Multiple nuclei model
In demography, an ecological model put forth by Chauncy D. Harris and Edward L. Ullman in the 1945 article "The Nature of Cities." While a city may have started with a central business district, similiar industries with common land-use and financial requirements are established near each other. These groupings influence their immediate neighborhood. Hotels and restaurants spring up around airports, for example. The number and kinds of nuclei mark a city's growth.
