Step 1: The Concentric Zone model, developed by sociologist Ernest Burgess in 1920, describes the distribution of different types of urban areas in concentric rings around the central business district (CBD).
Step 2: The Zone of Transition is the area located adjacent to the CBD. This zone is characterized by mixed residential and commercial uses, along with deteriorating housing. It is often a zone of social and economic change.
Step 3: The other zones in the model, such as the Zone of Independent Working Class, are typically further away from the CBD and have more stable residential areas. The Zone of High-Class Homes is located at the outskirts of the city and is less likely to have mixed uses.
Conclusion: The "Zone of Transition" is the area characterized by mixed residential and commercial establishments in the Burgess model.
