Comprehensive Guide to Urban Geography

Site

The absolute location and physical characteristics of a place, including terrain, soil, climate, and water sources.

Situation

The relative location of a place in relation to surrounding physical and cultural features, determining its connectivity and significance.

Sail-Wagon Epoch

First transportation epoch (1790–1830) with slow, water-based travel and coastal port cities.

Iron Horse Epoch

Second transportation epoch (1830–1870) characterized by the growth of cities along rail lines and the arrival of steamboats.

Steel Rail Epoch

Third transportation epoch (1870–1920) marked by transcontinental railways and industrialization, allowing for skyscrapers.

Auto-Air-Amenity Epoch

Fourth transportation epoch (1920–1970) where car travel led to suburbanization and expanded urban footprints.

High-Technology Epoch

Fifth transportation epoch (1970–Present) characterized by satellite cities and telecommuting.

Megacities

Metropolitan areas with over 10 million people, increasingly common in the Semi-Periphery.

Metacities

Massive urban regions with over 20 million people.

World Cities

Key centers of economic, cultural, and political activity that are globally influential, such as London and New York.

Rank-Size Rule

A rule in developed nations indicating that the n-th largest city is 1/n the size of the largest city.

Primate City Rule

A system where the largest city is disproportionately larger than the second-largest city, indicating uneven development.

Gravity Model

A model predicting interaction likelihood between two places based on population and distance.

Central Place Theory

A theory explaining the distribution of services, visualizing market areas as hexagons to prevent gaps.

Bid-Rent Theory

The economic theory that land costs decrease as one moves away from a city center.

Concentric Zone Model

A model describing urban land use patterns as concentric rings around a central business district.

Sector Model

A model proposing that cities develop in wedges or sectors based on transportation routes.

Multiple Nuclei Model

A model where cities have multiple centers of activity, each attracting specific services.

Galactic City Model

A model representing post-industrial U.S. cities with decentralized business districts and edge cities.

Latin American City Model

A model characterized by a spine of commercial activity and peripheral poverty areas.

Southeast Asian City Model

A model with no formal CBD focusing on colonial port zones and ethnic commercial areas.

Sub-Saharan African City Model

A model with multiple CBDs influenced by colonialism and traditional economic practices.

Suburbanization

The movement from urban areas to the suburbs, accelerated by post-WWII policies.

Urban Sprawl

The uncontrolled expansion of urban areas into the surrounding countryside.

Boomburbs

Rapidly growing suburban cities with populations over 100,000, self-sustaining economically.

Exurbs

Affluent residential areas beyond the suburbs, often for remote workers seeking open space.

Redlining

The practice of refusing loans to residents in certain neighborhoods, contributing to racial segregation.

Blockbusting

A practice where real estate agents induce white residents to sell their homes cheaply to minorities.

Gentrification

The transformation of low-income neighborhoods into middle/upper-class areas, often displacing original residents.

Squatter Settlements

Informal settlements arising from rapid urbanization, often without legal land tenure.

New Urbanism

A planning philosophy promoting walkability, mixed-use development, and connected communities.

Smart Growth

Urban planning principles aimed at limiting sprawl and preserving farmland.

Brownfield

An abandoned industrial site with potential for redevelopment after remediation.

Greyfield

Failing commercial land, like dead malls, often characterized by extensive parking lots.

Quantitative Data

Numerical data used for statistical analysis and planning, such as census data.

Qualitative Data

Narrative or descriptive data aiming to capture the social and emotional attributes of neighborhoods.

Trend vs. Model

The misunderstanding of theoretical models as actual current trends in urban geography.

Megacity vs. World City

A megacity is defined by population size, while a world city is defined by global influence and connectivity.

Primate City Misconception

The incorrect belief that every country has a primate city; some may follow rank-size distribution instead.

Perfect Example of Site

Describing a place's physical characteristics, such as 'the island is muddy'.

Perfect Example of Situation

Describing a place's connectivity, such as 'the island is near a trade route'.

Laws of the Indies

Colonial regulations dictating urban planning in Latin America, emphasizing a grid pattern.
