Malthusianism is the idea that population growth is potentially exponential while the growth of the food supply is linear. It derives from the political and economic thought of the Reverend Thomas Robert Malthus, as laid out in his 1798 writings, An Essay on the Principle of Population . Malthus believed there were two types of "checks" that in all times and places kept population growth in line with the growth of the food supply: "preventive checks", such as moral restraints (abstinence and delaying marriage until finances become balanced), and restricting marriage against persons suffering poverty or perceived as defective, and "positive checks", which lead to premature death such as disease, starvation and war, resulting in what is called a Malthusian catastrophe. The catastrophe would return the population to a lower, more "sustainable", level.Malthusianism has been linked to a variety of political and social movements, but almost always refers to advocates of population control.
A Malthusian growth model, sometimes called a simple exponential growth model, is essentially exponential growth based on the idea of the function being proportional to the speed to which the function grows. The model is named after Thomas Robert Malthus, who wrote An Essay on the Principle of Population (1798), one of the earliest and most influential books on population.
Thomas Robert Malthus was an English cleric and scholar, influential in the fields of political economy and demography.
The book An Essay on the Principle of Population was first published anonymously in 1798, but the author was soon identified as Thomas Robert Malthus. The book predicted a grim future, as population would increase geometrically, doubling every 25 years, but food production would only grow arithmetically, which would result in famine and starvation, unless births were controlled.
Neo-Malthusianism is the advocacy of population control programs to ensure resources for current and future populations.In Britain the term 'Malthusian' can also refer more specifically to arguments made in favour of preventive birth control, hence organizations such as the Malthusian League. Neo-Malthusians differ from Malthus's theories mainly in their enthusiasm for contraception. Malthus, a devout Christian, believed that "self-control" (abstinence) was preferable to artificial birth control. In some editions of his essay, Malthus allowed that abstinence was unlikely to be effective on a wide scale, thus advocating the use of artificial means of birth control as a solution to population "pressure". Modern "neo-Malthusians" are generally more concerned than Malthus with environmental degradation and catastrophic famine than with poverty.
Human reproduction planning is the practice of intentionally controlling the rate of growth of a human population. Historically, human population planning has been implemented with the goal of increasing the rate of human population growth. However, in the period from the 1950s to the 1980s, concerns about global population growth and its effects on poverty, environmental degradation and political stability led to efforts to reduce human population growth rates. More recently, some countries, such as China, Iran, and Spain, have begun efforts to increase their birth rates once again. While population planning can involve measures that improve people's lives by giving them greater control of their reproduction, a few programs, most notably the Chinese government's "one-child policy and two-child policy", have resorted to coercive measures.
The Malthusian League was a British organisation which advocated the practice of contraception and the education of the public about the importance of family planning. It was established in 1877 and was dissolved in 1927. The organisation was secular, utilitarian, individualistic, and "above all malthusian." The organisation maintained that it was concerned about the poverty of the British working class and held that over-population was the chief cause of poverty.
Malthusianism has attracted criticism from diverse schools of thought, including Marxistsand socialists, libertarians and free market enthusiasts, social conservatives, feminists and human rights advocates, characterising it as excessively pessimistic, misanthropic or inhuman. Many critics believe Malthusianism has been discredited since the publication of Principle of Population, often citing advances in agricultural techniques and modern reductions in human fertility. Many modern proponents believe that the basic concept of population growth eventually outstripping resources is still fundamentally valid, and "positive checks" are still likely in humanity's future if there is no action to curb population growth.
Libertarianism is a collection of political philosophies and movements that uphold liberty as a core principle. Libertarians seek to maximize political freedom and autonomy, emphasizing freedom of choice, voluntary association and individual judgment. Libertarians share a skepticism of authority and state power, but they diverge on the scope of their opposition to existing economic and political systems. Various schools of libertarian thought offer a range of views regarding the legitimate functions of state and private power, often calling for the restriction or dissolution of coercive social institutions.
In economics, a free market is a system in which the prices for goods and services are determined by the open market and by consumers. In a free market, the laws and forces of supply and demand are free from any intervention by a government or other authority and from all forms of economic privilege, monopolies and artificial scarcities. Proponents of the concept of free market contrast it with a regulated market in which a government intervenes in supply and demand through various methods such as tariffs used to restrict trade and to protect the local economy. In an idealized free-market economy, prices for goods and services are set freely by the forces of supply and demand and are allowed to reach their point of equilibrium without intervention by government policy.
Social conservatism is the belief that society is built upon a fragile network of relationships which need to be upheld through duty, traditional values and established institutions. This can include moral issues. Social conservatism is generally skeptical of social change, and believes in maintaining the status quo concerning social issues such as family life, sexual relations, and patriotism.
Malthus was not the first to outline the problems he perceived. The original essay was part of an ongoing intellectual discussion at the end of the 18th century regarding the origins of poverty. Principle of Population was specifically written as a rebuttal to thinkers like William Godwin and the Marquis de Condorcet, and Malthus's own father who believed in the perfectibility of humanity. Malthus believed humanity's ability to reproduce too rapidly doomed efforts at perfection and caused various other problems.
Poverty is not having enough material possessions or income for a person's needs. Poverty may include social, economic, and political elements.
William Godwin was an English journalist, political philosopher and novelist. He is considered one of the first exponents of utilitarianism and the first modern proponent of anarchism. Godwin is most famous for two books that he published within the space of a year: An Enquiry Concerning Political Justice, an attack on political institutions, and Things as They Are; or, The Adventures of Caleb Williams, an early mystery novel which attacks aristocratic privilege. Based on the success of both, Godwin featured prominently in the radical circles of London in the 1790s. He wrote prolifically in the genres of novels, history and demography throughout his life.
Marie Jean Antoine Nicolas de Caritat, Marquis of Condorcet, known as Nicolas de Condorcet, was a French philosopher and mathematician. His ideas, including support for a liberal economy, free and equal public instruction, constitutional government, and equal rights for women and people of all races, have been said to embody the ideals of the Age of Enlightenment and Enlightenment rationalism. He died in prison after a period of flight from French Revolutionary authorities.
His criticism of the working class's tendency to reproduce rapidly, and his belief that this, rather than exploitation by capitalists, led to their poverty, brought widespread criticism of his theory.
Malthusians perceived ideas of charity to the poor, typified by Tory paternalism, were futile, as these would only result in increased numbers of the poor; these theories played into Whig economic ideas exemplified by the Poor Law Amendment Act of 1834. The Act was described by opponents as "a Malthusian bill designed to force the poor to emigrate, to work for lower wages, to live on a coarser sort of food",which initiated the construction of workhouses despite riots and arson.
A Tory is a person who holds a political philosophy known as Toryism, based on a British version of traditionalism and conservatism, which upholds the supremacy of social order as it has evolved in the English culture throughout history. The Tory ethos has been summed up with the phrase "God, Queen, and Country". Tories generally advocate monarchism, and were historically of a high church Anglican religious heritage, opposed to the liberalism of the Whig faction.
Paternalism is action that limits a person's or group's liberty or autonomy and is intended to promote their own good. Paternalism can also imply that the behavior is against or regardless of the will of a person, or also that the behavior expresses an attitude of superiority. Paternalism, paternalistic and paternalist have all been used as a pejorative.
The Poor Law Amendment Act 1834 (PLAA), known widely as the New Poor Law, was an Act of the Parliament of the United Kingdom passed by the Whig government of Earl Grey. It completely replaced earlier legislation based on the Poor Law of 1601 and attempted to fundamentally change the poverty relief system in England and Wales. It resulted from the 1832 Royal Commission into the Operation of the Poor Laws, which included Edwin Chadwick, John Bird Sumner and Nassau William Senior. Chadwick was dissatisfied with the law that resulted from his report. The Act was passed two years after the 1832 Reform Act extended the franchise to middle class men. Some historians have argued that this was a major factor in the PLAA being passed.
Malthus revised his theories in later editions of An Essay on the Principles of Population, taking a more optimistic tone, although there is some scholarly debate on the extent of his revisions.According to Dan Ritschel of the Center for History Education at the University of Maryland,
The great Malthusian dread was that "indiscriminate charity" would lead to exponential growth in the population in poverty, increased charges to the public purse to support this growing army of the dependent, and, eventually, the catastrophe of national bankruptcy. Though Malthusianism has since come to be identified with the issue of general over-population, the original Malthusian concern was more specifically with the fear of over-population by the dependent poor.
One of the earliest critics was David Ricardo. Malthus immediately and correctly recognised it to be an attack on his theory of wages. Ricardo and Malthus debated this in a lengthy personal correspondence.
Another one of the 19th century critics of Malthusian theory was Karl Marx who referred to it as "nothing more than a schoolboyish, superficial plagiary of De Foe, Sir James Steuart, Townsend, Franklin, Wallace" (in Capital , see Marx's footnote on Malthus from Capital – reference below). Marx and Engels described Malthus as a "lackey of the bourgeoisie". [ citation needed ]Socialists and communists believed that Malthusian theories "blamed the poor" for their own exploitation by the capitalist classes, and could be used to suppress the proletariat to an even greater degree, whether through attempts to reduce fertility or by justifying the generally poor conditions of labour in the 19th century.
One proponent of Malthusianism was the novelist Harriet Martineau whose circle of acquaintances included Charles Darwin, and the ideas of Malthus were a significant influence on the inception of Darwin's theory of evolution.Darwin was impressed by the idea that population growth would eventually lead to more organisms than could possibly survive in any given environment, leading him to theorize that organisms with a relative advantage in the struggle for survival and reproduction would be able to pass their characteristics on to further generations. Proponents of Malthusianism were in turn influenced by Darwin's ideas, both schools coming to influence the field of eugenics. Henry Fairfield Osborn, Jr. advocated "humane birth selection through humane birth control" in order to avoid a Malthusian catastrophe by eliminating the "unfit".
Malthusianism became a less common intellectual tradition as the 19th century advanced, mostly as a result of technological increases, the opening of new territory to agriculture, and increasing international trade.Although a "conservationist" movement in the United States concerned itself with resource depletion and natural protection in the first half of the twentieth century, Desrochers and Hoffbauer write, "It is probably fair to say ... that it was not until the publication of Osborn’s and Vogt’s books  that a Malthusian revival took hold of a significant segment of the American population".

Malthusian theory is a recurrent theme in many social science venues. John Maynard Keynes, in Economic Consequences of the Peace, opens his polemic with a Malthusian portrayal of the political economy of Europe as unstable due to Malthusian population pressure on food supplies. [ citation needed ]Many models of resource depletion and scarcity are Malthusian in character: the rate of energy consumption will outstrip the ability to find and produce new energy sources, and so lead to a crisis.
In France, terms such as "politique malthusienne" ("Malthusian politics") refer to population control strategies. The concept of restriction of the population associated with Malthus morphed, in later political-economic theory, into the notion of restriction of production. In the French sense, a "Malthusian economy" is one in which protectionism and the formation of cartels is not only tolerated but encouraged.[ citation needed ]
Vladimir Lenin, the leader of the Bolshevik Party and the main architect of the Soviet Union was a critic of Neo-Malthusian theory (but not of birth control and abortion in general).
"Neo-Malthusianism" is a concern that overpopulation may increase resource depletion or environmental degradation to a degree that is not sustainable with the potential of ecological collapse or other hazards.[ citation needed ]
The rapid increase in the global population of the past century exemplifies Malthus's predicted population patterns; it also appears to describe socio-demographic dynamics of complex pre-industrial societies. These findings are the basis for neo-Malthusian modern mathematical models of long-term historical dynamics.
There was a general "neo-Malthusian" revival in the 1950s, 1960s, and 1970s after the publication of two influential books in 1948 (Fairfield Osborn's Our Plundered Planet and William Vogt's Road to Survival ). During that time the population of the world rose dramatically. Many in environmental movements began to sound the alarm regarding the potential dangers of population growth. xvi Other prominent Malthusians include the Paddock brothers, authors of Famine 1975! America's Decision: Who Will Survive?The Club of Rome published a book entitled The Limits to Growth in 1972. The report and the organisation soon became central to the neo-Malthusian revival. Paul R. Ehrlich has been one of the most prominent neo-Malthusians since the publication of The Population Bomb in 1968. Leading ecological economist Herman Daly has acknowledged the influence of Malthus on his concept of a steady-state economy. :
The neo-Malthusian revival has drawn criticism from writers who claim the Malthusian warnings were overstated or premature because the green revolution has brought substantial increases in food production and will be able to keep up with continued population growth. [ how? ] Responding to Simon, Al Bartlett reiterates the potential of population growth as an exponential (or as expressed by Malthus, "geometrical") curve to outstrip both natural resources and human ingenuity. Bartlett writes and lectures particularly on energy supplies, and describes the "inability to understand the exponential function" as the "greatest shortcoming of the human race".Julian Simon, a cornucopian, has written that contrary to neo-Malthusian theory, Earth's "carrying capacity" is essentially limitless.
Prominent neo-Malthusians such as Paul Ehrlich maintain that ultimately, population growth on Earth is still too high, and will eventually lead to a serious crisis.The 2007–2008 world food price crisis inspired further Malthusian arguments regarding the prospects for global food supply.
A Malthusian catastrophe is a prediction that population growth will outpace agricultural production – that there will be too many people and not enough food.
The Population Bomb is a best-selling book written by Stanford University Professor Paul R. Ehrlich and his wife, Anne Ehrlich, in 1968. It predicted worldwide famine in the 1970s and 1980s due to overpopulation, as well as other major societal upheavals, and advocated immediate action to limit population growth. Fears of a "population explosion" were widespread in the 1950s and 1960s, but the book and its author brought the idea to an even wider audience.
The iron law of wages is a proposed law of economics that asserts that real wages always tend, in the long run, toward the minimum wage necessary to sustain the life of the worker. The theory was first named by Ferdinand Lassalle in the mid-nineteenth century. Karl Marx and Friedrich Engels attribute the doctrine to Lassalle, the idea to Thomas Malthus's An Essay on the Principle of Population, and the terminology to Goethe's "great, eternal iron laws" in Das Göttliche.
Paul Ralph Ehrlich is an American biologist, best known for his warnings about the consequences of population growth and limited resources. He is the Bing Professor of Population Studies of the Department of Biology of Stanford University and president of Stanford's Center for Conservation Biology.
Population dynamics is the branch of life sciences that studies the size and age composition of populations as dynamical systems, and the biological and environmental processes driving them. Example scenarios are ageing populations, population growth, or population decline.
American environmental author Daniel Quinn coined the term Food Race to describe an understanding of the current overpopulation emergency as a perpetually escalating crisis between growing human population and growing food production, fueled by the latter. Quinn argues that as the worldwide human population increases, the typical international response is to more intensely produce and distribute food to feed these greater numbers of people. However, assuming that population increases according to increased food availability, Quinn argues that this response only ends up leading to an even larger population and thus greater starvation in the end. Therefore, Quinn's clear solution to the Food Race—to stop producing so much food—is not generally a common-sense or intuitive response; instead, it derives from seemingly counter-intuitive or "outside-the-box" thinking.
Social cycle theories are among the earliest social theories in sociology. Unlike the theory of social evolutionism, which views the evolution of society and human history as progressing in some new, unique direction(s), sociological cycle theory argues that events and stages of society and history generally repeat themselves in cycles. Such a theory does not necessarily imply that there cannot be any social progress. In the early theory of Sima Qian and the more recent theories of long-term ("secular") political-demographic cycles as well as in the Varnic theory of P.R. Sarkar an explicit accounting is made of social progress.
A doomer is someone who believes that the global problems of ecological exhaustion—such as overpopulation, climate change, and pollution–will cause the collapse of civilization, significant human population die-off, and even human extinction. They are alarmed that humanity's over-reliance on petroleum for agricultural and industrial productivity, along with government inaction will cause severe problems.
The Malthusian trap or population trap is a condition whereby excess population would stop growing due to shortage of food supply leading to starvation. It is named for Thomas Robert Malthus, who suggested that while technological advances could increase a society's supply of resources, such as food, and thereby improve the standard of living, the resource abundance would enable population growth, which would eventually bring the per capita supply of resources back to its original level. Some economists contend that since the industrial revolution, mankind has broken out of the trap. Others argue that the continuation of extreme poverty indicates that the Malthusian trap continues to operate. Others further argue that due to lack of food availability coupled with excessive pollution, developing countries show more evidence of the trap.
Human overpopulation is when there are too many people for the environment to sustain. In more scientific terms, there is overshoot when the ecological footprint of a human population in a geographical area exceeds that place's carrying capacity, damaging the environment faster than nature can repair it, potentially leading to an ecological and societal collapse. Overpopulation could apply to the population of a specific region, or to world population as a whole.
Biological exponential growth is the exponential growth of biological organisms. When the resources availability is unlimited in the habitat, the population of an organism living in the habitat grows in an exponential or geometric fashion. Population growth in which the number of individuals increase by a constant multiple in each generation. The potential for population growth can be demonstrated in the laboratory under conditions that provide abundant resources and space. For example, a few fruit flies in a large culture jar containing an abundant food source may reproduce rapidly. One female fruit fly may lay more than 50 eggs. Reproductive adults develop in about 14 days, with approximately equal numbers of male and female offspring. For each female that began the population, 50 flies are expected 2 weeks later. Each female in the second generation produces 50 more flies after 2 more weeks, and so on. In other words, the population is experiencing exponential growth. Slow exponential growth is when a population grows slowly yet exponential because the population has long live spans. While a rapid exponential growth refers to a population that grows rapidly because the population has short life spans.
Observations Concerning the Increase of Mankind, Peopling of Countries, etc. is a short essay written in 1751 by Benjamin Franklin. It was circulated by Franklin in manuscript to his circle of friends, but in 1755 it was published as an addendum in a Boston pamphlet on another subject. It was reissued ten times during the next 15 years.
Famine 1975! America's Decision: Who Will Survive? is a best-selling 1967 book by William and Paul Paddock. The brothers describe the rapidly growing population of the world, and a situation in which they believe it would be impossible to feed the entire global population within the short-term future. They believed that widespread famine would be the inevitable result, by 1975.
Theory of population may refer to:
The concept of the struggle for existence concerns the competition or battle for resources needed to live. It can refer to human society, or to organisms in nature. The concept is ancient, and the term struggle for existence was in use by the end of the 18th century. From the 17th century onwards the concept was associated with a population exceeding resources, an issue shown starkly in Thomas Robert Malthus’ An Essay on the Principle of Population which drew on Benjamin Franklin's Observations Concerning the Increase of Mankind, Peopling of Countries, etc..
Structural-Demographic Theory is a social-scientific theory that uses mathematical modeling to explain and predict outbreaks of political instability in complex societies. It originated in the work of American sociologist Jack Goldstone and has recently been developed further by Peter Turchin, Andrey Korotayev, Leonid Grinin and Sergey Nefedov.
