Multiple Nuclei Theory

● Developed in the 1945’s

● Harris and Ullman made the argument that the “city's downtown core” was losing its importance in relation to the rest of the city

● A cities structure is made up of more than one node, or center in which the cities people and activities revolve around.

In contrast to the Concentric and Zone Models, both of which involve a single center, this theory argues that multiple centers of urban activity and sociology arise as a result of ethnic, cultural, business, educational, and other influences.

Multiple Nuclei Theory

Example: Consider the greater New Haven area. The center of New Haven is dominated by a large university, while Bridgeport is built around a port, and North Haven is a focus of light industry. Other nuclei exist within the region, centered around shopping, recreation, and ethnic communities.
