The process describes the growth of areas on the fringes of major cities. This involves a population shift from central urban areas into the outer edges, resulting in the expansion of residential, commercial, and industrial developments in previously rural or less developed regions. An example of this is the expansion of residential communities surrounding a major metropolitan area, coupled with the development of associated infrastructure such as roads, schools, and shopping centers to support the growing population.
This phenomenon holds significant importance in understanding population distribution, land use patterns, and economic development. It impacts transportation systems, environmental sustainability, and social dynamics. Historically, it has been driven by factors such as increased affordability of housing outside city centers, improved transportation infrastructure (like the automobile and highways), and a desire for larger living spaces and perceived safety. This process has reshaped the landscape of many countries, especially in the developed world, influencing everything from political landscapes to cultural trends.
