What was the fifth most populated area in the Confederacy in late-1864?

I will guess the Andersonville Prison area (Macon County, GA) ???

By 1864, Andersonville Prison was holding the largest prison population of its time (which I believe was due to the halt of the prisoner exchange??) If memory serves me correctly, I remember reading that by 1864, some 1,000 men died daily at Andersonville from either starvation or disease.
