A planned community, or planned city, is any community that was carefully planned from its inception and is typically constructed in a previously undeveloped area. This contrasts with settlements that evolve in a more ad hoc fashion. Land use conflicts are less frequent in planned communities since they are planned carefully. The term new town refers to planned communities of the new towns movement in particular, mainly in the United Kingdom. It was also common in the European colonization of the Americas to build according to a plan either on fresh ground or on the ruins of earlier Amerindian cities.
