An "Edge City" is a term used to describe a suburban area that has developed into a significant economic center, often located on the outskirts of a major city. These areas typically feature a mix of office spaces, retail shops, and entertainment options, making them self-sufficient and attractive for residents and businesses alike. Edge cities often emerge as a result of urban sprawl, where people move away from traditional city centers in search of more affordable housing and better quality of life. Examples of edge cities include Tysons Corner in Virginia and Irvine in California, which have transformed from rural or undeveloped land into bustling urban hubs.
