The book An Essay on the Principle of Population was first published anonymously in 1798, [1] but the author was soon identified as Thomas Robert Malthus.The book warned of future difficulties, on an interpretation of the population increasing in geometric progression (so as to double every 25 years) [2] while food production increased in an arithmetic progression, which would leave a ...
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.
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.
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. [1] Malthusian models have the following form: = where P 0 = P(0) is the initial population size,
Malthus also notes that the checks on the human population are more complicated than those on animals and plants. [25] Malthus explains, for example, that a human check on population growth is the conscious decision not to reproduce because of financial burden. [25] Malthus then explains that the main check on population growth is food.
Theory of population may refer to: Malthusianism, a theory of population by Thomas Malthus (1766–1834) An Essay on the Principle of Population, the book in which Malthus propounded his theory; Neo-Malthusian theory of Paul R. Ehrlich (born 1932) and others; Theory of demographic transition by Warren Thompson (1887–1973)
Using these techniques, Malthus' population principle of growth was later transformed into a mathematical model known as the logistic equation: = (), where N is the population size, r is the intrinsic rate of natural increase, and K is the carrying capacity of the population.
In the 20th century, population planning proponents have drawn from the insights of Thomas Malthus, a British clergyman and economist who published An Essay on the Principle of Population in 1798. Malthus argued that, "Population, when unchecked, increases in a geometrical ratio. Subsistence only increases in an arithmetical ratio." He also ...
