According to Malthus, the population of a country grows

The correct answer is Geometrically

Key Points

Malthus' theory of population:

• Population and Food Supply: Malthus theorised that any population grows in geometric progression.
•  He believed that a balance between population growth and food supply can be established through preventive and positive checks.

Important Points Major Elements of the Malthusian Theory

Population and Food Supply: 

• The Malthusian theory provided an explanation for why population growth is geometric.
• At this rate, the population would double in 25 years. However, there is an arithmetic increase in the food supply.
• The amount of food available grows more slowly than the population. In other words, there won't be enough food in a few years.
• A growing population is indicated by the food supply shortfall.

Checks on Population:

• Disequilibrium occurs when there is a gap between the rate of population growth and the availability of food.
• People will therefore not have access to even enough food for survival. Due to a scarcity of food, many will perish.
• Malthus referred to the occurrence of adversities like epidemics, wars, starvation, famines, and other natural disasters as positive checks.
• Contrarily, there are artificial checks referred to as preventive checks.

Positive Checks:

• The natural world has its own mechanisms for regulating the expanding human population.
• It raises the population to the level at which food is readily available.
• Famines, earthquakes, floods, diseases, wars, etc. are examples of the positive checks.
• When population expansion becomes out of control, nature becomes more active.

Preventive Checks:

• Late marriage, self Control, and simple living are preventive strategies that help to balance population increase and food availability.
• These procedures not only limit population increase but also have the potential to avoid the terrible effects of positive checks.
