Quick Reference
Urbanization
The process by which populations shift from rural to urban areas, leading to the growth of cities in both size and density. Urbanization transforms economic activities, social relationships, and cultural practices as agrarian societies become increasingly metropolitan.
Gentrification
The process by which higher-income residents and commercial interests move into lower-income urban neighborhoods, driving up property values, rents, and the cost of living, often displacing long-term residents and altering the cultural character of the area.
Residential Segregation
The physical separation of population groups into distinct neighborhoods based on race, ethnicity, class, or other social characteristics. Segregation can result from discriminatory policies, economic inequality, or voluntary clustering and has profound effects on access to opportunities.
Concentric Zone Model
A model of urban land use developed by Ernest Burgess in the 1920s proposing that cities grow outward from a central business district in a series of concentric rings, each characterized by different land uses, income levels, and social conditions.
Urban Sprawl
The uncontrolled, low-density expansion of urban development into surrounding rural areas, characterized by automobile dependence, strip malls, single-family housing subdivisions, and the separation of residential, commercial, and industrial zones.
Social Disorganization Theory
A theory from the Chicago School arguing that crime and deviance result not from individual pathology but from the breakdown of communal institutions and social bonds in neighborhoods marked by poverty, residential instability, and ethnic heterogeneity.
Right to the City
A concept formulated by Henri Lefebvre asserting that all urban inhabitants, not just property owners, have a fundamental right to participate in shaping the spaces they live in and to access the resources and opportunities the city offers.
Urban Ecology
An approach originating with the Chicago School that applies principles from plant and animal ecology to the study of human communities in cities, analyzing competition, invasion, succession, and symbiosis among social groups occupying urban space.
Global City
A concept developed by Saskia Sassen describing cities that serve as key nodes in the global economy, concentrating financial services, corporate headquarters, and advanced producer services while also exhibiting extreme income polarization between elite professionals and low-wage service workers.
Community Organizing
A collective process through which residents of a neighborhood build power by mobilizing people and resources to address shared concerns such as housing conditions, policing, environmental hazards, or inadequate public services.
