Required fields are marked *. The increase of population will take place, if unchecked, in a geometric progression, while the means of subsistence will increase in only an arithmetic progression. That means they refer to any kind of crisis or disaster that reduces the population’s average lifespan. Updates? According to Walker, “The Malthusian theory is applicable to all communities without consideration of colour and place.

In most modern economies, birth-rates have declined as the standard of living has increased.

Thus the world population stood at 1.6 billion in 1900 which further took 60 years to double to 3 billion in 1960. Widely read for such works as Political Justice (1793), Godwin took for granted the perfectibility of humankind and looked to a millennium in which rational people would live prosperously and harmoniously without laws and institutions. In 1804 Malthus married Harriet Eckersall, and in 1805 he became a professor of history and political economy at the East India Company’s college at Haileybury, Hertfordshire. That means, the more food is available, the more people can be sustained. Importance of Malthusian Theory of Population. Malthus was an economic pessimist, viewing poverty as man’s inescapable lot. He then pointed out that larger families can produce even more offspring in the following generation, and so on, which causes the population to grow exponentially. The time taken by a population to double its size with a particular annual growth rate is called doubling time. For example, the price of wheat in the United States, adjusted for inflation, has fallen by about two-thirds in the last 200 years. In an approach less rigorous than Ricardo’s, Malthus discussed the problem of price determination in terms of an institutionally determined “effective demand,” a phrase that he invented.

(5) Population not related to Food Supply but to Total Wealth: The Malthusian theory rests on a weak relationship between population and food supply. In 1798 Thomas Malthus published anonymously An Essay on the Principle of Population. Then it took only 350 years for doubling.

Advanced machinery, fertilizers, pesticides, and more resilient seeds have increased food production at a much higher rate than Malthus had predicted. Title page of an 1806 edition of Thomas Malthus's. It acted as a brake on economic optimism, helped to justify a theory of wages based on the wage earner’s minimum cost of subsistence, and discouraged traditional forms of charity. Malthus assumed that an increase in the standard of living would result in an increase in the birth-rate and thus accelerate population growth.

For example, historically speaking population of world was 200 million at the time of birth of Christ which doubled in 1400 years.


That means, whenever the standard of living rises, people will produce more children and the size of families increases.

During the middle of 1980 in 20th century when the growth rate of the world was 1.8 percent the doubling time was 39 years.

For example, if every family had four kids, the population could, in theory, double with every new generation. Although the global population has increased significantly over the past centuries, the growth rates in most modern economies have turned out to be much lower than predicted by Malthus. The theory is based on an essay on the Principle of Population, written by Thomas Robert Malthus, an English economist, in 1798. Examples of preventive checks include abstinence before marriage, birth control, or delaying marriage and kids until there are sufficient financial means to support them. But there were critics who thought that the theory was too pessimistic. However, because the availability of food necessarily limits the size of the population, this leads to a so-called Malthusian catastrophe (a.k.a., Malthusian crisis or Malthusian crunch) that brings the population back down to its maximum possible size. Despite all the criticism, the Malthusian theory is very important in the annals of human geography.

Condorcet, and Other Writers.The work received wide notice. This is the basis of the optimum theory of population. Thus, Malthus predicted that even with the help of technological advances, it wouldn’t be possible to increase food production beyond a linear growth rate in the long run. It states that the population grows geometrically, while its food supply only increases arithmetically. The […]

In fact, the right relationship is between population and total wealth of the country. He continued publishing a variety of pamphlets and tracts on economics. The Malthusian theory was hypothesized by Thomas Robert Malthus wherein he established that population increase is exponential in nature if left unchecked or uncontrolled while food production is only arithmetical thus, the disparity among the two element will lead to a problem of scarcity and catastrophe in the likely future.

Only “vice” (including “the commission of war”), “misery” (including famine or want of food and ill health), and “moral restraint” (i.e., abstinence) could check this excessive growth.
