Thomas Robert Malthus, after whom Malthusianism is named. Malthusianism is a theory that population growth is potentially exponential, according to the Malthusian growth model, while the growth of the food supply or other resources is linear, which eventually reduces living standards to the point of triggering a population decline.
The neo-Malthusian controversy, comprising related debates of many years later, has seen a similar central role assigned to the numbers of children born. [27] 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. [ 28 ]
Malthusian models have the following form: = where P 0 = P(0) is the initial population size, r = the population growth rate, which Ronald Fisher called the Malthusian parameter of population growth in The Genetical Theory of Natural Selection, [2] and Alfred J. Lotka called the intrinsic rate of increase, [3] [4]

At one lecture, he condemned drunkenness and prostitution as alienating, degrading, and impoverishing. Although he was sometimes identified as a socialist, his solution to the problem was decidedly Malthusian in advocating birth control, which he would defend to the end of his life. Wicksell has been described as an "ardent neo-Malthusian." [4]
Boserup is known for her theory of agricultural intensification, also known as Boserup's theory, which posits that population change drives the intensity of agricultural production. Her position countered the Malthusian theory that agricultural methods determine population via limits on food supply .
