4) INTERNATIONAL PUBLICATION
SOURCES OF DEMOGRAPHIC DATA

consists of only a fraction of the total population
Source 3: Sample Surveys
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.
The Malthusian Theory of Population
Major Elements of the Malthusian Theory
The Malthusian theory explained that the population grows in a geometrical fashion.
1) Population and Food Supply
Major Elements of the Malthusian Theory
When the increasing population rate is greater than the food supply, disequilibrium exists. As a result, people will not get enough food even for survival.
Adversities such as epidemics, wars, starvation, famines and other natural calamities will crop up which are named as positive checks by Malthus. On the contrary, there are man-made checks known as preventive checks.
2) Checks on Population
Major Elements of the Malthusian Theory
Nature has its own ways of keeping a check on the increasing population. It brings the population level to the level of the available food supply.
include famines, earthquakes, flood, epidemics, wars, etc. Nature plays up when the population growth goes out of hand.
3) Positive Checks
Major Elements of the Malthusian Theory
measures such as late marriage, self-control, simple living, help to balance the population growth and food supply. These measures not only check the population growth, but can also prevent the catastrophic effects of the positive checks
4) Preventive Checks
