suburb

n. residential area lying on the outskirts of a city or town

Suburbs are commonly defined as residential areas on the outskirts of a city or large town. Most modern suburbs are commuter towns with many single-family homes. Many suburbs have some degree of political autonomy and most have lower population density than inner city neighborhoods. Mechanical transport, including automobiles, enabled the 20th century growth of suburbs, which tend to proliferate near cities with an abundance of adjacent flat land.
