Key takeaways

  • Thomas Robert Malthus belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Thomas Robert Malthus to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Thomas Robert Malthus from memory before moving on to harder problems.

Reference excerpt

Thomas Robert Malthus (; 13/14 February 1766 – 29 December 1834) was an English economist, cleric, and scholar influential in the fields of political economy and demography. 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. Malthus considered population growth as inevitable whenever conditions improved, thereby precluding real progress towards a utopian society: "The power of population is indefinitely greater than the power in the earth to produce subsistence for man." As an Anglican cleric, he saw this situation as divinely imposed to teach virtuous behavior. Malthus wrote that "the increase of population is necessarily limited by subsistence", "population does invariably increase when the means of subsistence increase", and "the superior power of population repress by moral restraint, vice, and misery." Malthus criticised the Poor Laws for leading to inflation rather than improving the well-being of the poor. He supported taxes on grain imports (the Corn Laws). His views became influential and controversial across economic, political, social and scientific thought. Pioneers of evolutionary biology read him, notably Charles Darwin and Alfred Russel Wallace. Presidents Thomas Jefferson and James Madison read Malthus. Malthus's failure to predict the Industrial Revolution was a frequent criticism of his theories. Malthus laid the "theoretical foundation of the conventional wisdom that has dominated the debate, both scientifically and ideologically, on global hunger and famines for almost two centuries."

Early life and education Thomas Robert Malthus was the sixth of seven children of Daniel Malthus and Henrietta Catherine, daughter of Daniel Graham, apothecary to kings George II and George III, and granddaughter of Thomas Graham, apothecary to kings George I and George II. Henrietta was depicted alongside her siblings in William Hogarth's painting, The Graham Children (1742). Malthus was born at The Rookery, a "small elegant mansion" at 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, 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. William Petersen and John Maynard Keynes describe Daniel Malthus as "a gentleman of good family and independent means [...] [and] a friend of David Hume and Jean-Jacques Rousseau". Daniel Malthus was son of Sydenham Malthus, who was a clerk of Chancery and director of the South Sea Company; he was also "proprietor of several landed properties in the Home Counties and Cambridgeshire". Sydenham Malthus's father, Daniel, had been apothecary to King William and later to Queen Anne; Daniel's father, Rev. Robert Malthus, was appointed vicar of Northolt, Middlesex (now West London) under the regicide Cromwell, but "evicted at the Restoration"; he was described as "an ancient divine, a man of strong reason, and mighty in the Scriptures, of great eloquence and fervour, though defective in elocution", due to "a very great impediment in his utterance" which has been concluded to be likely to have been a cleft palate. The young Malthus received his education at the Warrington Academy from 1782, where he was taught by Gilbert Wakefield. Warrington was a dissenting academy, which closed in 1783. Malthus continued for a period to be tutored by Wakefield at the latter's home in Bramcote, Nottinghamshire. Malthus entered Jesus College, Cambridge, in 1784. While there, he took prizes in English declamation, Latin and Greek, and graduated with honours, Ninth Wrangler in mathematics. His tutor was William Frend. He took the MA degree in 1791, and was elected a Fellow of Jesus College two years later. In 1789, he took orders in the Church of England, and became a curate at Oakwood Chapel (also Okewood) in the parish of Wotton, Surrey.

Worked examples

Example 1 — a first encounter with Thomas Robert Malthus

Start with the simplest possible case. Write down what Thomas Robert Malthus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Thomas Robert Malthus before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Thomas Robert Malthus ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Thomas Robert Malthus

In research
Thomas Robert Malthus appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Thomas Robert Malthus in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Thomas Robert Malthus is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1766 births, 1834 deaths, 18th-century British economists, so understanding it makes those chapters shorter.
In everyday life
Look for Thomas Robert Malthus outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
