Population Density

Population density measures the number of individuals (people, animals, plants, microorganisms) per unit volume (water, air, or soil) or area. It is a statistic that indicates the number of people living in a certain area.

Population density refers to the number of people living in an area per square kilometer. Population density is calculated by dividing the number of people by square kilometer area.

What are the Factors affecting Population Density?

Following are some factors that affect the population density:

  1. Geographical factors: Plain areas are densely populated as these areas are suitable for agriculture, manufacturing, and service activities.
  2. Climate: Areas of extreme climates are loosely populated as people generally stay away from these areas. People prefer to live in areas where there is fertile soil and in places where fresh water is easily available.
  3. Places with better health facilities, better housing, and education are more densely populated.
  4. Places of religious importance are usually densely populated.
  5. Places where there is the availability of jobs and economically active areas are densely populated.

What are the Advantages of High Population Density?

  1. Higher population density can help reduce the typical costs of the transport network.
  2. The rising population will produce entrepreneurs and innovators as it leads to a greater scope of society.
  3. High population density places will see stronger economic growth.
  4. Diversity will be more in high population density areas.
  5. Urban areas are more energy efficient when compared to rural areas.

What are the Disadvantages of High Population Density?

  1. An increase in population can lead to the exploitation of natural resources.
  2. High population density can result in low per capita income.
  3. Due to an increase in population density, there can be a lack of employment opportunities.
  4. There will be congestion in the transportation network.
