Sioux City is a city in Woodbury and Plymouth counties in the northwestern part of the U.S. state of Iowa. The population was 82,684 in the 2010 census, which makes it the fourth largest city in Iowa. The bulk of the city is in Woodbury County, of which it is the county seat, though a small portion is in Plymouth County. Sioux City is located at the navigational head of the Missouri River. Often the city and surrounding area is referred to as Siouxland, especially by the local media and residents. The city is home to several cultural points of interest including the Sioux City Public Museum, Sioux City Art Center and Sergeant Floyd Monument, which is a National Historical Landmark. The city is also home to Chris Larsen Park, commonly referred to as "the Riverfront," includes the Anderson Dance Pavilion, Sergeant Floyd Riverboat Museum and Lewis and Clark Interpretive Center. Sioux City is the primary city of the five-county Sioux City, IA-NE-SD Metropolitan Statistical Area (MSA), with a population of 168,825 in 2010 and a slight increase to an estimated 168,921 in 2012. The Sioux City-Vermillion, IA-NE-SD Combined Statistical Area had a population of 182,675 as of 2010 and has grown to an estimated population of 183,052 as of 2012.
Sioux City is at the navigational head, or the most upstream point to which general cargo ships can travel, of the Missouri River, about 95 miles north of the Omaha-Council Bluffs metropolitan area. Sioux City and the surrounding areas of northwestern Iowa, northeastern Nebraska and southeastern South Dakota are sometimes referred to as Siouxland, especially by the local media.
Iowa is in the tallgrass prairie of the North American Great Plains, historically inhabited by speakers of Siouan languages. The area of Sioux City was inhabited by Yankton Sioux when it was first reached by Spanish and French furtrappers in the 18th century. The first documented US citizens to record their travels through this area were Meriwether Lewis and William Clark during the summer of 1804. Sergeant Charles Floyd, a member of the Lewis and Clark Expedition, died here on August 20, 1804, the only death during the two and a half-year expedition.
1859 map of route from Sioux City, Iowa, through Nebraska, to gold fields of Wyoming, partially following old Mormon trails.
Sioux City was laid out in the winter of 1854-55. It became a major Entrepôt to the western Plains, including Mormons heading to Salt Lake City and speculators heading to Wyoming gold fields.
In 1891, the Sioux City Elevated Railway was opened and became the third steam powered elevated rapid transit system in the world, and later the first electric-powered elevated railway in the world after a conversion in 1892. However, the system fell into bankruptcy and closed within a decade.
The city gained the nickname "Little Chicago" during the Prohibition era due to its reputation for being a purveyor of alcoholic beverages.
On July 19, 1989, United Airlines Flight 232 crash landed at Sioux Gateway Airport, killing 111 people, but 184 survived the crash and ensuing fire due to outstandingly quick performances by fire and emergency local teams that earned them several National Congress Medals, given by President George H. W. Bush in 1990.
