Gwinnett County, Georgia

Gwinnett County is the second most populous county in the State of Georgia, with an estimated population of approximately 960,000 residents. Located in the northeastern quadrant of the Atlanta metropolitan area, Gwinnett has undergone one of the most dramatic demographic and economic transformations of any county in the United States over the past four decades. What was a predominantly rural, white county of approximately 72,000 residents in 1970 has become one of the most ethnically diverse counties in the southeastern United States, where no single racial or ethnic group constitutes a majority and where more than 150 languages are spoken in the public school system.

Geography and Physical Setting

Gwinnett County encompasses approximately 437 square miles of gently rolling Piedmont terrain in the northeastern portion of Metro Atlanta. The county is bounded by Forsyth and Hall counties to the north, Barrow and Walton counties to the east, Rockdale and DeKalb counties to the south, and Fulton County to the west. The Chattahoochee River forms a portion of the western boundary, and Lake Sidney Lanier extends into the northern portion of the county. Elevations range from approximately 800 to 1,200 feet above sea level, and the landscape transitions from densely developed suburban communities in the south and west to more rural and recently developed areas in the north and east.

Major transportation corridors include Interstate 85 (which crosses the county diagonally from southwest to northeast), Interstate 985/Georgia 365 (which begins in the northern portion of the county and extends toward Gainesville), and State Route 316 (providing access to Athens). These highways, combined with an extensive network of state routes and county roads, provide connectivity to downtown Atlanta (approximately 30 miles southwest) and to the surrounding metro counties.

Population and Demographics

Gwinnett County's population growth has been extraordinary by any measure. The county grew from approximately 72,000 in 1970 to 352,000 in 1990, 588,000 in 2000, 805,000 in 2010, and approximately 960,000 by the most recent estimates. This growth trajectory has made Gwinnett one of the fastest-growing counties in the United States over a sustained period and has required massive investment in schools, roads, water and sewer infrastructure, parks, and public services.

More notable than the growth rate has been the demographic transformation. Gwinnett County has been recognized by demographic researchers as the most ethnically diverse county in the southeastern United States. The county's population is approximately 30 percent white (non-Hispanic), 30 percent Black or African American, 22 percent Hispanic or Latino, and 13 percent Asian, with the remainder identifying as multiracial or other categories. The Asian population includes significant Korean, Vietnamese, Chinese, Indian, and Filipino communities. The Hispanic population includes substantial communities from Mexico, Guatemala, Honduras, Colombia, and other Latin American nations.

This diversity is reflected in the county's commercial landscape -- ethnic shopping centers, international grocery stores, restaurants representing dozens of cuisines, and religious institutions serving communities from around the world are found throughout the county. Buford Highway and Pleasant Hill Road corridors are particularly notable for their concentration of international businesses and restaurants. Gwinnett County Public Schools, one of the largest school districts in the nation with approximately 180,000 students, operates programs in English as a Second Language serving students who speak more than 150 languages.

Economy and Major Industries

Gwinnett County's economy is diversified across technology, healthcare, logistics, retail, small business, and professional services.

Major employers include Gwinnett Medical Center (now Northside Hospital Gwinnett), Georgia Gwinnett College, the Gwinnett County school system, and numerous technology and professional services firms.

The county's diverse population has spawned a vibrant small business economy, with immigrant entrepreneurs operating businesses across virtually every industry sector. International business corridors, particularly along Buford Highway and in the Pleasant Hill Road area, have created commercial districts with an international character unusual for suburban America.
