 in 1980 and 153,000 in 2010.
