Legal definition of City
The term city defines an urban settlement that has been legally incorporated into an independent governing unit.
With the rapid growth of urban settlements, many urban residents live in suburbs, beyond the boundaries of the central city. Approximately 70% of Americans live in the urbanized areas, including about 30% in central cities and 40% in surrounding jurisdictions.
