Here are the Charlotte area urbanized areas and urban clusters.
Counties with at least 50% of their population in an urbanized area qualify as central counties of a metropolitan statistical area. Because of the expansion of the Charlotte urbanized area to include Mooresville and Statesville, Iredell County will be a central county along with Mecklenburg and Union. Other counties qualify as outlying based on communting to those counties. Gaston, York, Cabarrus, Rowan, Anson, and possibly Lincoln, Stanly, and Lancaster could be in the metropolitan area once the new delineations are announced next year.
