![]() Preventive check: This check involves consciously postponing marriage and reproduction because of a shortage of resources. ![]() Malthus gave two types of ‘checks’ that prevent population growth based on resource supply. The growth can lead to a reduction in the food supply. For example, 3,6,9 is an arithmetic progression with the common difference being 3.įrom this, Malthus concluded that population growth will be faster than resource production. An arithmetic progression is an order of numbers in which the difference between the consecutive numbers is the same. For example, 2,4,8,16 is a geometric progression with 2 being the common ratio.Īccording to him, resource production increases by arithmetic progression. The geometric progression is an order of numbers (excluding zero) wherein each number after the first is multiplied by the previous one by a fixed number (excluding zero) called the common ratio. ![]() Malthus stated that the population grows through geometric progression. He assumed that the growth would be disastrous and he should warn the fellow-countrymen about the state of the economy due to the population growth. His opinions were coloured by the increased population growth in England. He looked at the economy in a pessimistic manner and viewed poverty as unavoidable. Malthus believed that the population will continue to outrun the growth of resources. ![]() This theory is based on the idea that the population is becoming more and more rapid, but there are not enough resources to satisfy this exponential population. Thomas Robert Malthus was a well-known economist who developed population growth theories and mentioned them in his book, ‘An Essay on the Principle of Population.’ He developed the Malthusian theory of population. ![]()
