The following points highlight the top three theories of population. The Malthusian Theory of Population 2. The Optimum Theory of Population 3. The Theory of Demographic Transition. The Malthusian Theory of Population: Thomas Robert Malthus enunciated his views about population in his famous book, Essay on the Principle of Population as it affects the Future Improvement of Society, published in Malthus revolted against the prevailing optimism shared by his father and Godwin that a perfect state could be attained if human restraints could be removed.

Malthus objection was that the pressure of increasing population on the food supply would destroy perfection and there would be misery in the world. Malthus was severely criticised for his pessimistic views which led him to travel on the continent of Europe to gather data in support of his thesis.

He incorporated his researches in the second edition of his Essay published in The Malthusian theory explains the relationship between the growth in food supply and in population.

It states that population increases faster than food supply and if unchecked leads to vice or misery. The Malthusian doctrine is stated as follows: As a result, population increases in geometrical progression and if unchecked doubles itself every 25 years.

Thus starting from 1, population in successive periods of 25 years will be 1, 2, 4, 8, 16, 32, 64,after years. Thus the food supply in successive similar periods will be 1, 2, 3, 4, 5, 6, 7, 8, and 9 after years.

Thus an imbalance is created which leads to over-population. This is depicted in Figure 1. The food supply in arithmetical progression is measured on the horizontal axis and the population in geometrical progression on the vertical axis.

The curve M is the Malthusian population curve which shows the relation between population growth and increase in food supply.

It rises upward swiftly. The preventive checks are applied by a man to control the birth rate. They are foresight, late marriage, celibacy, moral restraint, etc. If people fail to check growth of population by the adoption of preventive checks, positive checks operate in the form of vice, misery, famine, war, disease, pestilence, floods and other natural calamities which tend to reduce population and thereby bring a balance with food supply.

According to Malthus, preventive checks are always in operation in a civilized society, for positive checks are crude. Malthus appealed to his countrymen to adopt preventive checks in order to avoid vice or misery resulting from the positive checks.

Malthus doctrine is illustrated below.Malthusian definition is - of or relating to Malthus or to his theory that population tends to increase at a faster rate than its means of subsistence and that unless it is checked by moral restraint or disaster (such as disease, famine, or war) widespread poverty and degradation inevitably result.

Neo-Malthusian theory was advanced by Thomas Robert Malthus and it stated that the means of subsistence increases at a ratio of arithmetic while the population . A Malthusian growth model, sometimes called a simple exponential growth model, is essentially exponential growth based on the idea of the function being proportional to the speed to which the function grows.

The model is named after Thomas Robert Malthus, who wrote An Essay on the Principle of Population (), one of the earliest and most influential books on population.

Theories of Population: Malthus Theory, Marx’s Theory and Theory of Demographic Transition! The theorizing about population (population size and change) have remained an important subject since time immemorial.

Many of the ancient philosophers like Confucius (China), Kautilya (India), Ibn Khaldin.

The Malthusian Theory of Population is a theory of exponential population growth and arithmetic food supply growth. Thomas Robert Malthus, an English cleric, and scholar published this theory in his writings, An Essay on the Principle of Population.
