Kansas County Data
Select a County Site to visit:

Jefferson County is located in northeast Kansas. It was one of the thirty-three counties created by the territorial legislature held at the Shawnee Manual Labor School August 25, 1855. Jefferson County was named in honor of Thomas Jefferson, the author of the Declaration of Independence and the third president of the United States. The county seat was originally established in Ozawkie and was later moved to Oskaloosa. The Jefferson County Courthouse was built in the center of the Oskaloosa town square in 1867. It was destroyed by a tornado in May 1960. At the time of the tornado, it was the oldest courthouse in the State of Kansas. In 1962, Jefferson County occupied a new courthouse built on the same location.

Jefferson County terrain is rolling and hilly; where there are streams or rivers you find trees and bushes growing on their banks. “The Kaw” or Kansas River forms the southern boundary of the County, but the largest river in Jefferson County is the Delaware (originally called the Grasshopper River). The Delaware River is a major tributary of the Kansas River. When they built the dam that formed Perry Lake it inundated the original town of Ozawkie. They rebuilt the town on higher ground to the west of the original location.

In 1860 Jefferson County had a population of 4,459. The people have always earned their living in agriculture and that’s why, one hundred and fifty years later, the population had only increased to 19,126. More on Jefferson County.
