Davenport is the county seat of Scott County in Iowa and is located along the Mississippi River on the eastern border of the state. It is the largest of the Quad Cities, a metropolitan area with a population estimate of 382,630 and a CSA population of 474,226; it is the 90th largest CSA in the nation. Davenport was founded on May 14, 1836 by Antoine Le Claire and was named for his friend, George Davenport, a colonel who was stationed at nearby Fort Armstrong during the Black Hawk War. According to the 2010 census, the city had a population of 99,685. The city appealed this figure, arguing that the Census Bureau missed a section of residents, and that its total population was more than 100,000. The Census Bureau estimated Davenport's 2011 population to be 100,802.Located approximately halfway between Chicago and Des Moines, Davenport is on the border of Iowa across the river from Illinois. The city is prone to frequent flooding due to its location on the Mississippi River.
