County Data for Warren County, Ohio

Warren County is a county located in the state of Ohio, United States. The population was 158,383 at the 2000 census. The Census estimate for July 1, 2006, was 201,861 making Warren County the second fastest growing county in Ohio and 80th in the United States. Its county seat is Lebanon. Warren County was erected May 1, 1803, from Hamilton County, and named for Dr. Joseph Warren, a hero of the Revolution who sent Paul Revere on his ride and who died at the Battle of Bunker Hill.

Warren County is part of the Cincinnati–Middletown, OH-KY-IN Metropolitan Statistical Area.


According to the U. S. Census Bureau, the county has a total area of 407 square miles (1,054 km²). 400 square miles (1,035 km²) of it is land and 8 square miles (19 km²) of it (1. 84%) is water. The county is a rough square with the sides roughly 20 miles (30 km) long.

Adjacent counties

Beginning in the northwest corner and proceeding clockwise, the following counties border Warren County: Montgomery, Greene, Clinton, Clermont, Hamilton, and Butler.


Warren County was created by the first Ohio General Assembly in the Act of March 24, 1803, which also created Butler and Montgomery Counties. The act defined Warren County as "all that part of the county of Hamilton included within the following bounds, viz. : Beginning at the northeast corner of the county of Clermont, running thence west with the line of said county to the Little Miami; thence up the same with the meanders thereof to the north boundary of the first tier of sections in the second entire range of townships in the Miami Purchase; thence west to the northeast corner of Section No. 7 in the third township of the aforesaid range; thence north to the Great Miami; thence up the same to the middle of the fifth range of townships; thence east to the County line; thence with same south to the place of beginning. " Originally this included land now in Clinton County as far east as Wilmington.

Clinton County proved a continuing headache to the legislature. The Ohio Constitution requires that every county have an area of at least four hundred square miles (1,036 km²). Clinton County's boundaries were several times adjusted in an effort to comply with that clause of the constitution. One of them, the Act of January 30, 1815, detached a strip of land from the eastern side to give to Clinton. That would have left Warren under four hundred square miles (1,036 km²), so a portion of Butler County (the part of Franklin Township where Carlisle is now located) was attached to Warren in compensation. The 1815 act was as follows:

  • Section 1—That all that part of the county of Butler lying and being within the first and second fractional townships in the fifth range, and adjoining the south line of Montgomery County, shall be and the same is hereby attached to and made part of the county of Warren.
  • Section 2—That eleven square miles 28 km² of the territory of the county of Warren and extending parallel to the said eastern boundary of Warren County, along the whole length of such eastern boundary from north to south, shall be and the same is hereby attached to and made a part of the county of Clinton. "
  • Except for the sections formed by the Great and Little Miamis, the sides are all straight lines.

    Warren County is staunchly Republican and has been since the party was established in the 1850s. Since the first presidential election after its founding, 1856, Warren County has supported the Republican candidate for president all but once, the exception being 1964 when Warren County voted for Democrat Lyndon B. Johnson over Barry M. Goldwater. Before the Republican party was formed, Warren County supported the Whigs. Since 1869, Warren County has almost always supported the Republican candidate for Governor of Ohio, the exceptions being in 1924 when it supported Vic Donahey, 1932 (George White), 1952 (Frank Lausche), and 1958 (Michael V. DiSalle). However, excepting DiSalle, each of these four Democrats, who were all victorious statewide, was a conservative Democrat.

    In local races, Warren County occasionally elected Democrats. In 1976, two of the three county commission seats were won by Democrats. Until the mid-1990s, Democrats regularly ran for county offices and, while almost always losing, did not do so badly. However, with the massive expansion in population in the 1990s, the county became extremely Republican, so much so the Democrats fail to field any candidates. In the 1996, 2000, and 2004 elections, in which eight county offices were on the ballot, there were no Democratic candidates for any of them. In November 1999, the last Democrat to hold office in Warren County, a member of the Educational Service Center (county school board), lost her seat to a Republican.
