The Urban Structure Models

The models' information combined explains where different types of people live in a city. The sector theory says that a higher income family won't live in the same neighborhood as a low-income family. The concentric zone model says the owner-occupant will live in the outer ring and the renter in the inner ring. The multiple nuclei theory says that people are likely to live around people with the same ethnicity as them.
