The Blue Ridge Mountain Region of Georgia (encompassing counties like Fannin, Gilmer, Union, Towns, Rabun, and parts of others) has an estimated population of ~1.2 million people (per recent census/Wikipedia data).
The region includes small cities such as Blue Ridge, Ellijay, Blairsville, Hiawassee, and Clayton, plus extensive rural and forested areas. Population growth has been steady due to retirement migration, tourism development, and exurban expansion from Atlanta.
