Urban Areqs I the United States are divided into census tracts that contain approximately 5,000 residents and correspond, where possible, to neighboring boundaries,

Combining the three models

The here models taken individually do not explain why different types of people live in distinctive parts of the city. But if the models are combined rather than considered independently, they help geographers explain where different types of people live in the city, such as Dallas, Texas.

Limitations of the models

Critics point out that the models are too simple and fail to consider the variety of reasons that lead people to select particular residential locations. Because the three models are all based on conditions that excited in the u.s. Cities between the two world wars, critics also question their relevance to contemporary urban patterns in the United States or in other countries.
