CHAPTER I
THE PROBLEM AND DEFINITION OF TERMS USED
During th e past three decades there has been an
Î
increasing interest in population— its numbers, its make-up|
or composition, its distribution in space, and the changes j
I
therein, and its growth* This interest in population is |
not misplaced as the population facts and changes are most
intimately bound up with the immediate welfare of
individuals, and from a broader standpoint with the masses, j
Also, reliable information must be on hand because it is I
essential to effective administration and appraisal of many j
activities of government. Varied information on population|
I
growth and its geographic distribution is also needed by
the business community, and by civic and welfare organiza-
itions. All these must base their future activities, in
jsome part, on projections of future population, and its
distribution. A considered appraisal of underlying
relationships and trends, based upon careful evaluation of
past and present, is basic to projection of the future.
I. THE PROBLEM
Statement of the problem. The purpose of this paper
is to determine whether a mathematical relationship exists
between population density growth and/or growth in Los
2
Angeles County over the years and distance from the Central
Business District.
Importance of the study. Many of the major deci
sions made by government, business men, and others, depend
upon express or implied forecasts of population and its
distribution.
Governmental projections are related to provision
of utilities, schools, highways, etc. From the viewpoint
of business, projections are basic to estimating needs for
office buildings, retail stores, restaurants, and other
services. Community service organizations, too, depend
on projections for estimating future needs for their
activities.
II. DEFINITIONS OF TIR^ USED
Quadrant. As pertains to this thesis the word
''quadrant** refers to the different quarters into which
North-South and East-West rectangular coordinates divide a
circle, drawn with the Central Business District as center.
The four quadrants are numbered in a counter-clockwise
direction. The North-East quadrant is referred to as
Quadrant I, the North-West then being number II, South-West
III, and South-East IV.
Census tract. A census tract is a small geographic
3
area9 as defined by the United States Gensas Bnrean, which
has fairly homogeneous characteristics, and usually
contains a population of between 2,000 and 6,000.
Statistieal area. “ Ehis phrase refers to the Los
Angeles Gonnty Regional Planning Gommission term, with
boundaries defined by the Commission. It is the area ob
tained by the grouping of census tracts into a larger and,
for some statistical purpose, more convenient aggregate.
Method of least squares. The method of least
squares is the method by which a straight line is fitted to
a group of points so as to minimize the sum of the squares
of the deviations from the fitted line.
Slope of line. Slope refers to the ratio of the
rise or fall of a line (generally representing here
logarithm of population) to the corresponding change in
horizontal position (generally representing here distance
from the Central Business District).
Arithmetic paper. Arithmetic paper refers to graph
paper with equal distance between coordinate line rulings.
It is used to show absolute changes in magnitudes.
Semi-logarithmic paper. The term semi-logarithmic
paper refers to graph paper which has an arithmetic scale
on the horizontal axis, and logarithmic scale on the
k
vertical. Semi-logarithmic paper makes it possible to
compare percentage change rather than amonnt of change.
Central Business District. This phrase refers to
the Central Business District of Dos Angeles City. It is
used as the point of origin from which distance analyzed
in this thesis are measured more specifically. Distance
is measured in this thesis from Sixth and Main Street.
III. ORQrMlZkTlGM OF REMAINDER OF TE^ THESIS
This report is organized into four major divisions.
The first covers the purpose, importance of the study, and
a review of the literature.
The second division. Chapters III and IV, delineates
the boundaries of the areas used in analyzing data, and
presents the data used in the analysis, namely Dnited
States Census population figures by census tracts for Los
Angeles County for April 1, 1950, and quarterly estimates
of population for a period of time as published by the
Los Angeles County Regional Planning Gommission.
The third division presents a series of graphs on
growth and growth rates in Los Angeles County, for the
period 1946 to 1956.
The fourth division of this report contains the
summary and conclusions, an appendix, and the bibliography.

REVIEW OF THE LITERATURE
I. TEE EXPANSION OF CALIFORNIA
Although the first Federal Census in California was
taken in 1850, the population estimate for three out of the
twenty-seven ©©unties never reached Washington*^ The
population of the twenty-four counties, for which data did
reach Washington, was 92,597* The total population of all
twenty-seven counties in California is believed to have
been between 140,000 and 165*000. Population reached
From 1860 to 1900, the population increased at a
decennial rate of from 35 to 55 per cent, from 379,994 to
1,485,053* This increase was very rapid, but in line with
the fast expansion of other frontiers, and not at all out
of the ordinary.^
By 1950, the population of California had reached
10,586,233*^ In the period 1950 to 1955, population is

estimated to have increased another 22 per cent, and by
1970 or 1975 California is likely to have overtaken even
New York in population. It will then be the largest state
in the Union with nearly twenty-six million people.4
II. MS EXPANSION OP TEi LOS ANGELES METROPOLITAN AREA
In 1900, the population of the Los Angeles Metro
politan Area, which consists of Los Angeles and Orange
Counties, approximated 190,000. Population increased
rapidly until, in 1940, it reached almost three million

Planning Gommission, Los Angeles County, 1954), p. 22.
In the next decade, from 194© to 1950, the
population went to almost four and one-half million, a
growth of approximately 5© per cent.^
Los Angeles County, in 1940, had the second largest
population of all counties in the United States ; it is
possibly the largest single county now, and has a greater
population than thirty-nine of the forty-eight states.7

If growth Gomtînmes at the present expected rate
the Metropolitan Area will have eight millions of people
by 1970, and it will have become the second largest
metropolitan area in the Waited States*^
, III. POPWLATIOH FOEEGASTIMa
Population forecasting has been going on for many
years in American life. Benjamin Franklin and President
Lincoln both tried their hand in the art of estimating
population growth.9
Boring the last thirty years a number of population
forecasts have been made, but even those once considered
to be **high** forecasts have turned out to be low.l®
Population change, whether it be growth or decline,
result from three items; births, death, and net migration
or emigration.Many studies have been made relating
to each of these factors, and as more is learned of what
affects each, the better should become the resulting

forecasts of population*
Those who try to predict long range growth have, at
best, a tough road to follow; those forecasting only a
short time into the future have the easier job and sire
likely to be more nearly accurate in their predictions.
This paper does not attempt to forecast the growth
of population as a whole* Rather it is an analysis of
L
the distribution of the population surrounding a Central
Business District in an attempt to learn whether population
density and growth can be mathematically related to dis- |
!
tance from this focal point* Certain restricting factors, |
of course, will affect the possible relationship of density
growth to distance from the Central Business District*
These factors include topography, factory sites, freeways,
etc* They have not been studied. This paper only strives
to attain another one of many links in the understanding
of population distribution and growth, and should be so
considered*
IT* URBANIZATION
Since 1900,the flow of population into the
suburbs of metropolitan cities has increased at a higher
12(jertrude Deutsch, **The Trek is to the Suburbs,”
The Conference Board Business Records, 8:378-79* October,
I9Tl:
rate than iias the flow imto the central city* The trek to
the snhnrhs has affected the whole economic stractare of
the metropolitan area; marketing, transportation, manicIpal
financing, etc. This differential in growth rate has
provoked a great deal of discassion. At times, pleumers
and social scientists have arrived at directly opposite
conclasions, and have made conflicting recommendations.
In the period 1910 to 195©, the Wnited States
sahorbs increased by 210 per cent in popalation, while the
nation as a whole only grew by 64 per cent. Estimated
increases from 1950 to 1957 are: United States, 11 per
cent; sabarbia, 18 per cent. It is estimated that daring
the last six years the saborbs have grown six times as fast
as the corresponding cities, and that 80 per cent of fatore
or ban growth will be in the sabarbs.^^
In the period 1950 to 1957, the popalation of Los
Angeles saborbs increased two and one-fourth times as fast
as that of the central area. This figure is a little lower
than for other west coast metropolitan centersthat for

San FrancisCO-Oakland being 4*3; Seattle, 3.6; Portland,
3.2; and San Diego, 2.5. The saborbs of the larger cities
of the United States are expected to continae to grow
rapidly. In no ease has the growth of the center city been
greater than its saborbs.16
The trek of popalation into the saborbs has brooght
a vast namber of problems. The qaestion "By what process
does a modern or ban commanity grow and renew itself?*' is
not the subject content of this paper.17 However, some
pertinent comments may be cited, fhos, the increased
mobility of the popalation is a pertinent factor in per
mitting the family to live considerable distances from the
Central Business District withoat job and other restric
tions. The factor of transportation was studied in Chicago
by C. W. Bresse, who studied the daily flow of population
between residence and the Central Business District.1^
The suburbs are composed basically of young couples
who desire a place of their own, which has space for their
expanding families. These families mean a wide market for
plants and shrubs, household goods, etc. Also, the people

in the saborhs tend to dress informally and do most of
their entertaining at home. This affects the demand for
clothing, furnitnre, and home appliances.
The ezodns of popalation to the snhorhs gives no
indication of snhsiding. It appears rather to he
increasing.20
V. STATISTICAL BITISIONS OF LOS AMCFLIS CÔOTTY
For statistical pnrposes, Los Angeles Conmty has
been divided in many ways depending apon the needs of the
organization doing the dividing.
Practically all the methods of divisions ased for
Los Angeles Coanty are based on the Censas Tract. These
tracts are grouped into whatever manner will best salt the
tabulation of data needed. Of basic importance is the fact
that boundaries have not changed since their adoption in
1940. Where popalation in a particular tract had become
too great (normal between 3>000 and 6,000) since 1940,
the tract in 1950 was divided into parts and numbered
accordingly.

Methods used to divide Los Angeles County for major
statistical purposes have included: 1. Census of Business
Areas; 2. Employment Areas; 3* Metropolitan Welfare Areas; j

4. Sales Control Areas; 5* Statistical Areas ; 6 . Welfare |
Planning Council Study Areas,^3 |
For the purpose of this paper, the Statistical Areas
established by the Los Angeles County Regional Planning
Commission will be used. Since 1940, the Commission has
published quarterly population estimates for these
statistical areas.% These estimates are the basis for
the relationships which were computed by the writer.

A search of the literature failed to reveal any
study directly along the lines of this report. However,
one study on the geographical distribution of population
density in Philadelphia is reported to have been made.^3

DESIGNATION OP BOIMDARIES
Within Los Angeles Goanty there are forty-five large
anâ small incorporated cities intermingling with, and even
snrroanding, unincorporated areas. The largest of these is
Los Angeles City. This county, with 4,083 square miles,
{about the size of Connecticut or New Jersey) is a vast
area with great contrasts.^ Because of the considerable
intra-county difference, which exist, the collection of
statistics on a county-wide basis is not satisfactory for
many of the agencies which use such statistics. Therefore,
some means is needed to divide this area into smaller more
workable units. The geographical divisions used generally
differ, but are all built up by using groupings of the same
basic unit, the Census Tract.
I. CENSUS TRACTS OP LOS ANGELES COUNTY
In 1940, the Los Angeles County Regional Planning
Commission finished the final details whereby, with the
consent of various other local bodies expressing interest
in the problem, it submitted to the United States Census
^Elisabeth R. Prank, director. Background for
Planning (Los Angeles: Research Department^ Welfare
Planning Council, 1955), p. 4.
151
j
Bureau maps sàowimg the exact outer boundaries of 590 {
tracts into which Los Angeles Oounty was to be divided.^
The United States Bureau of the Gensus accepted these and
thus the official tracts used in the 1940 population count
were established.
For the 1950 Census it was found necessary to
divide some tracts into two or more parts. In these eases,
suffixes were added to the established tract number for
each part; thus 115 became 115A and 115B. Because of this
and other subdivisions, Los Angeles County Census Tracts
were increased from the original 590 to 793» which includedi
363 tracts within the City of Los Angeles. Indications are
that, by I960, census tracts in the County will be expanded
to some 1,@0C.3
In this study the whole population of each census
tract has been assigned to one particular segment in one
quadrant. Where a census tract actually lies in two or
more segments and/or quadrants, the writer has assigned the
whole of the tract's population to that segment and
quadrant which contained the largest portion of the tract's
area.

Regional Planning Commission, Los Angeles County, 1940),

II. STATISTICAL ARMS OF LOS AHOILIS GOUHTY
At the same time as the Los Angeles County Regional
Planning Commission established bonndaries for census
tracts it also established statistical areas, with 93 such
areas in the County. Boundaries of statistical areas
followed, without deviation, the boundaries of the outer
census tracts contained therein.^
Starting in 1940, the Regional Planning Commission
published quarterly estimates of population for each of the
statistical areas. The writer obtained these population
estimates for January, April, July, and Cctober for each of
the ensuing years, with the exception of 1951 and 1952, for
which only the January figures were available. Just after
January, 1951, the population and dwelling unit estimates
were discontinued until January, 1952, and then discon
tinued again until January, 1953*5
F^en though the Wnited States decennial census of
population was taken in April, 1950, the January, 1951
data, of the Regional Planning Commission, did not reflect
fully corrections in accordance with the census figures.
^«Los Angeles County Census Tracts,* loo, cit.
^"Population and Dwelling Units," (Los Angeles:
Regional Planning Commission, Los Angeles County, 1951),
No. 37*
17
though they did show preliminary corrections. Also, the
County was still divided by the original 93 statistical
areas, which contained the census tracts of 1940.
Beginning with the January, 1952 report, the County 1
jwas divided into 134 statistical areas based on the 793 I
census tracts of 1950, which is illustrated in Figure 1,
page 19. This was done in part so data could be directly
applied to Census of Business Areas without apportionment
or prorating as required in the past.& As an example.
Statistical Area 9.1 was split into Statistical Area 9.11
and 9.12.
In general the estimated population figures are
derived from dwelling unit figures times a "population per
dwelling unit" factor, which is continuously kept up-to-
date (by guestimate). The dwelling unit figures are run
ning totals obtained through the use of building permits
for new dwelling units, moves, alterations, etc., applied
as net additions to the United States Census data.7
The "population per dwelling unit" factor will
differ from area to area. Wherever there is some question
as to the figure to use the population is underestimated,
^"Population and Dwelling Units," op. cit., (1952),
No. 38.
7lbld.. (1954), No. 40.
18
rather than the reverse, so as to he oonservative. The
figure for individual statistical areas are believed to be
I correct within 4 to 5 per cent, but the total for the
ICounty is believed to be correct within 1 per cent, likely
j
I on the conservative side.®
III. QÜABRAOTS A m SlCMfflTS
That part of Los Angeles County has been studied
which is circumscribed by a circle of fourteen mile radius
drawn with its center at Sixth and Main Street in the
Central Business District of Los Angeles City. This circle
has been divided into four quadrants. These have in turn
been divided into segments of two miles width. The circle,
quadrants, and segments have been drawn in on a map of Los
Angeles County and are shown as Figure 1.

for the seven segments used, in each of the four quadrants,
and in four quadrants combined. (The figures correspond
to the slope of a straight line fitted to a plot on
logarithmic paper of the logarithm of population versus
time.) Rate of change can be most easily obtained by
reference to compound interest tables.5

CHAPTER V
GRAPHIC PRESENTATION 01 POPULATION GROWTH
I. POPULATION GROWTH OF LOS ANGELES COUNTY
The estimated population of Los Angeles County, for
January 1, of each year, for the period 1946 to 1956, has
been graphed in Figure 2, page 27# The population of the
County has increased at an annual rate of 5 per cent in the
period 1950 to 1956. For 1946 to 1950, the rate averaged
5 1/2 per cent yearly.
The jogs noted in Figure 2, and throughout the
graphs presented, represents statistical adjustment
following the census periods of 1950 and 1953, (year of
special United States Census), rather than actual popu
lation jogs.
II. POPULATION DENSITY FOR APRIL 1, 1956
Figure 3, page 28, shows the population density for
April 1, 1956, for the four quadrant combined, from the
point of origin to fourteen miles out. The points fall on
a straight line, in proportion to distance from the Central
Business District. Distance for each segment is taken
arbitrarily to be the average of the inner and outer radii
which delineate the segment.
26
III. KATE OF POPULATION GROWTH BY QUADRANTS AND SEGMENTS
Pigares 9 throagh 43, pages 104 through 138, shows
population growth, for the period 1946 to 1956, for
individual segments, for each quadrant, and for four
quadrants combined from the point of origin to a distance
of fourteen miles out from the Central Business District
Figures 4 through 8, pages 29 through 33, are plots
of annual rate of change of population of segments versus
their distance from the Central Business District. ;
Within Los Angeles County the San Garbriel Mountainsj
influence growth in the segments lying between 8 to 14
I
miles from the Central Business District in Quadrant l; |
the Santa Monica Mountains likewise influence growth in
Quadrant II. The latter have apparently not exercised as
strong an influence as the former, as can be seen in Table
3, page 24 .

The objective of this thesis was to ascertain
I whether a mathematical relationship existed between popu
lation density and/or growth over the years and distance
from the Central Business District of Los Angeles City.
Accordingly, population growth in Los Angeles County was
studied in relation to distance, up to fourteen miles from
this Central Business District. A circle with radius of
fourteen miles was circumscribed on a map of Los Angeles
County, with Sixth and Main Street as its center. The
circle was divided into four quadrants, with each quadrant
sub-divided into seven segments, eaeh of two miles width.
The population of each segment in each quadrant and
for four quadrants combined, for January 1, of each year,
for the period 1946 to 1956, was determined from detailed
estimates published by the Los Angeles County Regional
Planning Commission.
The following conclusions were reached.
(1) County population increased at a steady rate
each year of 5 1/2 per cent over the proceeding year, in
the period 1946 to 1950; and at a steady rate each year of
5 per cent over the previous year, in the period 1951 to
See Figure 2, page 27#
35
(2) Density of popalation decreases in proportion
to the logarithm of distance from the Central Easiness
District of Los Angeles City. See Figaro 3, page 28.
(3) Rate of growth of population increases in
I direct proportion to distance from the Central Business
i
District of Los Angeles City. See Figure 8, page 33.

Abstract (if available)

Abstract During the past three decades there has been an increasing interest in population -- its numbers, its make-up or composition, its distribution in space, and the changes therein, and its growth. This interest in population is not misplaced as the population faots and changes are most intimately bound up with the immediate welfare of individuals, and from a broader standpoint with the masses. Also, reliable information must be on hand because it is essential to effective administration and appraisal of many activities of government. Varied information on population growth and its geographic distribution is also needed by the business community, and by civic and welfare organizations. All these must base their future activities, in some part, on projections of future population, and its distribution. A considered appraisal of underlyingrelationships and trends, based upon careful evaluation of past and present, is basic to projection of the future.
