In his 1798 book ''[[An Essay on the Principle of Population]]'', Malthus observed that an increase in a nation's food production improved the well-being of the population, but the improvement was temporary because it led to population growth, which in turn restored the original [[per capita]] production level. In other words, humans had a propensity to use abundance for population growth rather than for maintaining a high [[standard of living]], a view and stance that has become known as the "[[Malthusian trap]]" or the "Malthusian spectre".  Populations had a tendency to grow until the lower class suffered hardship, want, and greater susceptibility to war, [[famine]], and [[disease]], a pessimistic view that is sometimes referred to as a [[Malthusian catastrophe]]. Malthus wrote in opposition to the popular view in 18th-century Europe that saw society as improving and in principle as perfectible.<ref>Geoffrey Gilbert, introduction to Malthus T.R. 1798.

== Early life and education ==
Thomas Robert Malthus was the sixth of seven children<ref name = "Robert Malthus ODNB"/> of Daniel Malthus and Henrietta Catherine, daughter of [[Daniel Graham (apothecary)|Daniel Graham]], apothecary to kings [[George II of Great Britain|George II]] and [[George III of Great Britain|George III]], and granddaughter of [[Thomas Graham (apothecary)|Thomas Graham]], apothecary to kings [[George I of Great Britain|George I]] and [[George II of Great Britain|George II]]. Henrietta was depicted alongside her siblings in [[William Hogarth]]'s painting, ''[[The Graham Children]]'' (1742).<ref>The Tate Gallery: An Illustrated Companion to the National Collections of British & Modern Foreign Art. London: Tate Gallery, 1979, p. 15</ref> Malthus was born at The Rookery, a "small elegant mansion" at [[Westcott, Surrey|Westcott]], near [[Dorking]] in [[Surrey]], which his father had bought—at that time called Chertgate Farm—and converted into "a gentleman's seat"; the family sold it in 1768 and moved to "a less extensive establishment at [[Albury, Surrey|Albury]], not far from [[Guildford]]". Malthus had a [[cleft lip and palate]] which affected his speech; such birth defects had occurred in previous generations of his family. His friend, the social theorist [[Harriet Martineau]], who was hard of hearing, nevertheless stated that due to his sonorous voice he was the only person she could hear well without her [[ear trumpet]].<ref>Martineau, Harriet 1877.

[[File:Malthus - Essay on the principle of population, 1826 - 5884843.tif|thumb|''Essay on the principle of population'', 1826]]
Malthus came to prominence for his 1798 publication, ''An Essay on the Principle of Population''. He wrote the original text in reaction to the optimism of his father and his father's associates (notably [[Jean-Jacques Rousseau]]) regarding the future improvement of society. He also constructed his case as a specific response to writings of [[William Godwin]] (1756–1836) and of the Marquis de Condorcet (1743–1794). His assertions evoked questions and criticism, and between 1798 and 1826 he published six more versions of ''An Essay on the Principle of Population'', updating each edition to incorporate new material, to address criticism, and to convey changes in his own perspectives on the subject.

The '''Malthusian controversy''' to which the ''Essay'' gave rise in the decades following its publication tended to focus attention on the birth rate and marriage rates. The '''neo-Malthusian controversy''', comprising related debates of many years later, has seen a similar central role assigned to the numbers of children born.<ref>{{cite book|first=G.

The goal of Malthusian theory is to explain how population and food production expand, with the latter experiencing arithmetic growth and the former experiencing exponential growth.<ref>{{cite book |last1=Walter |first1=R |title=Malthus Across Nations |date=2020 |publisher=Edward Elgar Publishing. |chapter=Malthus's principle of population in Britain: restatement and antiquation}}</ref>  The controversy, however, concerns the relevance of Malthusian theory in the present world.

== Travel and further career ==
In 1799, Malthus made a European tour with [[William Otter]], a close college friend, travelling part of the way with [[Edward Daniel Clarke]] and [[John Marten Cripps]], visiting Germany, Scandinavia and Russia. Malthus used the tour to gather population data. Otter later wrote a ''Memoir'' of Malthus for the second (1836) edition of his ''Principles of Political Economy''.<ref>{{cite DNB|wstitle=Otter, William|volume=42}}</ref><ref>{{cite ODNB|id=20935|title=Otter, William|first=Arthur|last=Burns}}</ref> During the [[Peace of Amiens]] of 1802 he travelled to France and Switzerland, in a party that included his relation and future wife Harriet.<ref>{{cite book|first1=Jean-Antoine-Nicolas|last1=de Caritat Condorcet (marquès de)|author-link1=Marquis de Condorcet|first2=William|last2=Godwin|author-link2=William Godwin|first3=Thomas Robert|last3=Malthus|editor-first=John|editor-last=Avery|title=Progress, Poverty and Population: Re-Reading Condorcet, Godwin and Malthus|url=https://books.google.com/books?id=ZA0lNlvbh0sC&pg=PA64|date=1997|publisher=[[Routledge]]|location=Abingdon, England|isbn=978-0-7146-4750-0|page=64}}</ref>

In 1803, he became rector of [[Walesby, Lincolnshire]].<ref name="ReferenceA"/>

In 1805, Malthus became Professor of History and Political Economy at the [[East India Company College]] in [[Hertfordshire]].<ref>Malthus T. R. 1798. ''The Essay of the Population Principle''. Oxford World's Classics reprint: xxix, Chronology.</ref> His students affectionately referred to him as "Pop", "Population", or "web-toe" Malthus.

Near the end of 1817, the proposed appointment of [[Graves Champney Haughton]] to the college was made a pretext by Randle Jackson and [[Joseph Hume]] to launch an attempt to close it down. Malthus wrote a pamphlet defending the college, which was reprieved by the East India Company within the same year, 1817.<ref>{{cite book|author=Thomas Robert Malthus|title=T.R.

In 1818, Malthus became a Fellow of the [[Royal Society]].

== Malthus–Ricardo debate on political economy ==
During the 1820s, a setpiece intellectual discussion took place among the exponents of [[political economy]], often called the Malthus–Ricardo debate after its leading figures, Malthus and theorist of [[free trade]] [[David Ricardo]], both of whom had written books with the title ''Principles of Political Economy''. Under examination were the nature and methods of political economy itself, while it was simultaneously under attack from others.<ref>{{cite book|first=Mary|last=Poovey|author-link=Mary Poovey|title=A History of the Modern Fact: Problems of Knowledge in the Sciences of Wealth and Society|url=https://books.google.com/books?id=Cf7ProAtFBkC&pg=PA295|date=1998|publisher=[[University of Chicago Press]]|location=Chicago, Illinois|isbn=978-0-226-67525-1|page=295}}</ref> The roots of the debate were in the previous decade. In ''The Nature of Rent'' (1815), Malthus had dealt with [[economic rent]], a major concept in classical economics. Ricardo defined a theory of rent in his ''Principles of Political Economy and Taxation'' (1817): he regarded rent as value in excess of real production—something caused by ownership rather than by free trade. Rent therefore represented a kind of negative money that landlords could pull out of the production of the land, by means of its scarcity.<ref>''On The Principles of Political Economy and Taxation'', London: John Murray, Albemarle-Street, by David Ricardo, 1817 (third edition 1821)&nbsp;– Chapter 6, On Profits: paragraph 28, "Thus, taking the former ..." and paragraph 33, "There can, however ..."</ref> Contrary to this concept, Malthus proposed rent to be a kind of [[economic surplus]].<ref>{{Cite web|url=http://www.d.umn.edu/cla/faculty/jhamlin/4111/Malthus/Thomas%20Robert%20Malthus.htm|title=Thomas Robert Malthus|website=www.d.umn.edu|access-date=2019-11-19}}</ref>

The debate developed over the economic concept of a [[general glut]], and the possibility of failure of [[Say's law]]. Malthus laid importance on [[economic development]] and the persistence of [[disequilibrium (economics)|disequilibrium]].<ref name="S193">Sowell, pp. 193–4.</ref> The context was the [[Post-Napoleonic depression|post-war depression]]; Malthus had a supporter in [[William Blake (economist)|William Blake]], in denying that [[capital accumulation]] (saving) was always good in such circumstances, and [[John Stuart Mill]] attacked Blake on the fringes of the debate.<ref>{{cite book|first=Donald|last=Winch|author-link=Donald Winch|title=Riches and Poverty: An Intellectual History of Political Economy in Britain, 1750–1834|url=https://archive.org/details/richespovertyint0000winc|url-access=registration|access-date=14 June 2013|date=26 January 1996|publisher=[[Cambridge University Press]]|location=Cambridge, England|isbn=978-0-521-55920-1|page=[https://archive.org/details/richespovertyint0000winc/page/365 365]}}</ref>

Ricardo corresponded with Malthus from 1817 about his ''Principles''. He was drawn into considering political economy in a less restricted sense, which might be adapted to legislation and its multiple objectives, by the thought of Malthus. In ''Principles of Political Economy'' (1820) and elsewhere, Malthus addressed the tension, amounting to conflict he saw between a narrow view of political economy and the broader moral and political plane.<ref name="ColliniWinch1983">{{cite book|author1=Stefan Collini|author2-link=Donald Winch|author2=Donald Winch|author3-link=John Wyon Burrow|author3=John Wyon Burrow|title=That Noble Science of Politics: A Study in Nineteenth Century Intellectual History|url=https://books.google.com/books?id=E688AAAAIAAJ&pg=PA65|date=1983|publisher=CUP Archive|isbn=978-0-521-27770-9|page=65|author1-link=Stefan Collini}}</ref> [[Leslie Stephen]] wrote:

<blockquote>If Malthus and Ricardo differed, it was a difference of men who accepted the same first principles. They both professed to interpret [[Adam Smith]] as the true prophet, and represented different shades of opinion rather than diverging sects.<ref name="Stephen2006">{{cite book|author=Leslie Stephen|title=The English Utilitarians|url=https://books.google.com/books?id=-QKLMdbt5JIC&pg=PA238|date=2006|publisher=Continuum International Publishing Group|isbn=978-0-8264-8816-9|page=238|volume=1|author-link=Leslie Stephen}}</ref></blockquote>

It is now considered that the different purposes seen by Malthus and Ricardo for political economy affected their technical discussion, and contributed to the lack of compatible definitions.<ref name="S193"/> For example, [[Jean-Baptiste Say]] used a definition of production based on [[goods and services]] and so queried the restriction of Malthus to "goods" alone.<ref>{{cite book|author=Samuel Hollander|title=Jean-Baptiste Say and the Classical Canon in Economics: The British Connection in French Classicism|url=https://books.google.com/books?id=IZdF-SECz9cC&pg=PA170|date=2005|publisher=Taylor & Francis|isbn=978-0-203-02228-3|page=170}}</ref>

In terms of public policy, Malthus was a supporter of the [[economic protectionism|protectionist]] [[Corn Laws]] from the end of the [[Napoleonic Wars]]. He emerged as the only economist of note to support duties on imported grain.<ref>Geoffrey Gilbert, introduction to Malthus T.R. 1798. ''An Essay on the Principle of Population''. Oxford World's Classics reprint. xx in Oxford World's Classics series. xx</ref> By encouraging domestic production, Malthus argued, the Corn Laws would guarantee British [[self-sufficiency]] in food.<ref>Cannan E. 1893.

== Later life ==
Malthus was a founding member in 1821 of the [[Political Economy Club]], where [[John Cazenove]] tended to be his ally against Ricardo and Mill.<ref>{{cite book|author=Thomas Robert Malthus|title=Principles of Political Economy|url=https://books.google.com/books?id=qjs1DUxjFr8C&pg=PR58|date=1989|publisher=Cambridge University Press|isbn=978-0-521-24775-7|page=lxviii}}</ref> He was elected in the beginning of 1824 as one of the ten royal associates of the [[Royal Society of Literature]]. He was also one of the first fellows of the [[Statistical Society]], founded in March 1834.

In 1827, he published ''Definitions in Political Economy''<ref>{{cite book|last1=Malthus|first1=Thomas Robert|title=Definitions in Political Economy Preceded by an Inquiry into the Rules which Ought to Guide Political Economists in the Definition and Use of Their Terms, with Remarks on the Deviation from These Rules in Their Writings|url=https://archive.org/details/definitionsinpo00maltgoog|date=1827|publisher=John Murray|location=London}}</ref> The first chapter put forth "Rules for the Definition and Application of Terms in Political Economy". In chapter 10, the penultimate chapter, he presented 60 numbered paragraphs putting forth terms and their definitions that he proposed should be used in discussing political economy following those rules. This collection of terms and definitions is remarkable for two reasons: first, Malthus was the first economist to explicitly organize, define, and publish his terms as a coherent glossary of defined terms; and second, his definitions were for the most part well-formed definitional statements. Between these chapters, he criticised several contemporary economists—[[Jean-Baptiste Say]], [[David Ricardo]], [[James Mill]], [[John Ramsay McCulloch]], and [[Samuel Bailey]]—for sloppiness in choosing, attaching meaning to, and using their technical terms.<ref name="Definitions in Political Economy">{{cite book|last1=Malthus|first1=Thomas Robert|title=Definitions in Political Economy|date=2016|publisher=Berkeley Bridge Press|location=McLean|isbn=978-1-945208-01-0|url=http://www.politics-prose.com/book/9781945208010}}</ref>

McCulloch was the editor of ''The Scotsman'' of Edinburgh and replied cuttingly in a review printed on the front page of his newspaper in March 1827.<ref>{{cite journal|last1=McCulloch|first1=John Ramsay|title=A Review of Definitions in Political Economy by the Rev. T. R. Malthus|journal=The Scotsman|date=1827-03-10|page=1}}</ref> He implied that Malthus wanted to dictate terms and theories to other economists. McCulloch clearly [[wikt:whose ox is gored|felt his ox gored]], and his review of ''Definitions'' is largely a bitter defence of his own ''Principles of Political Economy'',<ref>{{cite book|last1=McCulloch|first1=John Ramsay|title=The Principles of Political Economy|date=1825|publisher=William & Charles Tait|location=Edinburgh}}</ref> and his counter-attack "does little credit to his reputation", being largely "personal derogation" of Malthus.<ref>Morton Paglin's "Introduction" to: {{cite book|last1=Malthus|first1=Thomas Robert|title=Definitions in Political Economy|date=1986|publisher=Augustus M.

This motivation of Malthus's work was disregarded by McCulloch, who responded that there was nothing to be gained "by carping at definitions, and quibbling about the meaning to be attached to" words. Given that statement, it is not surprising that McCulloch's review failed to address the rules of chapter 1 and did not discuss the definitions of chapter 10; he also barely mentioned Malthus's critiques of other writers.<ref name="Definitions in Political Economy"/>

== Family ==
On 13 March 1804, Thomas Malthus married Harriet Eckersall, the eldest daughter of his first cousins John and Catherine Eckersall, who lived near Bath. Harriet became well-known at Haileybury College for hosting gatherings of notable scientists; eleven years younger than Thomas, she survived him by thirty years, remarrying after his death.<ref>{{cite book |last1=Knowlton |first1=Charles |last2=Besant |first2=Annie |editor1-last=Chandrasekhar |editor1-first=S |title=Reproductive Physiology and Birth Control |date=2002 |publisher=Routledge |location=New York |pages=4–6}}</ref>

The couple had a son, Henry, and two daughters, Emily and Lucille. Henry, the eldest, became vicar of [[Effingham, Surrey]] in 1835 and of [[Donnington, West Sussex|Donnington, Sussex]] in 1837; he married Sofia Otter (1807–1889), daughter of Bishop [[William Otter]] and died in August 1882, aged 76.

== ''An Essay on the Principle of Population'' ==
{{main|An Essay on the Principle of Population}}
Malthus argued in his ''Essay'' (1798) that population growth generally expanded in times and in regions of plenty until the size of the population relative to the primary resources caused distress:
{{blockquote|Yet in all societies, even those that are most vicious, the tendency to a virtuous attachment [i.e., marriage] is so strong that there is a constant effort towards an increase of population. This constant effort as constantly tends to subject the lower classes of the society to distress and to prevent any great permanent amelioration of their condition.|Malthus, T.&nbsp;R. 1798. ''An Essay on the Principle of Population.'' Chapter II, p. 18 in [[Oxford World's Classics]] reprint.}}

Malthus argued that two types of checks hold population within resource limits: ''positive'' checks, which raise the death rate; and ''preventive'' ones, which lower the birth rate. The positive checks include hunger, disease and war; the preventive checks: [[birth control]], postponement of marriage and [[celibacy]].<ref>Geoffrey Gilbert, introduction to Malthus T.R. 1798. ''An Essay on the Principle of Population''. Oxford World's Classics reprint. viii</ref>

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 society|pre-industrial societies]]. These findings are the basis for neo-Malthusian modern mathematical models of ''long-term historical dynamics''.<ref>See, e.g., [[Peter Turchin]] 2003; [http://cliodynamics.info/PDF/Turchin_Korotayev_SEH_2006.pdf Turchin and Korotayev 2006] {{webarchive|url=https://web.archive.org/web/20120229202712/http://cliodynamics.info/PDF/Turchin_Korotayev_SEH_2006.pdf |date=29 February 2012 }}; Peter Turchin et al. 2007; [[Andrey Korotayev|Korotayev]] et al. 2006.</ref>

Malthus wrote that in a period of resource abundance, a population could double in 25 years. However, the margin of abundance could not be sustained as population grew, leading to checks on population growth:
{{blockquote|If the subsistence for man that the earth affords was to be increased every twenty-five years by a quantity equal to what the whole world at present produces, this would allow the power of production in the earth to be absolutely unlimited, and its ratio of increase much greater than we can conceive that any possible exertions of mankind could make it ... yet still the power of population being a power of a superior order, the increase of the human species can only be kept commensurate to the increase of the means of subsistence by the constant operation of the strong law of necessity acting as a check upon the greater power.|Malthus T. R. 1798. ''An Essay on the Principle of Population''. Chapter 2, p. 8<ref name="Oxford World's Classics reprint">Oxford World's Classics reprint</ref>}}In later editions of his essay, Malthus clarified his view that if society relied on human misery to limit population growth, then sources of misery (''e.g.'', hunger, disease, and war) would inevitably afflict society, as would volatile economic cycles. On the other hand, "preventive checks" to population that limited birthrates, such as later marriages, could ensure a higher standard of living for all, while also increasing economic stability.<ref>Essay (1826), I:2. See also A:1:17</ref> Regarding possibilities for freeing man from these limits, Malthus argued against a variety of imaginable solutions, such as the notion that agricultural improvements could expand without limit.<ref>{{Cite book|url=https://books.google.com/books?id=9-q_SSfE6skC&pg=PA5 |title=An Essay on the Principle of Population (Two Volumes in One)|last=Malthus|first=Thomas Robert|date=2011-12-01|publisher=Cosimo, Inc.|isbn=9781616405700|pages=5–11|language=en}}</ref>

Of the relationship between population and economics, Malthus wrote that when the population of laborers grows faster than the production of food, real wages fall because the growing population causes the [[cost of living]] (''i.e.'', the cost of food) to go up. Difficulties of raising a family eventually reduce the rate of population growth, until the falling population again leads to higher real wages.

In the second and subsequent editions Malthus put more emphasis on ''moral restraint'' as the best means of easing the poverty of the lower classes."<ref>Geoffrey Gilbert, introduction to Malthus T.R. 1798. ''An Essay on the Principle of Population''. Oxford World's Classics reprint, p. xviii</ref>

== Other works ==

=== 1800: ''The present high price of provisions'' ===
In this work, his first published pamphlet, Malthus argues against the notion prevailing in his locale that the greed of intermediaries caused the high price of provisions. Instead, Malthus says that the high price stems from the [[Poor Laws]], which "increase the parish allowances in proportion to the price of corn." Thus, given a limited supply, the Poor Laws force up the price of daily necessities. However, he concludes by saying that in time of scarcity such Poor Laws, by raising the price of corn more evenly, actually produce a ''beneficial'' effect.<ref>1800: ''The present high price of provisions'', paragraph 26</ref>

=== 1814: ''Observations on the effects of the Corn Laws'' ===
Although government in Britain had regulated the prices of grain, the [[Corn Laws]] originated in 1815. At the end of the Napoleonic Wars that year, [[Parliament of the United Kingdom|Parliament]] passed legislation banning the importation of foreign corn into Britain until domestic corn cost 80 shillings per [[hundredweight|quarter]].{{clarify|date=April 2018}} The high price caused the cost of food to increase and caused distress among the working classes in the towns. It led to serious rioting in London and to the [[Peterloo Massacre]] in [[Manchester]] in 1819.<ref>{{cite book|first=Francis Wrigley|last=Hirst|title=From Adam Smith to Philip Snowden: a History of Free Trade in Great Britain|publisher=[[T.

In this pamphlet, printed during the parliamentary discussion, Malthus tentatively supported the free-traders. He argued that given the increasing cost of growing British corn, advantages accrued from supplementing it from cheaper foreign sources.

=== 1820: ''Principles of political economy'' ===
In 1820 Malthus published ''[[Principles of Political Economy (Malthus)|Principles of Political Economy]]''.
(A second edition was posthumously published in 1836.) Malthus intended this work to rival Ricardo's ''Principles'' (1817).<ref>See {{cite book|last=Malthus|first=Thomas Robert|year=1820|title=Principles of Political Economy Considered with a View of their Practical Application|edition=1|publisher=John Murray|publication-date=1820|location=London|url=https://books.google.com/books?id=b_dBAAAAcAAJ&pg=PR1}}</ref> It, and his 1827 ''Definitions in political economy'', defended [[Jean Charles Léonard de Sismondi|Sismondi]]'s views on "general glut" rather than Say's law, which in effect states "there can be no general glut".<ref>{{cite book|title=Jean-Baptiste Say: Critical Assessments of Leading Economists|volume=5|chapter=Say's Law and Keynesian Economics|first=Tyler|last=Cowen|date=2000|page=319}}</ref>

== Reception and influence ==
{{further|An Essay on the Principle of Population#Reception and influence}}
Malthus developed the theory of demand-supply mismatches that he called [[Overproduction|gluts]]. Discounted at the time, this theory foreshadowed later work by an admirer, [[John Maynard Keynes]].<ref>{{cite book|author1=Steven G. Medema|author2=Warren J.

The vast bulk of continuing commentary on Malthus, however, extends and expands on the "Malthusian controversy" of the early 19th century. In Ireland where (writing to [[David Ricardo|Ricardo]] in 1817) Malthus proposed that "to give full effect to the natural resources of the country a great part of the population should be swept from the soil into large manufacturing and commercial Towns",<ref>{{cite book|author=David Ricardo|date=1952|title=The Works and Correspondence of David Ricardo: Vol. 7.

In general, Dickens had some Malthusian concerns (evident in ''[[Oliver Twist]]'', ''[[Hard Times (novel)|Hard Times]]'' and other novels), and he concentrated his attacks on [[Utilitarianism]] and many of its proponents, like [[Jeremy Bentham]], whom he thought of, along with Malthus, as unjust and inhumane.<ref>{{cite book |last=Paroissien |first=David |title=A companion to Charles Dickens |url=https://books.google.com/books?id=rATJ49kDnj8C&pg=PA160 |year=2008 |publisher=John Wiley and Sons |isbn=978-1-4051-3097-4}}</ref>

At the end of the show, the revolution wins but the characters end up dying because water was not being conserved, unlike when the 'pee fee' was in place. The penultimate line is "Hail Malthus!"

== Epitaph ==
[[File:Epitaph of Thomas Malthus.jpg|thumb|The [[epitaph]] of Malthus just inside the entrance to [[Bath Abbey]]]]
The epitaph of Malthus in Bath Abbey reads [with commas inserted for clarity]:
<blockquote>Sacred to the memory of the Rev THOMAS ROBERT MALTHUS, long known to the lettered world by his admirable writings on the social branches of political economy, particularly by his essay on population.

One of the best men and truest philosophers of any age or country, raised by native dignity of mind above the misrepresentations of the ignorant and the neglect of the great, he lived a serene and happy life devoted to the pursuit and communication of truth, supported by a calm but firm conviction of the usefulness of his labors, content with the approbation of the wise and good.

His writings will be a lasting monument of the extent and correctness of his understanding.

The spotless integrity of his principles, the equity and candour of his nature, his sweetness of temper, urbanity of manners and tenderness of heart, his benevolence and his piety are the still dearer recollections of his family and friends.
Born 14 February 1766 – Died 29 December 1834.</blockquote>
