refers to the location of a place relative to its surroundings and its connectivity to other places

city-state

consists of an urban center/city and its surrounding territory and agricultural villages

urban hearth

areas generally associated with defensible sites and river valleys in which seasonal floods and fertile soils allowed for an agricultural surplus

is usually defined as a central city plus land developed for commercial, industrial, or residential purposes, and includes the surrounding suburbs

city

a higher-density area with territory inside officially recognized political boundaries

metropolitan area

metro area

a collection of adjacent cities economically connected across which population density is high and continuous

metropolitan statistical area

another way to define a city

consists of a city of at least 50,000 people

surrounds places with high social and economic integration, and connection

describes the urban growth based on transportation technology

pedestrian cities

cities shaped by the distances people could walk

streetcar suburbs

communities that grew up along rail lines

often creates a pinwheel shaped city

suburbanization

involves the process of people moving usually from cities to residential areas on the outskirts of cities

sprawl

the rapid expansion of the spatial extent of a city and occurs for numerous reasons such as growth of suburbs or lower land costs compared to inner cities

leapfrog development

where developers purchase land and build communities beyond the periphery of the city’s built area

cities that exert influence far beyond their national boundaries

EX: New York, London, Paris, Tokyo

urban hierarchy

a ranking based on influence or population size

nodal cities

command centers on a regional and occasionally national level

urban system

an interdependent set of cities that interact on the regional, national, and global scale

rank-size rule

describes one way in which the sizes of cities within a region may develop

high-order services

usually expensive

need a large number of people to support

only occasionally utilized

Lower-order services

usually less expensive than higher-order services and require a small population to support

used on daily or weekly basis

primate city

the largest city in an urban system that’s twice as large as the next largest city

more developed that other cities in the area

EX: London and Mexico city

gravity model

the larger and closer places are to each other they will have more interactions than places smaller and farther from each other

central place theory

explains the distribution of cities of different sizes across a region by using consumer behavior to explain the distribution of settlements

central place

a location where people go to receive goods and services

market area

a zone that contains people who will purchase goods or services and surrounds a central place

hexagonal hinterlands

a market area in the shape of a hexagon that allowed for central places of different sizes to distribute themselves in a clean pattern across the region

threshold

the size of population necessary for any particular service to exist and remain profitable

range

the distance people will travel to obtain specific goods or services

functional zones

the idea that portions of an urban area have specific and distinct purposes

central business district (CBD)

the commercial heart of the city

bid-rent theory

explains agricultural land use in central business districts: land in the center of the city will cost more than land farther from the city’s center

commensal relationship

when commercial interests benefit each other

EX: restaurants and clothing stores having safe zones

residential zones

areas where people live

concentric zone model/Burgess model

describes a city as a series of rings that surrounds a CBD

sector model/Hoyt’s model

describes how different types of land use and housing were all located near a CBD early in a city’s history and gre outward

Harris and Ullman multiple-nuclei model

studied changes in cities in the 1940s and suggested that functional zonation occurred around multiple centers/nodes

peripheral model

a variant of the multiple-nuclei model

describes suburban neighborhoods surrounding an inner city and served by nodes of commercial activity along a ring road or beltway

galactic city model

suburban growth results from the increase in built highways and improved transportation in and out of the city

mosque

the center of an Islamic city

usually surrounded by complex structures to serve the public (schools, soup kitchens)

citadel

a fort designed to protect the city

suqs

traditional outdoor markets or covered bazaars

Griffin-ford model

used to describe Latin American cities

puts a 2-part CBD in the center of the city and a traditional market center adjacent to it

commercial spine

a spine/corridor of theaters, parks, restaurants

mall

a growing secondary center that ends a commercial spine

periferico

the outer ring of the city that shows poverty and lack of infrastructure

shantytowns

areas of poorly built housing

favelas/barrios

neighborhoods marked by extreme poverty, homelessness and lawlessness

disamenity zones

areas that are not connected to city services and under the control of criminals

traditional CBD

existed before European colonization and has small shops clustered along the streets

colonial CBD

broad straight avenues and large homes, parks, and administrative centers

informal economy zone

periodic markets

where small-scale markets congregate weekly or yearly to sell their goods

informal settlements/squatter settlements

densely populated settlements often on the outskirts of cities

EX: Kibera

McGee model

describes land use of cities in SE Asia

the focus of the city is often a former colonial port zone

zoning ordinances

Regulations that define how property in specific geographic regions may be used

Urban planning

A process of promoting growth and controlling change in land use

Residential zones

Those areas of a city devoted to where people live rather than to commercial or industrial functions

Inner city

The declining of population and housing unit density as one moves farther from the inner city

Filtering

A process where houses pass from one social group to another

Invasion and succession

The process by which one social or ethnic group gradually replaces another through filtering

Urban Infill

The process of increasing the residential density of an area by replacing open space and vacant, housing with residences

Also reduces urban sprawl on the outer edges of a city

Infrastructure

The facilities and systems that serve the population

Municipal
