Concentric Zone Model By: Milan Haddad and Carlie Wilson Definition The Concentric Zone Model (also known as Burgess Model) is one of the earliest and simplest theoretical models to explain urban social structures. Design This model (which was created in 1925 by an Ernest Burgess) is a series of equidistant circles radiating outward from one central zone, with each circle representing a different social or business zone. It can be observed that quality of living increases as distance away from CBD increases, as housing and transportation costs increase with distance. Zone 6 This zone is the CBD (Central Business District) which is the typically at the center of a city and has a large concentration of business and commerce. This is also usually accompanied by high property values. Zone 5 This is the the Factory Zone. This zone is characterized by a ring of factories and less “high class” businesses surrounding the CBD. Zone 4 This is the Transitional Zone. It is an area where the land use is changing, hence the name. It contains industry and working-class housing. Zone 3 This is the Working-Class Zone. It is also known as the inner-suburbs, but is today known as the inner-city. This zone is mainly residential and is at an advantage because it is located near the major zones of employment while keeping housing costs low. Zone 2 This is the Residential Zone. Here we see housing and transportation cost rising as the location becomes farther and farther away from the CBD. The overall quality of living rises here. Zone 1 This is the Commuter Zone. This zone is mainly occupied by high-class residents in expensive, rural, suburban homes. These residents live this far not only to get away from the lower-class, run-down, inner-city areas, but also because they can afford the expensive daily commutes to the inner city where they are employed..

Concentric Zone Theory
Lecture-04 M.A.(Semester-II) PAPER-8 Urban Sociology CONCENTRIC ZONE THEORY Dr. Shankar Kumar Lal University Department of Sociology Lalit Narayan Mithila University Kameshwarnagar,Darbhanga E-mail: [email protected] Mobile: +91-8252199182 CONCENTRIC ZONE THEORY ORIGIN . Developed in the 1920’s by Ernest Burgess and Robert Park, University of Chicago . Hypothesis of this theory is that cities grow and develop outwardly in concentric zones. Sought to explain the socioeconomic divides in and out of the city . Model was based on Chicago’s city layout . First theory to explain the distribution of social groups CONCENTRIC ZONE THEORY….? • Social structures extend outward from one central business area. • Population density decreases towards outward zones • Shows correlation between socioeconomic status and the distance from the central business district • Also known as the Burgess Model, the Bull’s Eye Model, the Concentric Ring Model, or the Concentric Circles Model. Concentric Zone Model ZONE 1: CENTRAL BUSINESS DISTRICT(CBD) • Non-residential center for business. • “Downtown” area • Emphasis on business and commerce • Commuted to by residents of other zones Commercial centre . First, the inner most ring zone or nucleolus of the city is a commercial centre also called Central Business District (CBD) in North America and western countries. This zone is characterized by high intensity of commercial, social and civic amenities. It is the heart of the city which includes department stores, office buildings, shops, banks, clubs, hotels, theatres and many other civic buildings. Being the centre of commercial activities and location, it is accessible from all directions and attracts a large number of people.

Metropolitan Evolution, Urban Images, and the Concentric Zone Model
METROPOLITAN EVOLUTION, URBAN IMAGES, AND THE CONCENTRIC ZONE MODEL LARRY R. FoRD San Diego State College URBAN ERAS AND THE CITYSCAPE According to Edward Price, "Mention the name of a city and the mind of a listen er who knows it will most likely identify it with a visual image, one of its landscape. The landscape provides an expression of the city's inner workings and its past."1 Cul tural differences, including great differences in technology and landscape tastes, can, of course, make for important variation in the cityscapes of the world, but considerable variations in the urban landscape can also be found in the cities of North America. John Borchert, in his article, "American Metropolitan Evolution," states that "the landscapes of any American city reflect countless decisions and actions from the time of settlement to the present. The results are apparent not only in differences in land use but in the kaleidoscopic variety of building facades, street patterns, and lot sizes. Early actions pre-. eluded or frustrated many other locational decisions. The metropolitan physical plant has accumulated through various historical epochs, and clearly those epochs were dis tinguishable one from the other by different ideas and technologies."2 Borchert, Price and others have seen the city as a stock concept; the physical land scape of one era greatly modifies man's adjustment to space in other eras. This problem of "adjusting to space," however, can be looked at from a cultural or behavioral point of view as well as an economic one. It is the cityscape which provides the clearest images and cognative maps that people have of a city and these images and maps should be incorporated in our urban models along with the existing "economic man" theories.

Three Models of Urban Growth (Land Use)
CHANGING CITIES: Three Models of Urban Growth (Land Use) The study of urban land use generally draws from three different descriptive models. These models were developed to generalize about the patterns of urban land use found in early industrial cities of the U.S. Because the shape and form of American cities changed over time, new models of urban land were developed to describe an urban landscape that was becoming increasingly complex and differentiated. Further, because these are general models devised to understand the overall patterns of land use, none of them can accurately describe patterns of urban land use in all cities. In fact, all of these models have been criticized for being more applicable to cities in the U.S. than to cities of other nations. Other criticisms have focused on the fact that the models are static; they describe patterns of urban land use in a generic city, but do not describe the process by which land use changes. Despite these criticisms, these models continue to be useful generalizations of the way in which land is devoted to different uses within the city. Below, we will examine the Concentric Zone Model, Sector Model and Multiple Nuclei Model of urban land use. Concentric Zone Model: The concentric zone model was among the early descriptions of urban form. Originated by Earnest Burgess in the 1920s, the concentric zone model depicts the use of urban land as a set of concentric rings with each ring devoted to a different land use (see Figure 1). The model was based on Burgess’s observations of Chicago during the early years of the 20th century.

Hoffman 1,2,* , Vivek Shandas 3 and Nicholas Pendleton 1,2 1 Science Museum of Virginia, Richmond, VA 23220, USA; [email protected] 2 Center for Environmental Studies, Virginia Commonwealth University, Richmond, VA 23220, USA 3 Nohad A. Toulan School of Urban Studies and Planning, Portland State University, Portland, OR 97201, USA; [email protected] * Correspondence: jhoff[email protected] Received: 5 November 2019; Accepted: 3 January 2020; Published: 13 January 2020 Abstract: The increasing intensity, duration, and frequency of heat waves due to human-caused climate change puts historically underserved populations in a heightened state of precarity, as studies observe that vulnerable communities—especially those within urban areas in the United States—are disproportionately exposed to extreme heat. Lacking, however, are insights into fundamental questions about the role of historical housing policies in cauterizing current exposure to climate inequities like intra-urban heat. Here, we explore the relationship between “redlining”, or the historical practice of refusing home loans or insurance to whole neighborhoods based on a racially motivated perception of safety for investment, with present-day summertime intra-urban land surface temperature anomalies. Through a spatial analysis of 108 urban areas in the United States, we ask two questions: (1) how do historically redlined neighborhoods relate to current patterns of intra-urban heat? and (2) do these patterns vary by US Census Bureau region? Our results reveal that 94% of studied areas display consistent city-scale patterns of elevated land surface temperatures in formerly redlined areas relative to their non-redlined neighbors by as much as 7 ◦C.

Compare and Contrast the Concentric, Sector and Multiple Nuclei Models
KEY Compare and contrast the Concentric, Sector and Multiple nuclei models The Concentric, Sector models and multiple nuclei models have many features in common: 1) Both models focus on importance of accessibility. The centrally located C.B.D. is the most accessible and its land value or rent-bid is the highest. 2) Distant decay theory is applicable in both models. Land value and population density decline with distance from the central places. 3) There are clear-cut and abrupt boundaries between the land-use zones. 4) Both concern the study of ground-floor functions instead of the three-dimensional study as height of buildings is neglected 5) Residential segregation Social-economic status segregates residential areas. The lower-income groups live in the inner city which is suffering from urban decay or in areas near the factory zone. Nearness to working places reduces time and cost of transport, but gives better working opportunities and easiness of obtaining various order of goods and services. In contrast, the higher- income groups occupy the urban periphery with better living environment far away from the factory zone and the lower-income groups. Their implicit assumptions are: 1) Great variation in characteristics e.g. heterogeneity of the population in culture and society. 2) Competition for centrality because of limited space leading to highest land value. The opposite is true of peripheral areas. 3) City centre being centre of employment. 4) Commercial and industrial base to the economy of the city. 5) Private ownership of property and capitalist mode of competition for space. 6) Expanding area and population of the city by invasion and succession.

Urban Geography Urban Patterns
AP Human Geography Urban Geography Urban Patterns A large city is stimulating and agitating, entertaining and frightening, welcoming and cold. A city has something for everyone, but a lot of those things are for people who are different from you. Urban geography helps to sort out the complexities of familiar and unfamiliar patterns in urban areas Key Issues 1. Where have urban areas grown? 2. Where are people distributed within urban areas? 3. Why do inner cities have distinctive problems? 4. Why do suburbs have distinctive problems? Geographers help explain what makes city and countryside Urban different places. Urban geographers are interested Geographers in the where question at two scales. First, geographers examine the global distribution of urban settlements. Geographers are also interested in where people and activities are distributed within urban spaces. Models have been developed to explain why differences occur within urban areas. The major physical, social, and economic contrasts are between inner-city and suburban areas. We all experience the interplay between globalization and local diversity of urban settlements. Many downtowns have a collection of high-rise buildings, towers, and Urban landmarks that are identifiable even to people who have never visited them. Geographers On the other hand, suburban houses, streets, schools, and shopping centers look very much alike from one American city to another. In more developed regions, people are increasingly likely to live in suburbs. People wish to spread across the landscape to avoid urban problems, but at the same time they want convenient connections to the city’s jobs, shops, culture, and recreation. Geographers describe where different types of people live and try to explain the reasons for the observed patterns.

Multiple-Nuclei Model: AP Human Geography Crash Course
Multiple-Nuclei Model: AP Human Geography Crash Course Are you an urbanite? Whether you like it or not, you are probably one of the growing numbers of people in the United States who live either in a city or close enough to quickly travel to one. Cities are growing much faster than rural areas, and the dynamics of urban geography are an important subject to know about for the AP Human Geography exam. There are several classic models used to understand and explain the internal structures of cities and urban areas, and we are going to learn about Harris and Ullman’s Multiple-Nuclei Model in this AP Human Geography study guide. What is a City? Cities are at the center of every advanced society and act as the hub of economic, social and political activities in that area. They have a variety of shapes and functions, and their geography impacts the daily lives of those who live in the city and surrounding areas. All cities provide their residents a variety of services and functions: shopping, manufacturing, transportation, education, medical, and protective services. Cities evolved over time, and if a city had favorable factors (agriculture, access to water, trade, defense), its population increased. This led to urbanization (rapid growth, and migration to large cities). This increase in urban population resulted in rapid expansion of the city and greater urbanization of the society. After the conclusion of World War II, North America experienced rapid urbanization. There was a need for housing outside of the core urban areas due to growing population and demand.

Theories of Urban Growth
THEORIES OF URBAN GROWTH • Although several theories have been developed to explain the dynamics of city growth, all such theories are based upon the operation of five ecological processes of concentration, centralization, invasion and succession and observations based upon it about actual city growth in concrete situations. • However, one can hardly find a theory of an ideal pattern of urban dynamics as growth of particular city depends upon many factors, the basic one being natural location of a city .Nevertheless, one can notice a set of common principles which govern city growth everywhere • The major theories of internal structure of urban settlements have been advanced on the basis of empirical investigations conducted in the Western urban society, particularly in North America and Europe. • . Concentric zone model • Ernest Burgess is the pioneer and his theory on city dynamics which provides the base for the later theorists on the subject. The hypothesis of this theory is that cities grow and develop outwardly in concentric zones. Burgess set out to evolve a theory of dynamics but he arrived at a theory of patterns of city growth which applies to any stage stages of urban development. According to Burgess, an urban area consists of five concentric zones which represent areas of functional differentiation and expand rapidly from the Justness centre. The zones are: • (1) The loop or commercial centre • (2) The zone of transition. • (3) The zone of working class residence • (4) The residential zone of high class apartment buildings. • (5) The commuter's zone. 1. The loop or central business district or commercial centre: • 1.

Here in this unit you will learn further about the different aspects of cities and their formations. As you already know, urban society is defined as a relatively larger, dense, permanent, heterogeneous settlements whose majority of inhabitants are engaged in non-agricultural occupation. The development of such urban society is very much determined by socio - cultural organisation, climate, topography and economic development. The earliest cities of the world originated near river valleys such as early civilization of lndus (Mohenjodaro, Harrappa), Tigris - Eupharates (Lagas Ur, Uruk), Nile (Memphis, Thebes) 5 7 and Hwang Ho (Chen-Chan An Yang). These early development of urban settlements evolved with changing technology and human needs. Trade and commercial activities and settled agriculture were major facilitators; even today these,factors are very much relevant in the growth of a city.
