T. Malthus propounded one of the most famous theories, called 'The Malthusian Theory' which is related to?

Option 2 : Population

The correct answer is Population.

Malthusian Theory of Population

• The Malthusian Theory of Population is the theory of exponential population and arithmetic food supply growth.
• The theory was proposed by Thomas Robert Malthus.
• He believed that a balance between population growth and food supply can be established through preventive and positive checks.
• Malthus's theory states that:
  • The population is necessarily limited by the means of subsistence.
  • Population invariably increases where means of subsistence increase, unless prevented by some very powerful and obvious checks.
  • These checks, and the checks which repress the superior power of the population and keep its effects on a level with the means of subsistence, are all resolvable into moral restraint, vice and misery.
• Malthus based his above arguments on man’s two basic characteristics essential to the maintenance of life:
  1. The need for food
  2. The passion between sexes.
• It was the second which led people to marry at a relatively early age and would result in such a large number of births that the population would double itself in a few years if unchecked by misery and vice.
