What is Population Density?

Hint: Population Density is an important geographical term. Monaco has the highest population density in the world.Greenland has the lowest.

Complete answer: The number of people living in an area of per square kilometres is called population density.This shows how crowded a place is.There are a number of factors that can affect the population density.They are:
1. Physical factors like the climate, relief, water supply, transportation, availability of natural resources and energy.
2.Social, political and economic factors.
3. Healthcare standards, employment opportunities
4. Education
Human discomfort, remote areas and inaccessibility are the major causes of low popu;lation density. Explaining the factors:
Relief and climate: The plains and fertile areas are more prone to be inhabited than mountainous areas that have poor quality soil and are steep and have low population density.
Weather and climate: Temperate areas which do not experience extreme weather conditions have a higher population density than cold, dry areas have low density.
Economic opportunities: Regions which do not have much economic opportunities have low density because most people are unable to secure a regular income. Regions with economic opportunities have a higher density.
Advance and affordable education and healthcare are the other important factors.Good healthcare systems help reduce mortality rates. Better education provides for economic growth. In these areas population density is high.

Note: In India West Bengal has the highest population density and Arunachal Pradesh has the lowest population density. While answering the question do not get confused between population density and population distribution.
