Jefferson County is a county located in the U.S. state of Ohio. As of the 2010 census, the population was 69.709.〔(【引用サイトリンク】url=http://quickfacts.census.gov/qfd/states/39/39081.html )〕 Its county seat is Steubenville.〔(【引用サイトリンク】accessdate=2011-06-07 )〕 The county is named for Thomas Jefferson, who was at the time Vice President. Jefferson County is part of the Weirton-Steubenville, WV-OH Micropolitan Statistical Area, which is also included in the Pittsburgh-New Castle-Weirton, PA-WV-OH Combined Statistical Area.〔http://www.whitehouse.gov/sites/default/files/omb/bulletins/2013/b13-01.pdf〕 ==History== Jefferson County was organized on July 29, 1797 by proclamation of Governor Arthur St. Clair, six years before Ohio was granted statehood. In 1786, the United States built Fort Steuben to protect the government surveyors mapping the land west of the Ohio River. When the surveyors completed their task a few years later, the fort was abandoned. In the meantime, settlers had built homes around the fort; they named their settlement La Belle. When the County was created in 1797, La Belle was selected as the County seat. The town was subsequently renamed Steubenville, in honor of the abandoned fort. During the first half of the nineteenth century, Steubenville was primarily a port town, and the rest of the county consisted of small villages and farms. However, in 1856, Frazier, Kilgore and Company erected a rolling mill (the forerunner of steel mills) and the Steubenville Coal and Mining Company sank a coal shaft, resulting in Jefferson County becoming one of the leading centers of the new Industrial Revolution. Jefferson County's population has declined to 70% of its 1960 figure as its manufacturing base collapsed over the last few decades. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jefferson County, Ohio」の詳細全文を読む スポンサード リンク
