Malthusian Theory(Robert Malthus)
- the earliest population theory which co-related population explosion with food crisis. It is deterministic & predictive theory of demographic changes.
- Malthus theory is termed as Naturalist Theory because it suggested the nature's mechanism as a control for population and an automated response to the society to control the population.
- Malthus suggested that the population grows at the exponential rate or geometric progression and food grows at asthmatic rate.
Population = 1, 2, 4, 8, 16, 32, 64, 128, 256,.......
Food = 1, 2, 3, 4, 5, 6, 7, 8, 9.......
- Population doubles itself in every 25 years
- After 200 years the ratio of food & population reaches a critical point where a world crisis will take place & eventually by natural force, food crisis, or civil war population size will be brought back to the pre-industrial level.
- the critical ratio is 256:9

- Malthus suggested 2 control measures:
