An Essay on the Principle of Population

by T. R. Malthus

The population of the thirteen American States before the war was reckoned at about three millions. Nobody imagines that Great Britain is less populous at present for the emigration of the small parent stock that produced these numbers. On the contrary, a certain degree of emigration is known to be favourable to the population of the mother country. It has been particularly remarked that the two Spanish provinces from which the greatest number of people emigrated to America, became in consequence more populous. Whatever was the original number of British emigrants that increased so fast in the North American Colonies, let us ask, why does not an equal number produce an equal increase in the same time in Great Britain? The great and obvious cause to be assigned is the want of room and food, or, in other words, misery, and that this is a much more powerful cause even than vice appears sufficiently evident from the rapidity with which even old states recover the desolations of war, pestilence, or the accidents of nature. They are then for a short time placed a little in the situation of new states, and the effect is always answerable to what might be expected. If the industry of the inhabitants be not destroyed by fear or tyranny, subsistence will soon increase beyond the wants of the reduced numbers, and the invariable consequence will be that population which before, perhaps, was nearly stationary, will begin immediately to increase.

The fertile province of Flanders, which has been so often the seat of the most destructive wars, after a respite of a few years, has appeared always as fruitful and as populous as ever. Even the Palatinate lifted up its head again after the execrable ravages of Louis the Fourteenth. The effects of the dreadful plague in London in 1666 were not perceptible fifteen or twenty years afterwards. The traces of the most destructive famines in China and Indostan are by all accounts very soon obliterated. It may even be doubted whether Turkey and Egypt are upon an average much less populous for the plagues that periodically lay them waste. If the number of people which they contain be less now than formerly, it is, probably, rather to be attributed to the tyranny and oppression of the government under which they groan, and the consequent discouragements to agriculture, than to the loss which they sustain by the plague. The most tremendous convulsions of nature, such as volcanic eruptions and earthquakes, if they do not happen so frequently as to drive away the inhabitants, or to destroy their spirit of industry, have but a trifling effect on the average population of any state. Naples, and the country under Vesuvius, are still very populous, notwithstanding the repeated eruptions of that mountain. And Lisbon and Lima are now, probably, nearly in the same state with regard to population as they were before the last earthquakes.

CHAPTER 7

A probable cause of epidemics—Extracts from Mr Suessmilch's tables—Periodical returns of sickly seasons to be expected in certain cases—Proportion of births to burials for short periods in any country an inadequate criterion of the real average increase of population—Best criterion of a permanent increase of population—Great frugality of living one of the causes of the famines of China and Indostan—Evil tendency of one of the clauses in Mr Pitt's Poor Bill—Only one proper way of encouraging population—Causes of the Happiness of nations—Famine, the last and most dreadful mode by which nature represses a redundant population—The three propositions considered as established.

By great attention to cleanliness, the plague seems at length to be completely expelled from London. But it is not improbable that among the secondary causes that produce even sickly seasons and epidemics ought to be ranked a crowded population and unwholesome and insufficient food. I have been led to this remark, by looking over some of the tables of Mr Suessmilch, which Dr Price has extracted in one of his notes to the postscript on the controversy respecting the population of England and Wales. They are considered as very correct, and if such tables were general, they would throw great light on the different ways by which population is repressed and prevented from increasing beyond the means of subsistence in any country. I will extract a part of the tables, with Dr Price's remarks.

IN THE KINGDOM OF PRUSSIA, AND DUKEDOM OF LITHUANIA

10 Yrs to 1702 21,963 14,718 5,928 37 to 10 150 to 100
5 Yrs to 1716 21,602 11,984 4,968 37 to 10 180 to 100
5 Yrs to 1756 28,392 19,154 5,599 50 to 10 148 to 100
"N.B. In 1709 and 1710, a pestilence carried off 247,733 of the
inhabitants of this country, and in 1736 and 1737, epidemics prevailed,
which again checked its increase."

It may be remarked, that the greatest proportion of births to burials, was in the five years after the great pestilence.

6 yrs to 1702 6,540 4,647 1,810 36 to 10 140 to 100
6 yrs to 1708 7,455 4,208 1,875 39 to 10 177 to 100
6 yrs to 1726 8,432 5,627 2,131 39 to 10 150 to 100
6 yrs to 1756 12,767 9,281 2,957 43 to 10 137 to 100
"In this instance the inhabitants appear to have been almost doubled in
fifty-six years, no very bad epidemics having once interrupted the
increase, but the three years immediately follow ing the last period
(to 1759) were so sickly that the births were sunk to 10,229 and the
burials raised to 15,068."

Is it not probable that in this case the number of inhabitants had increased faster than the food and the accommodations necessary to preserve them in health? The mass of the people would, upon this supposition, be obliged to live harder, and a greater number would be crowded together in one house, and it is not surely improbable that these were among the natural causes that produced the three sickly years. These causes may produce such an effect, though the country, absolutely considered, may not be extremely crowded and populous. In a country even thinly inhabited, if an increase of population take place, before more food is raised, and more houses are built, the inhabitants must be distressed in some degree for room and subsistence. Were the marriages in England, for the next eight or ten years, to be more prolifick than usual, or even were a greater number of marriages than usual to take place, supposing the number of houses to remain the same, instead of five or six to a cottage, there must be seven or eight, and this, added to the necessity of harder living, would probably have a very unfavourable effect on the health of the common people.
