Question

Write a short note on population density.

Answer 1

Instructions:

• Define population density.
• Give an example
• Mention cities with high and low population density in India​

Solution:
Population density is the measure of the number of individuals living within a specific area. To determine population density, the number of individuals is divided by the size of the area. ​
Formula:
Population density = Number of people/ Land area

• Suppose, there are 2 pieces of land named Land A and Land B with the same area of 1 sq km. 85 people reside on land A and 100 people reside on land B. ​
• Land B is more populated as it has more people.​

According to the 2011 census, India has 382 people per sq km.​ Bihar has the highest population density whereas Arunachal Pradesh has the lowest population density.
