What does suburbanization mean?
Suburbanization names the demographic and geographical process by which residents, housing, and development move from central cities to suburban areas, especially along the urban fringe. It also describes the resulting spread of low-density residential development beyond city boundaries. The term is common in geography, demography, urban planning, and social history, especially in accounts of postwar growth in North America and other predominantly urban societies. Depending on context, it can carry neutral descriptive force or signal concerns about sprawl, automobile dependence, and weakening of central neighborhoods without saying those outcomes are inevitable. Unlike urbanization, which concentrates activity in cities, suburbanization describes movement outward from them. It is useful because it names both a population movement and the physical reshaping of metropolitan landscapes that follows it.

Where does suburbanization come from?
The word combines the adjective suburban with the suffix -ization and emerged in the 19th century as residential growth increasingly extended beyond urban centers. Suburban itself derives from Latin suburbium, an outlying district or part of a city, formed from sub- meaning 'under' or 'below' and urbs meaning 'city'. This Latin inheritance is reflected in related forms such as suburb, suburban, and suburbia.
