Density of Population
Density of population is a measure that expresses the number of people living per unit area of land, usually per square kilometer. It is an important demographic indicator that helps understand how crowded or sparsely populated a region is. The formula for calculating population density is the total population divided by the total land area. For example, if a region has an area of 100 square kilometers and a population of 150,000 persons, the population density would be 150,000 ÷ 100 = 1,500 persons per square kilometer. This indicates a very high concentration of people in that region. Population density helps planners and policymakers in resource allocation, infrastructure development, and urban planning. However, density alone does not reveal the quality of life or distribution within the area; some parts may be densely populated while others are empty. Understanding density along with distribution patterns gives a clearer picture of human settlement.
📊 Diagram: No specific diagram in this section, but the example calculation illustrates the concept of population density.
🧪 Activity: Students calculate the population density of their own district or state using available data.
🔗 Connection: This section leads to the discussion of factors influencing population distribution and density, explaining why some areas are densely populated and others are not.
Frequently asked questions
1. Choose the right answer from the four alternatives given below. (i) Which one of the following continents has the highest growth of population? (a) Africa (b) South America (c) Asia (d) North America (ii) Which one of the following is not an area of sparse population? (a) The Atacama (b) South-east Asia (c) Equatorial region (d) Polar regions (iii) Which one of the following is not a push factor? (a) Water shortage (b) Medical/educational facilities (c) Unemployment (d) Epidemics (iv) Which one of the following is not a fact? (a) Human population increased more than ten times during the past 500 years. (b) Population growth is high in the first stage of demographic transition?
(i) Correct answer: (a) Africa Explanation: Africa has the highest population growth rate among continents due to high birth rates and improving mortality rates.
(ii) Correct answer: (b) South-east Asia Explanation: South-east Asia is a densely populated region, not sparse. The Atacama desert, equatorial regions (dense forests), and polar regions are sparsely populated.
(iii) Correct answer: (b) Medical/educational facilities Explanation: Medical and educational facilities are pull factors att
2. Answer the following questions in about 30 words. (i) Name three geographical factors that influence the distribution of population. (ii) There are a number of areas with high population density in the world. Why does this happen? (iii) What are the three components of population change?
(i) Three geographical factors influencing population distribution are: availability of water, climate, and landforms.
(ii) High population density occurs in areas with fertile land, favorable climate, and availability of water and resources.
(iii) The three components of population change are birth rate, death rate, and migration.
3. Distinguish between: (i) Birth rate and death rate. (ii) Push factors and pull factors of migration.
(i) Birth rate is the number of live births per 1000 people in a year, while death rate is the number of deaths per 1000 people in a year.
(ii) Push factors are conditions that drive people away from a place (e.g., unemployment, war), whereas pull factors attract people to a place (e.g., job opportunities, better living conditions).
4. Answer the following questions in about 150 words. (i) Discuss the factors influencing the distribution and density of population in the world. (ii) Discuss the three stages of demographic transition.
(i) Factors influencing population distribution and density include physical factors like climate, landforms, soil fertility, and availability of water. Favorable climate and fertile land support agriculture and human settlement. Economic factors such as industrial development, infrastructure, and employment opportunities attract people. Social and political factors like government policies, cultural aspects, and historical developments also influence population patterns. Areas with harsh climat
