The Malthusian theory of population, also known as the Malthusian population model, is a theory proposed by the English economist Thomas Malthus in the late 18th and early 19th centuries. The theory is based on the idea that population growth will always tend to outstrip the resources available to support it, leading to a state of overpopulation and ultimately, to population decline through starvation, disease, and other negative consequences.
According to Malthus, population growth occurs exponentially, while the production of food and other resources grows only arithmetically. This means that population growth will eventually outstrip the ability of the earth to support it, leading to a crisis of overpopulation. In order to prevent this crisis from occurring, Malthus believed that population growth must be controlled through the use of positive and preventive checks.
Positive checks refer to factors that increase mortality rates, such as disease, war, and famine. Preventive checks, on the other hand, refer to measures that reduce fertility rates, such as contraception, celibacy, and late marriage. Malthus argued that these checks were necessary in order to keep population growth in check and prevent overpopulation.
Despite the widespread acceptance of the Malthusian theory at the time it was proposed, it has since been largely rejected by the scientific community. This is due, in part, to the fact that Malthus failed to take into account the fact that human ingenuity and technological advances can lead to increased food production and other resources. In addition, Malthus's predictions about population growth have not come to pass, as population growth has slowed in many parts of the world, despite continuing increases in global population.
Despite its limitations, the Malthusian theory of population remains an important concept in the study of population dynamics and is often discussed in the context of population policy and resource management. While it may not accurately predict the future of population growth, it serves as a reminder of the importance of considering the long-term consequences of population growth and the need for responsible resource management.

Resource production can even be accelerated through industrialization, as Malthus was seeing during his own lifetime. However, Malthus, in later editions of his book, did not insist on these mathematical terms and only held that there was an inherent tendency in population to outrun the means of subsistence. The reality, however, has been that population growth has not itself created the crisis that Malthus predicted.

It is, however, to be regretted that population has been increasing at the wrong end. But by making rapid advances in technology and accumulating capital in larger quantity, advanced countries have been able to postpone the stage of diminishing returns.
The population fall due to the great wars was such great and all the science and medical human experiments had such a high toll of deaths that if all the people lost were still alive and all would have reproduced then the food production would be unable to cope even with all the advancement made. Again, agricultural production is not limited due to the advancement of science and technology. These are the principal findings. Coal only counts as our savior if we develop a means of utilizing it without the particle polution that it produces.

London: Cambridge University Press. In 1798, an English clergyman named Thomas Malthus made a dire prediction: He said the Earth could not indefinitely support an ever-increasing human population. In the mean time the cheapness of labour, the plenty of labourers, and the necessity of an increased industry amongst them, encourage cultivators to employ more labour upon their land; to turn up fresh soil, and to manure and improve more completely what is already in tillage; till ultimately the means of subsistence become in the same proportion to the population as at the period from which we set out.
