Champaign County derives its name from the character of its surface. A French word meaning level or flat...half its area being level or slightly undulating, one quarter rolling, twenty percent hilly and five percent prairie flat. There are more than 36,000 people sprinkled over the 276,480 acres that comprise the rural areas. Boundaries measure approximately 28 miles east to west and 16.5 miles north to south.

Of Ohio's 88 counties, Champaign became the 18th, when by legislative action it was carved from Greene and Franklin counties on March 1, 1805. It was March 1, 1817 that Champaign County took its present boundaries when both Logan and Clark counties were formed.


About OSU Extension

Since 1914, Extension has been helping all Ohioans build better lives, better businesses and better communities.

Ohio State University Extension brings the knowledge of the university directly to you. We fulfill the land-grant mission of The Ohio State University by interpreting knowledge and research developed by Extension and other faculty and staff at the Ohio Agricultural Research and Development Center, Ohio State main campus, and other land-grant universities – so Ohioans can use the scientifically-based information to better their lives, businesses and communities.

The Extension system is the world’s largest non-formal educational system. Extension programs address the needs of the local community while also addressing state, national, and global issues. Our practical educational programs combine the needs of local citizens and communities with new research and technical information.

No matter which county you visit, you can find people who are helped by the four major OSU Extension program areas: family and consumer sciences, 4-H youth development, community development, and agriculture and natural resources. These program areas – and many other special topics – are continuously evaluated and updated to meet the changing needs and issues facing each community. Extension provides practical advice, sensible solutions, and realistic down-to-earth answers for ALL Ohioans.
