Urban-Realms Model As a means of improving upon the multiple nuclei model, the geographer James E. Vance, Jr. proposed the urban-realms model in 1964. Using this model, Vance was able to look at San Franciscos urban ecology and summarize economic processes into a sturdy model. What the model suggests is that cities are made up of small realms which are self-sufficient urban areas with independent focal points. The nature of these realms is examined through the lens of five criteria: The topological terrain of the area, including water barriers and mountains. The size of the metropolis as a whole. The amount and strength of the economic activity taking place within each of the realms. The accessibility internally of each realm in regards to its major economic function. The inter-accessibility across the individual suburban realms. This model does a good job at explaining suburban growth and how certain functions that are normally found in the CBD can be moved to the suburbs (such as shopping malls, hospitals, schools, etc.). These functions diminish the importance of the CBD and instead create distant realms that accomplish approximately the same thing.
