One further reason that people avoid discussing population is a kind of nagging
fear that their personal economic well-being is dependent on continuing population
growth. On the contrary, there are substantial reasons to believe that falling
population would economically benefit most people. We will conclude two things:
In times of stable or falling population there are three fundamental economic forces
that would benefit most people.
* Fewer people would compete for jobs. The infrastructure for manufacturing
and the service sector for our large population is in place and corporations will
not easily abandon these investments. Therefore jobs will continue to be available
and their availability will contract more slowly than the population. Thus,
it would become easier to find good jobs at every level. As a result, pay scales
across the board will rise.
* Fewer people would be vying to purchase products and services - food, health
insurance, electronics, and luxury items alike. Therefore, prices would drop
and previously unaffordable goods would fall within the budget of a wider range
of people. This is again true because of existing investment in plant and capacity.
* The per capita availability of virtually every "natural" or non-renewable
resource would rise, from grazing land to minerals and energy sources. This
increased abundance would result in a cost drop, in effect a dividend, for consumers
and end users.
Economists can't test the effects of these forces by scientific experiment,
but here are three historical examples that suggest that
falling population leads to greater prosperity for the general population.
1. In the mid-14th century, population dropped as the result of several waves
of Plague deaths. For decades thereafter, the workers of the day enjoyed higher
wages, greater freedom of movement, more freedom from forced labor, and even
something approaching a political voice (as in the
2. More recently, in the 1970's the Chinese government initiated a strong birth
control policy which has dramatically slowed population growth. It is striking
that within one generation, China has moved from a third world peasant economy
to become a powerful economic force in the industrialized world. It seems highly
unlikely that such a transition could have happened so quickly (if at all) had
the birthrate continued to hover around 3.3 instead of the current 1.7.
3. Currently, most European countries have falling populations. While it is
too early to see the long-term economic consequences of this, it is encouraging
that in the past five years, employment levels and payscale are both rising
in most countries with falling population.
Individual Prosperity and Economic Growth: Are they the same?
If it is such a distinct possibility that we would be economically better off
with a lower or falling population, how is it that conventional economic thinking
so often links individual prosperity to growth? One of the most frequent and
important words in business and investing is "growth." And practically
every politician running for office promises to bring us "economic growth"
and by implication, individual prosperity. But most people don't really understand
whether "growth" is good for most of us, or whether it is instead
is bringing us closer to a future few of us would really choose if we understood
Measuring Economic Growth
One problem we face in disentangling this is the measure that is usually used
in this country as a stand-in for economic well-being, the Gross Domestic Product
(GDP). GDP measures the total value of goods and services produced during a
given time period. Thus, goods such as pharmaceuticals, software, and houses
and the services provided by physicians, architects, and police all comprise
However, the GDP does not measure most individuals' financial well-being. There
are several reasons for this.
* Negative Aspects of the GDP
An increase in the GDP is usually viewed positively, for a growing economy is
widely believed to be a healthy economy. But this is a misunderstanding of the
GDP. In fact, the GDP measures how bad, as well as how good, things are. During
an epidemic, for instance, the GDP might rise because expenditures for medication,
medical care, and hospitalization increase dramatically. Or after a natural
disaster, the GDP might rise due to the cost of disaster-relief goods and services,
and then reconstruction. But under such circumstances, rising GDP is clearly
not an indicator of rising individual prosperity for most people.
Likewise, on an everyday level, it is difficult to imagine how individual prosperity
rises when more Internet pornography is sold, more bombs and warplanes are built,
gas prices soar, and new prisons are built. Yet each of these events contributes
to the GDP.
* Numeric Problems with GDP
Two straightforward matters of computing GDP make it unsuited to measuring most
people's economic well-being.
The first is that when population is rising as it is at present, a rising GDP
may simply reflect the larger economy to service more people. It doesn't make
much sense to celebrate a GDP rising at 2% if population is rising at a similar
The second is the "Bill Gates in the stadium" phenomenon. If Bill
Gates walks into a football stadium with 46,500 fans in it, the average net
worth of everyone in the stadium rises by $1,000,000. Those 46,500 people aren't
any better off even though their average net worth has risen so much. Likewise
if a hundred people in the country get $10 billion each and the other 280 million
people lose $3,500 each, the total assets of the country rises, but 280 million
people are actually worse off than they were before. Something like this
happened in the "economic recovery" of the 2002-2007
when GDP rose at a respectable 4.2 percent rate, but real median
household income fell.
* What's Missing from GDP
Likewise, GDP fails to take into account at least four categories of items which
have significant value, but are external to the ordinary ways of economic analysis.
1) One of these is the value of unexploited resources. For instance, during
the gold rush era, the gold was already in the ground. It had a potential value
like the potential energy an object. People choose to mine it and convert that
potential into a current economic transaction. But we no longer have that potential.
Most of us value the future and, given the choice, would wish to leave a good
world to our children and great-great grandchildren. It would be hard to consider
ourselves economically prosperous if we knew that by our actions, we had doomed
our children to a life of bare subsistence food and water, crammed in
high rise dwellings, facing endless congestion, with limited access to recreation,
beaches and mountains.
When an individual spends the capital he or she has, it shows up as an increase
in GDP, but that may or may not indicate an improvement in that person's economic
2) The next externalities are natures services. Forests purify our air and
replenish our oxygen, the sea replenishes our fisheries, rivers and the earth
have traditionally recycled our waste products, the earth provides the topsoil
in which we grow our crops. The GDP does not include these "free"
services which nature provides, and so does not register a decline when our
activities interfere with them. Our population has risen to the point where
the earth's resources, like the seemingly infinite availability of water and
the ability to process our waste products, are strained and must be included
in our economic calculations.
3) The third of these is the loss of many positive features of our lives which the rising
population is taking away. When a factory or a mall is built in an open field
next to your house, you lose the view, the sunlight and air circulation, and
you lose the access to open space. Each of these things has value to people.
In my town, a view might add $100,000 to $200,000 (or much more) to the value
of a house. This economic value of open space has been in the news recently
in New Hampshire as more and more people buy second homes in formerly rural
regions to escape the congestion of the cities and suburbs. As a result, tax
assessments have been rising dramatically, adding
one case $140,000 to a property's underlying value of $22,900. A large warehouse
built next door would of course increase the GDP but would take that value straight
off all the nearby properties. That loss of value would not be measured in GDP.
Other features like traffic congestion, living close to work, living close
to recreational areas like parks, lakes and the ocean, also have an economic
value, as seen in the value of housing with these features. Yet, as population
increases, malls, factories, warehouses and housing developments are built, which
subtract these values from the existing houses in the region. These economic
losses are not computed in GDP, although they are very real losses to the individuals
who are affected by so-called "growth."
4) The final element excluded from the GDP is the value of unpaid
labor. The classic example of this is childcare. If the provider of childcare
in a two-parent household returns to work, someone must be hired to provide
childcare. The cost of this then shows up as an increase in GDP. However, some
two-parent families are financially worse off, or only marginally better off,
when both are working. GDP rises by the value of the second salary, the clothing
and transportation required for work and the childcare, and yet the family economic
unit is worse off, or perhaps only slightly better off. Unpaid labor is not
a small effect. Some estimates are about one third of the GDP, or about $4 trillion
Better Measures of Individual Prosperity
The GDP is to some extent the lowest common denominator of the economy, the
dollar value of all transactions. But when GDP does not bear a direct relationship
to the economic well being of most people, we can see that the bar has been
set too low. Because of these limitations, many groups around the world have
proposed alternative measures. The General Progress Index (GPI) and the Index
of Sustainable Economic Welfare (ISEW) are two of the better known ones. They
both include indicators of environmental and social well being, as well as traditional
economic measures like GDP. The United Nations uses the Human Development Index,
and recently the nation of Bhutan was in the news for adopting an index of Gross
National Happiness. Even Real Median Household Income is more indicative of
general well being than the GDP, and it is noteworthy that there has been a
significant divergence between these measures in the past five years. (Read
more about alternatives to the GDP in our Resources
Each of these alternative measures makes useful contributions by including
various features that people value, but which are not measured by the GDP. However,
none of these measures has caught on as replacement measure for the overall
health of our economy. To some extent, the reasons for this are political.
Each measure includes factors that represent the values of the group which is
proposing it, and inevitably some of these values are not easily acceptable
to other stakeholders in the economic process. So if we are going to build momentum
to replace GDP with something more representative of most individuals' economic
prosperity, we will have to find ways of building consensus among these diverse
One way to do this is to convene a forum to debate and define the meaning of
individual prosperity, and to rally political support for computing and reporting
this index. Features such as financial security, excellent schools, accessible
green space, good housing, access to healthcare, our expected well-being 40
years from now, and the well being of our great-grandchildren, would be combined
into a metric of economic prosperity, which we might call the Prosperity Index
(PI). Our goal is that the federal government would calculate and release the
PI every month and that news reports would focus on this number as more germane
than the GDP.
Presumably, thinking about the economy in terms of increasing the individual
prosperity of most people will have many benefits. First among them of course
will be nudging public policy makers towards increasing the general prosperity
of the people of our country. But from the perspective of our focus on population,
we expect that this measure will make it clear that rising population is having
negative effects on most people in the country.
We find there is little reason for most people to fear the economic effects
of falling population. On the contrary, there are substantial reasons to believe
that stable or falling population would be economically beneficial throughout most of
the world, from relieving the starvation-level shortages of food, water and
health care in the highly overpopulated regions of the world, to halting the
gradual loss of amenities in the more prosperous regions of the developed world.
One step in making this process clear to people is to build consensus for focusing
on an economic measure which is indicative of individual prosperity.
