Satellite city

A satellite city or satellite town is a smaller municipality or settlement that is part of (or on the edge of) a larger metropolitan area and serves as a regional population and employment center. It differs from mere suburbs, subdivisions and especially bedroom communities in that it has employment bases sufficient to support its residential population, and conceptually, could be a self-sufficient community outside of its larger metropolitan area. However, it functions as part of a metropolis and experiences high levels of cross-commuting (that is, residents commuting out of and employees commuting into the city).
