Answer to Question 2
Functionalists, in studying the growth of cities, emphasize the life cycle of urban
growth. Burgess developed the concentric zone modela description of the process of
urban growth that views the city as a series of circular areas or zones, each
characterized by a different type of land use that developed from a central core. Two
important ecological processes are involved: (1) Invasionthe process by which a new
category of people or type of land use arrives in an area previously occupied by
another group or type of land use. (2) Successionthe process by which a new
category of people or type of land use gradually predominates in an area formerly
dominated by another group or activity. Invasion and succession theoretically operate in
an outward movement, except when gentrification occurs. Gentrification is the process
by which members of the middle and upper-middle classes, especially whites, move
into the central-city area and renovate existing properties. The concentric zone model
demonstrates how economic and political forces play an important part in the location
of groups and activities, and it shows how a large urban area can have internal
differentiation.
