Clayton County

Clayton County was formed in 1858 out of portions of Fayette and Henry counties. It was named after Judge Augustin S. Clayton, who served in the Georgia General Assembly.

Notable landmarks include Clayton State University, Spivey Hall, the National Archives at Atlanta and Reynolds Nature Preserve. Large employers include Delta TechOps, Southern Regional Medical Center and Fresh Express.

Clayton’s population, relatively flat in the years following the financial crisis, is growing as the county’s economy strengthens. At 143 square miles, Clayton is the third-smallest county in the state and the second-smallest in the 10-county region, larger only than Rockdale County.

Within Clayton County are the cites of College Park*, Forest Park, Jonesboro, Lake City, Lovejoy, Morrow, and Riverdale.
