Marion County, South Carolina
Marion County is a rural Pee Dee county in northeastern South Carolina, bordered by Florence, Horry, Marlboro, and Dillon counties, and anchored by Marion, its seat, and Mullins, a former tobacco-market town to the south. The economy remains tied to agriculture and a shrinking manufacturing base, population has declined for decades, and real estate activity is limited to farmland, timberland, and modest in-town housing.
