As of 2000, Iredell County's population was 122,660. Its county seat is Statesville.
It is a major hub of NASCAR racing, with many race shops located in the county (mostly around Mooresville). NASCAR also operates the NASCAR Technical Institute Universal Technical Institute operates NASCAR Tech under licensing agreements. The school offers racing-related instruction to prepare the student for their job search in the racing industry. Many NASCAR drivers live around Mooresville and Lake Norman. Although northern Iredell County has retained much of its rural character, the southern half of the county is experiencing rapid suburbanization and population growth, largely due to the immense popularity of the Lake Norman area for residents of nearby Charlotte, North Carolina's largest city.
Iredell County is an important transportation center for the state, as both Interstate 77 and Interstate 40 cross just north of Statesville. This has given birth to the county's slogan "Crossroads for the Future." Residents have easy access south down I-77 to Charlotte, North Carolina, north to Elkin, North Carolina, and Roanoke, Virginia, east to Winston-Salem and Greensboro, and west along I-40 to Hickory, North Carolina, and Asheville.
Farming is still a major source of income for many Iredell County residents. Dairy farming has been particularly popular in Iredell County for centuries, in both the northern and southern sections of the county. However, the rapid population growth and development in southern Iredell County is putting increasing pressure on farmlands, and many farms in this section are giving way to shopping centers, housing developments, and large corporate office parks.
