Des Moines County is part of the Burlington, IA–IL Micropolitan Statistical Area.
Des Moines County should not be confused with the city of Des Moines, which is the capital of Iowa. Des Moines County sits on Iowa's eastern border alongside the Mississippi River. The city of Des Moines is in Polk County in central Iowa. Both places derive their name from the Des Moines River, which flows through the city of Des Moines and originally flowed through the county. When the county was divided early in Iowa's history, the river ended up further west, forming the border between Lee County, Iowa and the state of Missouri.
