CHAPTER II

THE GROWTH OF THE CITY: AN INTRODUCTION TO A RESEARCH PROJECT

The outstanding fact of modern society is the growth of great cities.

Nowhere else have the enormous changes which the machine industry has

made in our social life registered themselves with such obviousness as

in the cities. In the United States the transition from a rural to an

urban civilization, though beginning later than in Europe, has taken

place, if not more rapidly and completely, at any rate more logically in

its most characteristic forms.

All the manifestations of modern life which are peculiarly urban—the

skyscraper, the subway, the department store, the daily newspaper, and

social work—are characteristically American. The more subtle changes in

our social life, which in their cruder manifestations are termed “social

problems,” problems that alarm and bewilder us, as divorce, delinquency,

and social unrest, are to be found in their most acute forms in our

largest American cities. The profound and “subversive” forces which have

wrought these changes are measured in the physical growth and expansion

of cities. That is the significance of the comparative statistics of

Weber, Bücher, and other students.

These statistical studies, although dealing mainly with the effects of

urban growth, brought out into clear relief certain distinctive

characteristics of urban as compared with rural populations. The larger

proportion of women to men in the cities than in the open country, the

greater percentage of youth and middle-aged, the higher ratio of the

foreign-born, the increased heterogeneity of occupation increase with

the growth of the city and profoundly alter its social structure. These

variations in the composition of population are indicative of all the

changes going on in the social organization of the community. In fact,

these changes are a part of the growth of the city and suggest the

nature of the processes of growth.

The only aspect of growth adequately described by Bücher and Weber was

the rather obvious process of the _aggregation_ of urban population.

Almost as overt a process, that of _expansion_, has been investigated

from a different and very practical point of view by groups interested

in city planning, zoning, and regional surveys. Even more significant

than the increasing density of urban population is its correlative

tendency to overflow, and so to extend over wider areas, and to

incorporate these areas into a larger communal life. This paper,

therefore, will treat first of the expansion of the city, and then of

the less-known processes of urban metabolism and mobility which are

closely related to expansion.

EXPANSION AS PHYSICAL GROWTH

The expansion of the city from the standpoint of the city plan, zoning,

and regional surveys is thought of almost wholly in terms of its

physical growth. Traction studies have dealt with the development of

transportation in its relation to the distribution of population

throughout the city. The surveys made by the Bell Telephone Company and

other public utilities have attempted to forecast the direction and the

rate of growth of the city in order to anticipate the future demands for

the extension of their services. In the city plan the location of parks

and boulevards, the widening of traffic streets, the provision for a

civic center, are all in the interest of the future control of the

physical development of the city.

This expansion in area of our largest cities is now being brought

forcibly to our attention by the Plan for the Study of New York and Its

Environs, and by the formation of the Chicago Regional Planning

Association, which extends the metropolitan district of the city to a

radius of 50 miles, embracing 4,000 square miles of territory. Both are

attempting to measure expansion in order to deal with the changes that

accompany city growth. In England, where more than one-half of the

inhabitants live in cities having a population of 100,000 and over, the

lively appreciation of the bearing of urban expansion on social

organization is thus expressed by C. B. Fawcett:

One of the most important and striking developments in the growth of

the urban populations of the more advanced peoples of the world during

the last few decades has been the appearance of a number of vast urban

aggregates, or conurbations, far larger and more numerous than the

great cities of any preceding age. These have usually been formed by

the simultaneous expansion of a number of neighboring towns, which

have grown out toward each other until they have reached a practical

coalescence in one continuous urban area. Each such conurbation still

has within it many nuclei of denser town growth, most of which

represent the central areas of the various towns from which it has

grown, and these nuclear patches are connected by the less densely

urbanized areas which began as suburbs of these towns. The latter are

still usually rather less continuously occupied by buildings, and

often have many open spaces.

These great aggregates of town dwellers are a new feature in the

distribution of man over the earth. At the present day there are from

thirty to forty of them, each containing more than a million people,

whereas only a hundred years ago there were, outside the great centers

of population on the waterways of China, not more than two or three.

Such aggregations of people are phenomena of great geographical and

social importance; they give rise to new problems in the organization

of the life and well-being of their inhabitants and in their varied

activities. Few of them have yet developed a social consciousness at

all proportionate to their magnitude, or fully realized themselves as

definite groupings of people with many common interests, emotions and

thoughts.[19]

In Europe and America the tendency of the great city to expand has been

recognized in the term “the metropolitan area of the city,” which far

overruns its political limits, and in the case of New York and Chicago,

even state lines. The metropolitan area may be taken to include urban

territory that is physically contiguous, but it is coming to be defined

by that facility of transportation that enables a business man to live

in a suburb of Chicago and to work in the loop, and his wife to shop at

Marshall Field’s and attend grand opera in the Auditorium.

EXPANSION AS A PROCESS

No study of expansion as a process has yet been made, although the

materials for such a study and intimations of different aspects of the

process are contained in city planning, zoning, and regional surveys.

The typical processes of the expansion of the city can best be

illustrated, perhaps, by a series of concentric circles, which may be

numbered to designate both the successive zones of urban extension and

the types of areas differentiated in the process of expansion.

This chart represents an ideal construction of the tendencies of any

town or city to expand radially from its central business district—on

the map “The Loop” (I). Encircling the downtown area there is normally

an area in transition, which is being invaded by business and light

manufacture (II). A third area (III) is inhabited by the workers in

industries who have escaped from the area of deterioration (II) but who

desire to live within easy access of their work. Beyond this zone is the

“residential area” (IV) of high-class apartment buildings or of

exclusive “restricted” districts of single family dwellings. Still

farther, out beyond the city limits, is the commuters’ zone (V)—suburban

areas, or satellite cities—within a thirty- to sixty-minute ride of the

central business district.

This chart brings out clearly the main fact of expansion, namely, the

tendency of each inner zone to extend its area by the invasion of the

next outer zone. This aspect of expansion may be called _succession_, a

process which has been studied in detail in plant ecology. If this chart

is applied to Chicago, all four of these zones were in its early history

included in the circumference of the inner zone, the present business

district. The present boundaries of the area of deterioration were not

many years ago those of the zone now inhabited by independent

wage-earners, and within the memories of thousands of Chicagoans

contained the residences of the “best families.” It hardly needs to be

added that neither Chicago nor any other city fits perfectly into this

ideal scheme. Complications are introduced by the lake front, the

Chicago River, railroad lines, historical factors in the location of

industry, the relative degree of the resistance of communities to

invasion, etc.

The GROWTH OF THE CITY

]

Besides extension and succession, the general process of expansion in

urban growth involves the antagonistic and yet complementary processes

of concentration and decentralization. In all cities there is the

natural tendency for local and outside transportation to converge in the

central business district. In the downtown section of every large city

we expect to find the department stores, the skyscraper office

buildings, the railroad stations, the great hotels, the theaters, the

art museum, and the city hall. Quite naturally, almost inevitably, the

economic, cultural, and political life centers here. The relation of

centralization to the other processes of city life may be roughly gauged

by the fact that over half a million people daily enter and leave

Chicago’s “loop.” More recently sub-business centers have grown up in

outlying zones. These “satellite loops” do not, it seems, represent the

“hoped for” revival of the neighborhood, but rather a telescoping of

several local communities into a larger economic unity. The Chicago of

yesterday, an agglomeration of country towns and immigrant colonies, is

undergoing a process of reorganization into a centralized decentralized

system of local communities coalescing into sub-business areas visibly

or invisibly dominated by the central business district. The actual

processes of what may be called centralized decentralization are now

being studied in the development of the chain store, which is only one

illustration of the change in the basis of the urban organization.[20]

Expansion, as we have seen, deals with the physical growth of the city,

and with the extension of the technical services that have made city

life not only livable, but comfortable, even luxurious. Certain of these

basic necessities of urban life are possible only through a tremendous

development of communal existence. Three millions of people in Chicago

are dependent upon one unified water system, one giant gas company, and

one huge electric light plant. Yet, like most of the other aspects of

our communal urban life, this economic co-operation is an example of

co-operation without a shred of what the “spirit of co-operation” is

commonly thought to signify. The great public utilities are a part of

the mechanization of life in great cities, and have little or no other

meaning for social organization.

Yet the processes of expansion, and especially the rate of expansion,

may be studied not only in the physical growth and business development,

but also in the consequent changes in the social organization and in

personality types. How far is the growth of the city, in its physical

and technical aspects, matched by a natural but adequate readjustment in

the social organization? What, for a city, is a normal rate of

expansion, a rate of expansion with which controlled changes in the

social organization might successfully keep pace?

SOCIAL ORGANIZATION AND DISORGANIZATION AS PROCESSES OF METABOLISM

These questions may best be answered, perhaps, by thinking of urban

growth as a resultant of organization and disorganization analogous to

the anabolic and katabolic processes of metabolism in the body. In what

way are individuals incorporated into the life of a city? By what

process does a person become an organic part of his society? The natural

process of acquiring culture is by birth. A person is born into a family

already adjusted to a social environment—in this case the modern city.

The natural rate of increase of population most favorable for

assimilation may then be taken as the excess of the birth-rate over the

death-rate, but is this the normal rate of city growth? Certainly,

modern cities have increased and are increasing in population at a far

higher rate. However, the natural rate of growth may be used to measure

the disturbances of metabolism caused by any excessive increase, as

those which followed the great influx of southern Negroes into northern

cities since the war. In a similar way all cities show deviations in

composition by age and sex from a standard population such as that of

Sweden, unaffected in recent years by any great emigration or

immigration. Here again, marked variations, as any great excess of males

over females, or of females over males, or in the proportion of

children, or of grown men or women, are symptomatic of abnormalities in

social metabolism.

Normally the processes of disorganization and organization may be

thought of as in reciprocal relationship to each other, and as

co-operating in a moving equilibrium of social order toward an end

vaguely or definitely regarded as progressive. So far as disorganization

points to reorganization and makes for more efficient adjustment,

disorganization must be conceived not as pathological, but as normal.

Disorganization as preliminary to reorganization of attitudes and

conduct is almost invariably the lot of the newcomer to the city, and

the discarding of the habitual, and often of what has been to him the

moral, is not infrequently accompanied by sharp mental conflict and

sense of personal loss. Oftener, perhaps, the change gives sooner or

later a feeling of emancipation and an urge toward new goals.

[Illustration:

CHART II

URBAN AREAS

]

In the expansion of the city a process of distribution takes place which

sifts and sorts and relocates individuals and groups by residence and

occupation. The resulting differentiation of the cosmopolitan American

city into areas is typically all from one pattern, with only interesting

minor modifications. Within the central business district or on an

adjoining street is the “main stem” of “hobohemia,” the teeming Rialto

of the homeless migratory man of the Middle West.[21] In the zone of

deterioration encircling the central business section are always to be

found the so-called “slums” and “bad lands,” with their submerged

regions of poverty, degradation, and disease, and their underworlds of

crime and vice. Within a deteriorating area are rooming-house districts,

the purgatory of “lost souls.” Near by is the Latin Quarter, where

creative and rebellious spirits resort. The slums are also crowded to

overflowing with immigrant colonies—the Ghetto, Little Sicily,

Greektown, Chinatown—fascinatingly combining old world heritages and

American adaptations. Wedging out from here is the Black Belt, with its

free and disorderly life. The area of deterioration, while essentially

one of decay, of stationary or declining population, is also one of

regeneration, as witness the mission, the settlement, the artists’

colony, radical centers—all obsessed with the vision of a new and better

world.

The next zone is also inhabited predominatingly by factory and shop

workers, but skilled and thrifty. This is an area of second immigrant

settlement, generally of the second generation. It is the region of

escape from the slum, the _Deutschland_ of the aspiring Ghetto family.

For _Deutschland_ (literally “Germany”) is the name given, half in envy,

half in derision, to that region beyond the Ghetto where successful

neighbors appear to be imitating German Jewish standards of living. But

the inhabitant of this area in turn looks to the “Promised Land” beyond,

to its residential hotels, its apartment-house region, its “satellite

loops,” and its “bright light” areas.

This differentiation into natural economic and cultural groupings gives

form and character to the city. For segregation offers the group, and

thereby the individuals who compose the group, a place and a rôle in the

total organization of city life. Segregation limits development in

certain directions, but releases it in others. These areas tend to

accentuate certain traits, to attract and develop their kind of

individuals, and so to become further differentiated.

The division of labor in the city likewise illustrates disorganization,

reorganization, and increasing differentiation. The immigrant from rural

communities in Europe and America seldom brings with him economic skill

of any great value in our industrial, commercial, or professional life.

Yet interesting occupational selection has taken place by nationality,

explainable more by racial temperament or circumstance than by old-world

economic background, as Irish policemen, Greek ice-cream parlors,

Chinese laundries, Negro porters, Belgian janitors, etc.

The facts that in Chicago one million (996,589) individuals gainfully

employed reported 509 occupations, and that over 1,000 men and women in

_Who’s Who_ gave 116 different vocations, give some notion of how in the

city the minute differentiation of occupation “analyzes and sifts the

population, separating and classifying the diverse elements.”[22] These

figures also afford some intimation of the complexity and complication

of the modern industrial mechanism and the intricate segregation and

isolation of divergent economic groups. Interrelated with this economic

division of labor is a corresponding division into social classes and

into cultural and recreational groups. From this multiplicity of groups,

with their different patterns of life, the person finds his congenial

social world and—what is not feasible in the narrow confines of a

village—may move and live in widely separated, and perchance

conflicting, worlds. Personal disorganization may be but the failure to

harmonize the canons of conduct of two divergent groups.

If the phenomena of expansion and metabolism indicate that a moderate

degree of disorganization may and does facilitate social organization,

they indicate as well that rapid urban expansion is accompanied by

excessive increases in disease, crime, disorder, vice, insanity, and

suicide, rough indexes of social disorganization. But what are the

indexes of the causes, rather than of the effects, of the disordered

social metabolism of the city? The excess of the actual over the natural

increase of population has already been suggested as a criterion. The

significance of this increase consists in the immigration into a

metropolitan city like New York and Chicago of tens of thousands of

persons annually. Their invasion of the city has the effect of a tidal

wave inundating first the immigrant colonies, the ports of first entry,

dislodging thousands of inhabitants who overflow into the next zone, and

so on and on until the momentum of the wave has spent its force on the

last urban zone. The whole effect is to speed up expansion, to speed up

industry, to speed up the “junking” process in the area of deterioration

(II). These internal movements of the population become the more

significant for study. What movement is going on in the city, and how

may this movement be measured? It is easier, of course, to classify

movement within the city than to measure it. There is the movement from

residence to residence, change of occupation, labor turnover, movement

to and from work, movement for recreation and adventure. This leads to

the question: What is the significant aspect of movement for the study

of the changes in city life? The answer to this question leads directly

to the important distinction between movement and mobility.

MOBILITY AS THE PULSE OF THE COMMUNITY

Movement, per se, is not an evidence of change or of growth. In fact,

movement may be a fixed and unchanging order of motion, designed to

control a constant situation, as in routine movement. Movement that is

significant for growth implies a change of movement in response to a new

stimulus or situation. Change of movement of this type is called

_mobility_. Movement of the nature of routine finds its typical

expression in work. Change of movement, or mobility, is

characteristically expressed in adventure. The great city, with its

“bright lights,” its emporiums of novelties and bargains, its palaces of

amusement, its underworld of vice and crime, its risks of life and

property from accident, robbery, and homicide, has become the region of

the most intense degree of adventure and danger, excitement and thrill.

Mobility, it is evident, involves change, new experience, stimulation.

Stimulation induces a response of the person to those objects in his

environment which afford expression for his wishes. For the person, as

for the physical organism, stimulation is essential to growth. Response

to stimulation is wholesome so long as it is a correlated _integral_

reaction of the entire personality. When the reaction is _segmental_,

that is, detached from, and uncontrolled by, the organization of

personality, it tends to become disorganizing or pathological. That is

why stimulation for the sake of stimulation, as in the restless pursuit

of pleasure, partakes of the nature of vice.

The mobility of city life, with its increase in the number and intensity

of stimulations, tends inevitably to confuse and to demoralize the

person. For an essential element in the mores and in personal morality

is consistency, consistency of the type that is natural in the social

control of the primary group. Where mobility is the greatest, and where

in consequence primary controls break down completely, as in the zone of

deterioration in the modern city, there develop areas of demoralization,

of promiscuity, and of vice.

In our studies of the city it is found that areas of mobility are also

the regions in which are found juvenile delinquency, boys’ gangs, crime,

poverty, wife desertion, divorce, abandoned infants, vice.

These concrete situations show why mobility is perhaps the best index of

the state of metabolism of the city. Mobility may be thought of in more

than a fanciful sense, as the “pulse of the community.” Like the pulse

of the human body, it is a process which reflects and is indicative of

all the changes that are taking place in the community, and which is

susceptible of analysis into elements which may be stated numerically.

The elements entering into mobility may be classified under two main

heads: (1) the state of mutability of the person, and (2) the number and

kind of contacts or stimulations in his environment. The mutability of

city populations varies with sex and age composition, the degree of

detachment of the person from the family and from other groups. All

these factors may be expressed numerically. The new stimulations to

which a population responds can be measured in terms of change of

movement or of increasing contacts. Statistics on the movement of urban

population may only measure routine, but an increase at a higher ratio

than the increase of population measures mobility. In 1860 the horse-car

lines of New York City carried about 50,000,000 passengers; in 1890 the

trolley-cars (and a few surviving horse-cars) transported about

500,000,000; in 1921, the elevated, subway, surface, and electric and

steam suburban lines carried a total of more than 2,500,000,000

passengers.[23] In Chicago the total annual rides per capita on the

surface and elevated lines were 164 in 1890; 215 in 1900; 320 in 1910;

and 338 in 1921. In addition, the rides per capita on steam and electric

suburban lines almost doubled between 1916 (23) and 1921 (41), and the

increasing use of the automobile must not be overlooked.[24] For

example, the number of automobiles in Illinois increased from 131,140 in

1915 to 833,920 in 1923.[25]

Mobility may be measured not only by these changes of movement, but also

by increase of contacts. While the increase of population of Chicago in

1912–22 was less than 25 per cent (23.6 per cent), the increase of

letters delivered to Chicagoans was double that (49.6 per cent)—(from

693,084,196 to 1,038,007,854).[26] In 1912 New York had 8.8 telephones;

in 1922, 16.9 per 100 inhabitants. Boston had, in 1912, 10.1 telephones;

ten years later, 19.5 telephones per 100 inhabitants. In the same decade

the figures for Chicago increased from 12.3 to 21.6 per 100

population.[27] But increase of the use of the telephone is probably

more significant than increase in the number of telephones. The number

of telephone calls in Chicago increased from 606,131,928 in 1914 to

944,010,586 in 1922,[28] an increase of 55.7 per cent, while the

population increased only 13.4 per cent.

Land values, since they reflect movement, afford one of the most

sensitive indexes of mobility. The highest land values in Chicago are at

the point of greatest mobility in the city, at the corner of State and

Madison streets, in the Loop. A traffic count showed that at the rush

period 31,000 people an hour, or 210,000 men and women in sixteen and

one-half hours, passed the southwest corner. For over ten years land

values in the Loop have been stationary, but in the same time they have

doubled, quadrupled, and even sextupled in the strategic corners of the

“satellite loops,”[29] an accurate index of the changes which have

occurred. Our investigations so far seem to indicate that variations in

land values, especially where correlated with differences in rents,

offer perhaps the best single measure of mobility, and so of all the

changes taking place in the expansion and growth of the city.

In general outline, I have attempted to present the point of view and

methods of investigation which the department of sociology is employing

in its studies in the growth of the city, namely, to describe urban

expansion in terms of extension, succession, and concentration; to

determine how expansion disturbs metabolism when disorganization is in

excess of organization; and, finally, to define mobility and to propose

it as a measure both of expansion and metabolism, susceptible to precise

quantitative formulation, so that it may be regarded almost literally as

the pulse of the community. In a way, this statement might serve as an

introduction to any one of five or six research projects under way in

the department.[30] The project, however, in which I am directly engaged

is an attempt to apply these methods of investigation to a cross-section

of the city—to put this area, as it were, under the microscope, and so

to study in more detail and with greater control and precision the

processes which have been described here in the large. For this purpose

the West Side Jewish community has been selected. This community

includes the so-called “Ghetto,” or area of first settlement, and

Lawndale, the so-called “Deutschland,” or area of second settlement.

This area has certain obvious advantages for this study, from the

standpoint of expansion, metabolism, and mobility. It exemplifies the

tendency to expansion radially from the business center of the city. It

is now relatively a homogeneous cultural group. Lawndale is itself an

area in flux, with the tide of migrants still flowing in from the Ghetto

and a constant egress to more desirable regions of the residential zone.

In this area, too, it is also possible to study how the expected outcome

of this high rate of mobility in social and personal disorganization is

counteracted in large measure by the efficient communal organization of

the Jewish community.
