The 4th Congressional District of Georgia was created in December 1995 when a three-judge federal panel issued a map that dismantled two of the state's three majority-black districts drawn after the 1990 census. Under the new map, the 4th Congressional District encompasses most of DeKalb County and the southwest portion of Gwinnett County.
The district buttresses the City of Atlanta proper on the eastern border of the city. 87% of the district's population live in DeKalb County. Incorporated cities in DeKalb
County are:
Doraville
Chamblee
Clarkston
Decatur
Avondale Estates
Pine Lake
Stone Mountain
Lithonia
Unincorporated DeKalb County makes up the largest land parcel of the 4th District. A portion of Gwinnett County (Southwestern Gwinnett) is included in the district. The incorporated municipalities of Gwinnett County include Berkeley Lake and Norcross. The nothern most city limit of the city of Berkeley Lake marks the northern most border of the district in Gwinnett County. The district swings East and South over to, but does not including the City of Lilburn. Specifically, from the DeKalb-Gwinnett line on the north, the boundary follows Jones Mill Road up Crooked Creek to Holcomlb Bridge Road. The border takes a southerly turn following Highway 141 and up the Chattahoochee River around Berkeley Lake city limits to Gravitt Road. From Gravitt Road the boundary follows Old Norcross Road, Liddell Road south to Bromolow Creek to Beaver Ruin Creek and out onto Beaver Ruin Road to Burns Drive. Taking a westerly direction the boundary follows Dickens Road to Harbins Road, Williams Road to Rockbridge Road south to Jackson Creek. From Jackson Creek the border goes into Luckie Shoals Creek to the DeKalb County line just northeast of Tucker, Georgia.
