An "Edge City" is a term used to describe a new urban development that emerges on the outskirts of a traditional city. These areas typically feature a mix of residential, commercial, and recreational spaces, often designed to accommodate the needs of suburban populations. Edge cities usually arise due to suburban sprawl and the increasing demand for office space, shopping centers, and entertainment options outside the urban core. The concept of Edge City was popularized by urban planner Joel Garreau in his 1991 book, where he identified key characteristics such as high employment levels, diverse amenities, and a lack of historical significance. These developments often serve as economic hubs, attracting businesses and residents alike, while also raising questions about urban planning and sustainability.
