Theories of Population Growth and Their Implications

The video tutorial by Mini Sethi covers three main theories of population: Malthusian theory, Demographic Transition Theory, and Optimum Theory of Population. The Malthusian theory discusses the imbalance between population growth and food supply, introducing positive and preventive checks to control population. The Demographic Transition Theory explains the shift from high birth and death rates to lower rates as economies industrialize. The Optimum Theory of Population, proposed by Edwin Cannon, identifies the ideal population size for maximizing resource utilization and per capita income. Each theory is explained with diagrams and examples.

What are the three main theories of population discussed in the video?

• Malthusian, Demographic Transition, Optimum

• Malthusian, Economic Growth, Optimum

• Demographic Transition, Economic Growth, Optimum

• Malthusian, Demographic Transition, Economic Growth

According to Malthus, how does the population growth rate compare to the food supply growth rate?

• Population grows faster than food supply

• Population grows at the same rate as food supply

• Population grows slower than food supply

• Population growth is unrelated to food supply

What are positive checks according to Malthusian theory?

• Strategies to enhance economic growth

• Techniques to improve food supply

• Situations that shorten human lifespan

• Methods to increase birth rates

What is the main focus of the Demographic Transition Theory?

• The impact of industrialization on birth and death rates

• The relationship between food supply and population

• The ideal size of population for resource utilization

• The effects of economic growth on population

During which stage of the Demographic Transition Theory are both birth and death rates high?

• First stage

• Second stage

• Fourth stage

• Third stage

What happens to birth and death rates as a country becomes more industrialized according to the Demographic Transition Theory?

• Birth rate decreases, death rate increases

• Both rates decrease

• Both rates increase

• Birth rate increases, death rate decreases

Who proposed the Optimum Theory of Population?

• Thomas Malthus

• Edwin Cannon

• Adam Smith

• David Ricardo

What does the Optimum Theory of Population aim to determine?

• The most industrialized population

• The slowest growing population

• The ideal size of population for maximum resource utilization

• The fastest growing population

What is the result of having a population size larger than the available resources according to the Optimum Theory?

• Unchanged per capita income

• Stable per capita income

• Decreased per capita income

• Increased per capita income

What is the main consequence of underpopulation according to the Optimum Theory?

• Per capita income increases

• Resources are overutilized

• Population growth accelerates

• Resources are underutilized
