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.
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]
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.

A population is in Malthusian equilibrium when all of its production is used only for subsistence. Malthusian equilibrium is a locally stable and a dynamic equilibrium.
Malthusian Theory According to Malthus, population growth at some point must collide with shrinking returns [5] . It is all about arithmetic food supply and exponential population where increase in population and food supply can be balanced through the establishment of positive checks and preventive measures [6] .
The classical economists took the theory of the determinants of the level and growth of population as part of Political Economy. Since then, the theory of population has been seen as part of Demography. In contrast to the Classical theory, the following determinants of the neoclassical theory value are seen as exogenous to neoclassical economics:
Some have seen it more as an aspiration, successfully realised in the short term by the commitment to the principles of subsidiarity and solidarity (built into financially independent local cooperatives and small family businesses).
