Malthusian Theory of Population
Propounded by T.R. Malthus in his famous book “An Essay on Principle of Population”,1798Population growth rate rises at a faster rate than theproduction of food or food supply
According to Malthus," By nature, human foodincreases in a slow arithmetic ratio; men himselfincreases in a quick geometrical ratio unless want and vice stop him.”

Features of Malthusian Theory
Population Growth Rate
Food Supply
Imbalance between Population and Food Supply
Checks on Population
Preventive Checks
Positive Checks

Criticisms of Malthusian Theory
Wrong Numerical Ratios
Positive Checks not a symptom of Over
population
Pessimistic Theory
Ignores modern means of birth control

Summary of Malthusian Theory
MALTHUSIAN THEORY OF POPULATION
Population increases in geometrical progression
Population increases in arithmetical progression
Results in imbalance betweenPopulation and food supply
Correction of Imbalance
Preventive Checks- late marriage, celibacy,
etc.
Positive Checks- famines, epidemics, war, etc.
Preventive Checks is the best

Optimum Theory of Population
Propounded by economist live Sedgwick, Cannon,
Dalton, etc.
Not a complete contrast of Malthusian Theory but an
improved version
Consider that the certain rise in population is
beneficial for the utilization of productive resources

Is Nepal Overpopulated?
Not overpopulated in the sense of optimum theory
More resources than the population
Only lack of utilization of resources
