A dormitory town is a term used to describe a residential area that lacks its own economic activity and is populated primarily by people who commute to work in other areas. Alternatives to the term "dormitory town" include "bedroom community," "suburbia," "commuter town," "residential suburb" and "residential community." These terms are often used interchangeably, but each has its own nuances. For example, "suburbia" may connote middle-class affluence, while "commuter town" calls to mind a central transportation hub. Regardless of the terminology used, dormitory towns are a ubiquitous part of modern life as people continue to migrate from urban cores to quieter, more residential areas outside of cities.
