Cidade Tiradentes (district of São Paulo) in the context of "Bedroom communities"

A commuter town is a populated area that is primarily residential rather than commercial or industrial. Routine travel from home to work and back is called commuting, which is where the term comes from. A commuter town may be called by many other terms: "bedroom community" (Canada and northeastern US), "bedroom town", "bedroom suburb" (US), "dormitory town" (UK). The term "exurb" was used from the 1950s, but since 2006, is generally used for areas beyond suburbs and specifically less densely built than the suburbs to which the exurbs' residents commute.
