Harrison county is located in eastern Ohio with Cadiz serving as the county seat. The county population on July 1, 1999, was 16,070, a decrease of 15 over the 1990 census.
The county was formed in 1813 from portions of Jefferson and Tuscarawas counties and its economy originally was based on agriculture becoming a major wool-producing region in the late nineteenth century. An oil boom hit the county in the early 1900s, followed by a period of coal mining which remains an important component of the county's economy today.
Today, Harrison county's tourism industry plays an increasingly important role in the economy. It has rich tourism-related resources including several historically significant sites, more than 4,200 acres of public lakes, 20,000 acres of public land and over 100 miles of public hiking and bicycling routes.
