The Gwinnett County Georgia map covers a major suburban county northeast of Atlanta. Lawrenceville is the county seat, but a network of seventeen municipalities and extensive unincorporated neighborhoods distributes population, employment, schools, shopping, and cultural activity across the county.
The U.S. Census Bureau estimated 1,018,099 residents on July 1, 2025, a 6.3 percent increase from the 2020 estimates base. The 2020 census counted 957,062 residents, compared with 805,321 in 2010.

From an Agrarian County to a Metropolitan Center
Gwinnett County was created on December 15, 1818, from part of Jackson County and land ceded by Creek and Cherokee peoples. It was named for Button Gwinnett, one of Georgia’s signers of the Declaration of Independence.
The county remained largely agricultural through the nineteenth and early twentieth centuries. Rapid highway construction, Atlanta’s outward growth, business investment, and large-scale residential development transformed it after 1970.
Map Coverage and File Options
This Gwinnett County Georgia map set contains color, black-and-white, and outline A3 JPG files. The labeled versions support regional reference, while the outline version provides room for municipal, transportation, demographic, or environmental information.
Gwinnett County currently lists seventeen municipalities, including the recently created City of Mulberry. Because no finished source image was supplied, the article does not claim that every municipality appears on every labeled map.
Lawrenceville and the County Government Core
Lawrenceville was incorporated and designated the county seat in 1821. Its courthouse square, government campus, hospital services, schools, businesses, and cultural facilities make it the central administrative city.
Georgia Highway 316 connects Lawrenceville with Athens, while local roads link it with Interstate 85 and the surrounding municipalities. The city combines an older downtown with industrial parks, suburban neighborhoods, and newer mixed-use development.
Railroads and the Founding of Northern Cities
A major railroad reached the county in 1871 and encouraged the development of Norcross, Duluth, Suwanee, and Buford. A later line supported Lilburn, Lawrenceville, and Dacula.
These former rail towns now serve different metropolitan roles. Norcross and Duluth have international business districts, Suwanee emphasizes parks and planned growth, and Buford combines industry, retail, and access to the Lake Lanier area.
Interstate 85, Technology, and Employment
Interstate 85 is the county’s primary regional corridor. Peachtree Corners, Norcross, Duluth, and nearby unincorporated districts contain technology firms, offices, warehouses, hotels, retail centers, and dense residential development.
Interstate 985 begins near the northern county and continues toward Gainesville. Georgia 316 provides an eastward route toward Athens, making Gwinnett a gateway between metropolitan Atlanta and northeastern Georgia.
Seventeen Municipalities and Large Unincorporated Areas
- Lawrenceville is the county seat and government center.
- Peachtree Corners is a western technology and employment center.
- Snellville and Grayson anchor growing southeastern residential areas.
- Sugar Hill, Suwanee, and Buford serve the northern corridor.
- Mulberry is the county’s newest municipality.
Most county residents historically lived outside incorporated city limits. Centerville and many other named communities remain unincorporated, so postal addresses, school zones, service areas, and municipal boundaries do not always match.
Diversity and Regional Identity
Gwinnett grew from 72,349 residents in 1970 to more than one million by the middle of the 2020s. Immigration and domestic migration created highly diverse neighborhoods, schools, religious institutions, restaurants, and commercial districts.
The county is no longer simply a bedroom suburb. Manufacturing, logistics, health care, education, technology, professional services, retail, and entertainment support a large local employment base.
