Woodbury County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 105,941,[2] making it the sixth-most populous county in Iowa. The county seat is Sioux City.[3]

Woodbury County is included in the Sioux City metropolitan area.[4]

History[edit]

Originally established in 1851 as Wahkaw County, the Iowa Legislature in 1853 changed the name to Woodbury County in honor of Levi Woodbury (1789–1851), a senator and governor of New Hampshire who served as a Supreme Court justice from 1844 until his death.

The first county seat of Wahkaw County was the now-extinct village of Thompsonville; when the Legislature changed the county name to Woodbury, the new county seat became Sergeant's Bluff (now Sergeant Bluff). The county seat was moved to Sioux City in 1856.

The Winnebago Tribe of Nebraska (Ho-Chunk) owns reservation land in Woodbury County.

Geography[edit]

The county is on the western edge of Iowa, with its western border being the Missouri River.

According to the U.S. Census Bureau, the county has a total area of 878 square miles (2,270 km2), of which 873 square miles (2,260 km2) is land and 4.9 square miles (13 km2) (0.6%) is water.[5] It is the third-largest county by area in Iowa.

Politics[edit]

For much of the second half of the 20th century, Woodbury County tilted Republican, albeit not as overwhelmingly as most of western Iowa. Between 1988 and 2012 Woodbury County was the quintessential swing county in Iowa. No candidate won it by more than 3.5% over that quarter-century. This was the only county in Iowa that Barack Obama won in 2012 that he failed to carry in 2008. However, in 2016, Woodbury County swung over dramatically to Donald Trump, who carried it by a 22 percent margin, the largest margin of victory since Lyndon Johnson's landslide election in 1964.
