Density is what
overturns a
pyramid

A population pyramid pits age against numbers.

[

]

By looking at one, you can instantly tell whether the

population is young

or old, or whether the growth rate is increasing

(

)

. The older a population gets,

the

more it is guaranteed to decrease

because one phenomenon feeds on the other. The process is self-

sustaining

and exponential. The older a population, the

fewer children it has. A dearth of children, in turn,

results in an

older population. The dearth of children coupled with better

health and living conditions

leads to a geologically

swift aging of the population which leads to further declines in the birth

rate.

Fig. 1 The population pyramid overturns

What we are witnessing today is the geologically swift overturning of the global population pyramid. An

urban population

ages for several reasons, among them:

Women stop procreating as a result of density, a consequence in turn of socio-

economic reasons

Adults enjoy better living conditions and access to health services. Therefore, the

majority

individuals live up to their natural life spans. In the past, this wasn’t

possible because disease

and poor living conditions cut life short.

The reproductive age bracket is squeezed from two sides

(

Figs.

and

)

. The

average age of

first pregnancy rises as women postpone having families until

they

can afford children or until

they can fit them in their busy schedules. As the

population increases and becomes older, women

in the reproductive age bracket

become a smaller percentage of the population. Since individuals

have fewer

children, the average age at which they have their last child decreases. Agrarian

women died young and on the average had children towards the end of their lives.

Urban women

live twice as long and end up having children somewhere near the

middle of their lives.

These factors have led the average age of the world population to increase dramatically in the last couple

of decades and

promises to continue doing so in the very near future. Demographers have estimated that

at the

start of the Christian era the

average age of the world population was probably around 16. There

were

relatively few old people and lots of young people.

Many children died before reaching puberty. This

level

changed little over the next few centuries. By the year 2000, however,

the average age of the world

population

was around 27. This average is expected to climb to 40 in just three or four decades

(

)

Best 71 offers a

parallel trend: longevity. He tells us that life expectancy in the Roman Empire was about

22. By 1800,

it had

climbed to about 40. Today it is closer to 80. These statistics indicate that the pyramid

is overturning rapidly in

geological terms

(

A population pyramid depicts the population mix. It pits young versus old and males versus
females. A young population is characterized by a pyramid with a broad base and thin apex.
This is the case of tiny, agrarian populations of which a good example is the Greek city state.
An old population has a narrow base and a broad apex. This is the case with Man today. In
new species, the population rises and most individuals are below the reproductive age
bracket. In old species, population declines and most individuals are above the reproductive
age bracket.

In the 19th Century, most people still lived in rural areas and the population
was young. Late in the 20th Century, Man became an urban species (we
nucleated in cities and abandoned the land to agri-corporations). The
average age of the population has risen dramatically and will continue to
do so as women stop procreating. Our species will soon attain ZPG and,
subsequently, we can expect population to decline. Unless we can
stimulate fertility again, this leads to extinction. What will get us to jump-
start birthing again?

A young population is characterized by a broad base and a narrow
apex. As fertility drops and longevity increases, the population mix
suffers a transformation. Gradually, there are ever older people and
fewer young. This leads to a population pyramid overturn, in part,
because the reproductive age bracket is compressed in relation to
global population.

It is unlikely that the reproductive age bracket remains constant
throughout the lifetime of a species, but, because population
increases swiftly towards the end of its life cycle, it is impossible
for the age bracket to rise significantly in such a short geological
period of time to make any difference.

In the past, the global
population was quite
young. It is estimated that
the average age in the
Roman Empire hovered
around 16 or 17. In the year
2000, this number climbed
to 27, and in only 30 or 40
more years it is expected
to jump dramatically to 40
