Section 5. NO EVIDENCE OF OVERPOPULATION

In a closed country, producing all its own necessities of life and

incapable of expansion, a high birth-rate would eventually increase the

struggle for existence and would lead to overpopulation, always provided

that, firstly, the high birth-rate is accompanied by a low death-rate, and

secondly, that the high birth-rate is maintained. For example, although

a birth-rate was high, a population would not increase in numbers if the

death-rate was equally high. Therefore, a high birth-rate does not of

necessity imply that population will be increased or that overpopulation

will occur. Again, if the birth-rate fell as the population increased,

the danger of overpopulation would be avoided without the aid of a high

death-rate. For a moment, however, let us assume that the Malthusian

premise is correct, that a high birth-rate has led to overpopulation, and

that the struggle for existence has therefore increased. Then obviously

the death-rate would rise; the effect of the high birth-rate would be

neutralised; and beyond a certain point neither the population nor the

struggle for existence could be further increased. On these grounds

Neo-Malthusians argue that birth-control is necessary precisely to obviate

that cruel device whereby Nature strives to restore the balance upset by a

reckless increase of births; and that the only alternative to frequent and

premature deaths is regulation of the source of life. As a corollary to

this proposition they claim that, if the death-rate be reduced, a country

is bound to become overpopulated unless the births are artificially

controlled. Fortunately it is possible to test the truth of this corollary,

because certain definite observations on this very point have been

recorded. These observations do not support the argument of birth

controllers.

(a) _In the Suez Canal Zone_

In the Suez Canal Zone there was a high death-rate chiefly owing to fever.

According to Malthus it would have been a great mistake to lower this

death-rate, because, if social conditions were improved, the population

would rapidly increase and exceed the resources of the country. Now, in

fact, the social conditions were improved, the death-rate was lowered, and

the subsequent events, utterly refuting the above contention, are thus

noted by Dr. Halford Ross, who was medical officer in that region:

"During the years 1901 to 1910, health measures in this zone produced a

very considerable fall in the death-rate, from 30.2 per thousand to

19.6 per thousand; the infant mortality was also reduced very greatly,

and it was expected that, after a lapse of time, the reduction of the

death-rate would result in a rise of the birth-rate, and a

corresponding increase of the population. _But such was not the case_.

When the death-rate fell, the birthrate fell too, and the number of the

population remained the same as before, even after nearly a decade had

passed, and notwithstanding the fact that the whole district had become

much healthier, and one town, Port Said, was converted from an

unhealthy, fever-stricken place into a seaside health resort." [6]

Moreover, Dr. Halford Ross has told me that artificial birth control

was not practised in this region, and played no part in maintaining a

stationary population. The majority of the people were strict Mohammedans,

amongst whom the practice of birth control is forbidden by the Koran.

(b) _In "Closed Countries" like Japan_

But a much more striking example of the population in a closed country

remaining stationary without the practice of birth control, thus refuting

the contention of our birth controllers, is to be found in their own

periodical, _The Malthusian_. [7] It would appear that in Japan from 1723

to 1846 the population remained almost stationary, only increasing from

26,065,422 to 26,907,625. In 1867 the Shogunate was abolished, the Emperor

was restored, and Japan began to be a civilised power. Now from 1872 the

population increased by 10,649,990 in twenty-seven years, and "during the

period between 1897 and 1907 the population received an increment of 11.6

per cent., whereas the food-producing area increased by only 4.4 per

cent.... According to Professor Morimoro, the cost of living is now so high

in Japan that 98 per cent, of the people do not get enough to eat." From

these facts certain obvious deductions may be made. So long as Japan was

a closed country her population remained stationary. When she became a

civilised industrial power the mass of her people became poorer, the

birth-rate rose, and the population increased, this last result being the

real problem to-day in the Far East. In face of these facts it is sheer

comedy to learn that our Malthusians are sending a woman to preach birth

control amongst the Japanese! Do they really believe that for over a

hundred years Japan, unlike most semi-barbaric countries, practised birth

control, and that when she became civilised she refused, unlike most

civilised countries, to continue this practice? There is surely a limit to

human credulity.

The truth appears to be that in closed countries the population remains

more or less stationary, that Nature herself checks the birth-rate without

the aid of artificial birth control, and that birthrates and death-rates

are independently related to the means of subsistence.
