Does a healthy economy require
a growing population? Would slower population growth hurt business or threaten
workers’ jobs? Would it help? How would the average person fare in economic
terms if the rate of population growth approached zero?*

We have conducted research to
determine what effects different rates of population growth are likely to have
on the economic well-being of the nation. We compared the effects of the
2-child population projection with the effects of the 3-child projection. Our
overall conclusions from this research are:
1. Major economic changes are
on the horizon regardless of future changes in population growth rates.
2. The nation has nothing ‘to
fear from a gradual approach to population stabilization.
3. From an economic point of
view, a reduction in the rate of population growth would bring important
benefits, especially if the United States develops policies to take advantage
of the opportunities for social and economic improvement that slower population
growth would provide.
Income
Between now and the year 2000,
increases in the productivity of workers are likely to result in such a large
rise in average income that styles of life in the year 2000 will be
qualitatively different from what they are today. It is expected that by the
year 2000 average family income, now about $12,000, will exceed S21,000, in
terms of today’s dollars.1 This is the projection, even if the work
week were reduced to 30 hours, and even if the population grew at the 3-child
rate.
The average individual’s
consumption is expected to be more than twice what it is today, whether the
population grows at the 2-child or the 3-child rate. As income increases,
people show an increased preference for services, such as education and health
services, as compared with manufactured goods. So, the population of the year
2000 will boost its consumption of services faster than its consumption of
manufactured goods.
The rate of population growth
will have a significant effect on per capita income. Our research indicates
that in the year 2000, per capita income may be as much as 15 percent higher
under the 2-child than under the 3-child population growth rate. The main
reason for the higher per capita income under the 2-child projection is the
shift in the age composition resulting from slower population growth; as we saw
earlier, people of working age will constitute a larger fraction of the total
population under conditions of slower population growth. A secondary reason is
that with lower birthrates the percentage of women in the labor force is
expected to rise somewhat faster than it would otherwise. Taken together, these
trends mean relatively more workers and earners, and relatively fewer mouths to
feed.
The age effect arises from the
fact that population replaces itself from the bottom up; and, if it is growing,
it is adding more and more at the base of the age pyramid. However, growth in
the population of working age is drawn from the smaller numbers of births that
occurred 15 to 20 years earlier. When growth slows, it slows first at the base,
and before long we see a narrowing of the difference between the number of
births and the numbers annually entering the working ages. The ratio of workers
to youthful dependents rises, the income they produce is spread among fewer
people, and the average income available per person in the population
consequently increases.
Of course, the same process
eventually causes a rise in the percentage of old people in the
population—those who have passed working age. But because of higher death rates
at these ages, the increase in aged dependency offsets only part of the decline
in youth dependency, and the overall result is still a major drop in total
dependency and an increase in income available per person in the population.
Economic
Growth and the Quality of Life
The use of income or output per
capita as an indicator of the quality of life has been criticized on a number
of grounds. One such criticism is made by people who are concerned about
environmental deterioration. They maintain that higher output levels for the
economy as a
whole will cause a greater drain on natural resources and more
pollution.
Accordingly, we examined the
effects that the 2-and 3-child growth rates would have on GNP—the gross
national product—which measures the total volume of goods and services
produced. GNP is expected to more than double by the year 2000, whether the
population grows rapidly or slowly.2 This is the prospect implied by
the projected increases in per capita income and the further growth of
population resulting from the baby boom.
However, if families average
three children in the future, GNP will grow far more than if they average two
children. In the year 2000, the difference in GNP resulting from different
population assumptions amounts to as much as one-fourth of the total GNP today.
Rapid population growth will cause more rapid growth in the size of the
economy, and correspondingly greater demands on resources and the environment.
People will not be better off economically with more rapid population growth—we
have already seen that income per person is higher under the slower population
growth assumption. Rather, increases in the number of people simply multiply
the volume of goods and services produced and consumed. In the next chapter, we
examine the meaning of these trends for resource consumption and deterioration
of the environment.
Poverty
Income or output per capita is
an average, and it conceals some gross disparities. We need to be concerned
with these, especially at the lower end of the income scale—the people in
poverty.
We have estimated the effects
that slower population growth would have on poverty in the United States in the
year 2000. We have found that the general improvement in average income
associated with slower population growth would assist in reducing poverty, but
would not eliminate it. This is not good enough.
There are today, by official
estimate, 26 million Americans living in poverty conditions.3 This
is 13 percent of our population. Improvements in the average income of the
population do something for these groups, but not enough. Their problem is that
too many of them are not part of the system that generates and distributes
income.
Over six million poor people
are working adults who simply do not
make enough money to meet even the minimal official income standard. Over three
million of the poor are persons aged 14 to 64 who are sick or disabled, in
school, or unable to find work. Nearly five million are over age 65, and over
eight million are children. Finally, more than two million are female heads of
family whose responsibilities at home keep them from taking jobs.
What this adds up to is that
more than nine out of 10 poor people are excluded—because of age, incapacity,
poor training, family responsibilities, fiscal disincentives, or discrimination
in the labor market—from the system that produces and distributes income and
the things income buys. Real improvements in their lot will be reflected in a
changing distribution of income. But, while average income has risen
dramatically and the number of poor has declined as a result, the relative
distribution of income has changed little in the 25 years the Census Bureau has
been measuring it.
In a country as wealthy and
resourceful as ours, there is no excuse for permitting deprivation. For the
working poor and those who cannot find work, the solution is to eliminate
racial and sex discrimination in employment, and to improve education and
training. Beyond this, we need a serious reexamination of the status of the
aged. Old people are healthier and better educated than ever before. They are
often forced to stop working far before the end of their productive lives,
because of outright discrimination and outdated restrictions against older
workers, and because of fiscal disincentives against work built into our social
security laws and other pension arrangements.
Nevertheless, the country still
has a number of people who cannot be helped by better access to the labor
market. For these, the answer should be an increased public responsibility for
maintaining a decent standard of living.
Measures to achieve an improved
distribution of income should be beneficial demographically as well as
socially. Evidence indicates that levels of childbearing— both wanted and
unwanted—decline as income rises.
Labor Force
Growth
Thirty-five million new workers
will be seeking their first job in the decade of the 1970’s.4 That is seven
million more than in the 1960’s. This is one of the legacies of the baby boom.
As that generation comes of age, swelling numbers of job applicants put an extra
burden on full employment policy.
The pressure should be off in
the 1980’s. The number of new entrants to the labor force will probably be
close to the figure for the 1970’s, due to declining birthrates in the past
decade. Once all the new entrants and women resuming work after their children
are grown are balanced out against withdrawals through retirement and death,
the labor force in 1990 should number some 114 million, or 28 million more than
the 1970 figure.
What happens thereafter depends
mainly on the number of births in the 1970’s. If fertility should follow the
2-child projection, the number of people looking for their first job in the
1990’s should be about the same as in the 1980’s. However, if fertility follows
the 3-child projection, the number of job seekers in the 1990’s will jump 10
million, to a total of around 44 million; and by the year 2000, the total labor
force will number some 136 million. Beyond 2000, the difference in labor force
growth between the two projections becomes immense.
It seems clear that labor-force
trends under the 3-child projection can be expected to generate greater
pressure for increased production, employment, and consumption, and
correspondingly greater problems associated with the social and environmental
consequences of such increases. The 2-child projection does not imply that
these problems can be avoided, only that they will be less pressing. It implies
not only smaller numbers to be accommodated, but also a context in which the
urgency of competing priorities will be muted.
We have seen that slower
population growth causes a gradual increase in the percentage of old people and
a decline in the percentage of youth—hence, a rising average age of the
population. The same process also causes the labor force to age.
Concerns have been expressed
that an older labor force will lack the energy, flexibility, and imagination of
a younger one. Despite the absence of evidence for these concerns, their
existence is further reason to support programs desirable on other grounds,
such as the provision of continuing education to our labor force. Indeed, in
light of the rapid changes occurring in all aspects of life, the idea that
education should be completed by the age of 18, 22, or even 30, is clearly out
of date.
Business
Will a slower rate of
population growth hurt specific industries, particularly those which cater to
young people? Does it threaten jobs?
While it is certainly true that
there would be a faster increase in the sales of certain products, for example
baby foods and milk, under conditions of higher population growth, it is also
true that other products and services, for example convenience foods and
airline travel, would be relatively favored by the faster rise in per capita
income associated with slower population growth rates. More important, it does
not appear, for several reasons, that a lower population growth rate will cause
serious problems for any industry or its employees.5
First, regardless of the rate
of population growth, total income, and hence demand, will rise.
Second, slower population
growth will actually cause total as well as per capita income to be higher over
the next 10 to 15 years than would a more rapid population growth rate. In
other words, during the next 10 to 15 years total GNP in the 2-child projection
would probably be slightly larger than in the 3-child case.
Third, it is important to note
that under the 2-child family projection, there is no year in which there would
be fewer births than there were in 1971. In other words, a gradual approach to
population stabilization would not reduce demand from current levels for any
industry we studied. (We studied the effect of the 2-child and 3-child
population projections on demand for housing starts, mobile homes, domestic
cars, imported cars, men’s suits, frozen foods, power boats, credit, furniture
and household equipment, food and beverages, beer, clothing and shoes, steel,
dishwashers, railroad travel, and airline travel.)
Beyond the next 10 to 15 years,
the adjustments businesses must make to changes in consumer tastes and
technological developments should far exceed the problems of adjusting to a
lower population growth rate. The loom tender in the diaper factory is hurt
more by the competition from synthetic disposables than by the recent decline
in births. Large fluctuations in birthrates will require larger adjustments by
business than will small ones; still, we can have fluctuations around a 3-child
as well as a 2-child growth rate. In declining communities, small businesses
will not do as well economically as they would if there were more people
around—some adjustments will be required. But other changes that are
unpredictable today will require far more important adjustments by individuals,
as well as by entire industries.
Past experience should lead to
confidence that such adjustments can be made. Here is the Board Chairman of
Atlantic-Richfield, testifying at our public hearing in New York:
There is a habit of thinking in some segments
of the business community, of course, that population increase is somehow
essential to the maintenance of vigorous demand and economic growth, just as
there is an instinctive reaction against any important new cost factors being
added to the processes of production and distribution. But our economy has already,
and in many ways, shown its tremendous adaptability to new social demands and
necessities. I have not the slightest doubt that it can meet this new
challenge.6
The Growth
Mystique
In short, we find no convincing
economic argument for continued national population growth. On the contrary,
most of the plusses are on the side of slower growth. This finding is at
variance with much opinion, especially in the business community and among many
civic leaders. We have sought to find the reason for this seeming
contradiction.
Periods of rapid population
growth in this country have generally been periods of rapid economic expansion
as well. It is not surprising, therefore, that we associate population growth
with economic progress. However, the historical association of population
growth with economic expansion would be an erroneous guide to the formulation
of population policy for the future.
This connection reflects in
large part the fact that periods of rapid economic expansion attracted
immigrants to our shores and thus quickened population growth as a result.
Additions to population through immigration are far more stimulating to
economic growth than are additions by
natural increase. This is because, while babies remain dependent for many years
before beginning to contribute to output, many immigrants are of working age
and thus become immediately productive. Immigration made a major contribution
to rapid population growth up to World
War I, but its effect since then has been much diminished. In the years 1861 to
1910, the average annual immigration rate per 1,000 Americans was 7.5; the rate
for the period 1911 to 1970 dropped to 1.8. The rate for the recent period
reflects a rise from the 1930’s, when there was a net outflow of migrants, to
the 1960’s when the rate was 2.2.7
This answer may not satisfy the
gas station owner, ‘local food retailer, or banker, to whom it seems obvious
that “more people” means more customers or more savings accounts. Once again,
however, we need to examine the kind
of growth that means more business, and its relationship to local economic
expansion. The rapid local population growth that means more business results
chiefly from more people moving in, not more people being born and raised.
Adults moving in make ready customers and ready employees. They have grown up
elsewhere, their education has been paid for elsewhere, and being young, they
impose few of the ands of the dependent aged. Since mobile people are, on the
average, better qualified than those who do
move, it is no surprise that they provide an extra boost to local
establishments.
We have studied the effects of
lower national population growth rates on the economic well-being of urban and
rural areas within the nation. Is there reason to fear that the ills typical of
areas of population decline today would become more serious or widespread if
national population growth rates declined? We conclude that there is not; such
fears are based on a mistaken belief that population decline causes economic
decline. In reality, the chain of causation in distressed areas runs from (1)
the decline of regional competitive capability to (2) unemployment to (3) net
outmigration to (4) population loss.8 Accordingly, there is little
reason to suppose that local problems of unemployment or obsolescence of
physical facilities would be more serious in a situation of zero or negative
national population growth than they would be at any positive level of national
population growth. In the future, as in the past, areas of relatively high unemployment
will tend to be areas of relative population loss; but the relative population
loss will be the consequence and not the cause of local unemployment.
The diminished burden of
providing for dependents, and for the multiplication of facilities to keep up
with expanding population, should make more of our national output available
for many desirable purposes: new kinds of capital formation, including human
resources investment; public expenditure involving qualitative improvement and
modernization; and greater attention to environmental and amenity objectives.
Thus, whatever the future problems of urban areas and regions may be, we should
have more ample per capita resources to attack them in a situation with a lower
rate of population growth than we would have with a higher rate.
Summary
We have looked for, and have
not found, any convincing economic argument for continued national population
growth. The health of our economy does not depend on it. The vitality of
business does not depend on it. The welfare of the average person certainly
does not depend on it.
In fact, the average person
will be markedly better off in terms of traditional economic values if
population growth follows the 2-child projection rather than the 3-child one.
Slower growth will give us an older population, and this trend will require
adjustments well within the ability of the nation to provide. Beyond this.
however, we point out that the fruits of slower population growth will be
denied to those most in need of them unless deliberate changes are made in
distribution of income to those who lack it by reason of discrimination,
incapacity, or age.
