Kenosha County is a county in the southeastern corner of the U.S. state of Wisconsin. Its population in 2018 was estimated to be 169,290, making it the eighth most populous county in Wisconsin. The county is named after the county seat, Kenosha, the fourth largest city in Wisconsin.
Kenosha County is part of the Chicago-Joliet-Naperville, IL-IN-WI Metropolitan Statistical Area. It is on the west shore of Lake Michigan. The county has traditionally attracted newcomers from suburban Chicago, and in March 2008 the demographers of the Wisconsin Department of Administration reported that Kenosha County's improvements in roads, business's need for personnel, and quality-of-life factors had contributed to a decades-long influx of Illinois transplants, along with the direct rail link to Chicago via Metra's Union Pacific / North Line.
The Potowatomi inhabited the area that would become Kenosha County for centuries prior to the acquisition of the area in 1833. The city of Kenosha was founded in 1835, and Kenosha County was formed from Racine County in 1850. Its location led to development and factories being built in the 19th century. Manufacturing continued to be a key component of the economy into the 20th century.
According to the U.S. Census Bureau, the county has a total area of 754 square miles (1,950 km2), of which 272 square miles (700 km2) is land and 482 square miles (1,250 km2) (64%) is water. Although the county contains area from Lake Michigan, it is the fourth-smallest county in Wisconsin by land area.
