A. population density
B. Malthusian population theory
C. national population theory
D. demographical transition theory

Correct Answer:

Option B – Malthusian population theory

Explanation

The Malthusian population theory highlights the relationship between population and means of subsistence. The main features of Malthusian theory about population are:

i. That population was growing at a geometric progression such as 2,4,6,8,16,32, etc, while food production or supply was growing at an arithmetical progression such as 1,2,3,4,5, etc.
ii. That there is a tendency for all living things to grow beyond the food available to them
iii. That unless population increase is matched with means of subsistence, negative and positive checks will come into force.
iv. That the checks can be war, diseases, epidemics and famine.
v. That population is essentially limited by the means of subsistence.
