Kernersville is a town in Forsyth County in the U.S. state of North Carolina. The population was 17,126 at the 2000 census. In 2007 the U.S. Census estimated the town's population at 22,309. Kernersville is located at the heart of the Piedmont Triad metropolitan area, which consists of the cities of Greensboro, High Point, and Winston-Salem. Although Kernersville has traditionally been considered a suburb of Winston-Salem, the arrival of new industries (particularly the Dell Computer plant), has given the city a booming population and a character all its own. Much of the rural farmland surrounding the town has been sold and turned into large middle-to-upper-class housing developments, and numerous large shopping centers have been built in the town over the past few years. Flue-cured tobacco was the major crop grown in the area.
