Ford-Griffin Model
Cities in Periphery/Semi-Periphery
Experience disproportionate population concentrations in capital
Primate Cities dominate urban systems. Population attracted from rural areas
Squatter districts accommodate immigrants from rural areas - create mirror imaged concentric zone pattern with upper class in central areas and social status declines as distance increases from center.
CBD (Central Business Development) has both traditional and modern elements
High class homes surround CDB, Spine, and Mall
Common to find massive peripheries

Zone of In Situ Accretion
Prime Example: Mexico City, Mexico
"City Life" - culture norm in Latin America. (Primate Cities)
Most jobs downtown commute to CDB
Two parts - modernized CDB and traditional "market" of small, street-oriented business
"Spine" - Continuation of features of city center along a main wide street (upper-middle-class housing) – connecting elite commercial zone
Barrios and Favelas (slums) - outskirts of the city. Transition zone of (in situ accretion) when times are good.
