Urban Settlements

Urban settlements are permanent, relatively large, and densely populated places in which most residents depend on non-agricultural activities such as trade, manufacturing, administration, and services. They range from towns and cities to metropolitan regions and megacities, and definitions vary between countries according to population size, density, administrative status, or economic function. Sociologists have long examined how settlement form shapes social life. Gideon Sjoberg’s study of preindustrial cities distinguished them from industrial cities, while Lewis Mumford traced the historical development of the city as a container of culture and power. Louis Wirth identified size, density, and heterogeneity as defining features of urbanism, and Robert Park and the Chicago School treated the city as a social ecology of competing groups and neighborhoods. Walter Christaller’s central place theory explained how settlements form hierarchies according to the services they provide, and Manuel Castells analyzed cities as sites of collective consumption and conflict. Urban settlements also include informal settlements, where residents lack secure tenure or services. Understanding their origins, structure, and inequalities is essential for studying migration, housing, governance, and sustainable development.
