A commuter town is an urban community that is primarily residential, from which most of the workforce commutes out to earn their livelihood. Many commuter towns act as suburbs of a nearby metropolis that workers travel to daily, and many suburbs are commuter towns. Commuter towns belong to the metropolitan area of a city, and a ring of commuter towns around an urban area is known as a commuter belt.
A commuter town may also be known as a bedroom community or "bedroom suburb" (Canada and U.S. usage), a dormitory town (UK Commonwealth and Ireland usage), or less commonly a dormitory village (UK Commonwealth and Ireland). These terms suggest that residents sleep in these neighborhoods, but mostly work elsewhere; they further suggest that these communities have little commercial or industrial activity beyond a small amount of retail, oriented toward serving the residents.
