Unincorporated areaAn unincorporated area is a region that is not governed by a local municipal corporation. Widespread unincorporated communities and areas are a feature of the United States and Canada. Most other countries of the world either have no unincorporated areas at all or these are very rare. In Argentina, the provinces of Chubut, Córdoba, Entre Ríos, Formosa, Neuquén, Río Negro, San Luis, Santa Cruz, Santiago del Estero, Tierra del Fuego, and Tucumán have areas that are outside any municipality or commune.
