St. Clair County is part of the American Bottom or Metro-East area of the St. Louis, MO-IL Metropolitan Statistical Area. In 1970, the U.S. Census Bureau placed the mean center of U.S. population in St. Clair County.〔(【引用サイトリンク】title=Mean Center of Population for the United States: 1790 to 2000 )〕 ==History== St. Clair County was the first county established in what is today Illinois. In fact the county antedates Illinois' existence as a separate entity. It was established in 1790 by proclamation of Arthur St. Clair, first governor of the Northwest Territory, who named it after himself. In its original boundaries, St. Clair county covered a large area between the Mackinaw and Ohio Rivers. In 1801, Governor William Henry Harrison re-established St. Clair County as part of the Indiana Territory, extending its northern border to Lake Superior and the international border with Rupert's Land.〔White, Jesse. ''Origin and Evolution of Illinois Counties.'' State of Illinois, March 2010.
