Columbia County, Georgia
Columbia County covers 290 square miles on Augusta's western edge with roughly 162,400 residents in Evans, Martinez, Grovetown and Harlem. Fort Eisenhower and the Army's cyber command drive demand, giving the county a steady inflow of relocating military and contractor households. Its schools are the other draw and the reason its values sit well above Richmond County's next door. Median home value is $305,300 against median household income of $96,000.
