Comparison of Population Density: India and Bangladesh

Introduction:
Population density is a measure of the number of people per unit area. It is calculated by dividing the total population of a country by its land area. In this question, we are comparing the population density of India with that of several other countries.

Comparison:
Among the given options, Bangladesh has a lower population density than India. Let's explore this further:

Population:
- India: As of 2021, India has a population of approximately 1.3 billion people, making it the second most populous country in the world.
- Bangladesh: On the other hand, Bangladesh has a population of around 165 million people, making it the eighth most populous country in the world.

Land Area:
- India: India has a land area of about 3.29 million square kilometers, making it the seventh largest country in the world by land area.
- Bangladesh: In contrast, Bangladesh has a much smaller land area of about 147,570 square kilometers, making it one of the smaller countries in the world.

Calculating Population Density:
To calculate the population density, we divide the population of a country by its land area:

- India: Population density of India = Population of India / Land area of India = 1.3 billion / 3.29 million square kilometers ≈ 393 people per square kilometer.
- Bangladesh: Population density of Bangladesh = Population of Bangladesh / Land area of Bangladesh = 165 million / 147,570 square kilometers ≈ 1,118 people per square kilometer.

Conclusion:
Comparing the population densities, we can see that Bangladesh has a higher population density than India. While India has a population density of approximately 393 people per square kilometer, Bangladesh has a higher population density of around 1,118 people per square kilometer. Therefore, the correct answer is option 'B' - Bangladesh.
