NCERT Class 12 Geography Fundamentals of Human Geography: Chapter 2 — The World Population Distribution, Density and Growth
This chapter from NCERT's Fundamentals of Human Geography, Class 12, focuses on the distribution, density, and growth of the world's population. It begins by emphasizing that people are a nation's true wealth and resources. The chapter explores why populations are unevenly distributed across the globe, highlighting that 90% of the world's population lives on only 10% of the land area. It delves into the factors influencing population distribution, categorizing them into geographical factors (water availability, landforms, climate, soils) and economic factors (minerals, urbanisation, industrialisation). The concept of population density is defined and calculated as the ratio between population and land area. Understanding these patterns is crucial for analyzing demographic characteristics and planning for future development.

Vocabulary
| Word | Meaning |
|---|---|
| Population Distribution | The way people are spaced over the earth's surface. |
| Population Density | The ratio between the numbers of people to the size of land, usually measured in persons per sq km. |
| Urbanisation | The process of cities growing in size due to migration and offering better employment, education, and facilities. |
| Industrialisation | The development of industries, which provides job opportunities and attracts large numbers of people. |
| Landforms | The shape of the land, which can be favourable or unfavourable for human settlement and development. |
| Climate | The long-term weather patterns in an area, influencing human comfort and habitation. |

Practice questions
- What is the most important factor for life, influencing population distribution? Answer: Availability of water.
- Why do people prefer living on flat plains and gentle slopes? Answer: These areas are favourable for crop production and building infrastructure like roads and industries.
- How does urbanisation influence population distribution? Answer: Cities offer better employment, education, and facilities, attracting people and leading to dense populations in urban areas.
- Define population density. Answer: Population density is the ratio between the number of people and the size of land, usually expressed as persons per square kilometer.
Practice MCQs
Q1. Which of the following is a geographical factor influencing population distribution?
Explanation: Availability of water is a fundamental geographical requirement for human settlement and activities.
Q2. The remark 'Asia has many places where people are few and few places where people are very many' is attributed to:
Explanation: George B. Cressey made this observation about the population distribution in Asia, which is also applicable to the world.
Q3. Which type of landform is generally less populated due to hindrances in development?
Explanation: Mountainous and hilly areas make transport network development difficult, hindering agricultural and industrial growth, thus leading to lower population.
Q4. What percentage of the world's population lives in about 10% of its land area?
Explanation: The text states that broadly, 90 per cent of the world population lives in about 10 per cent of its land area.
Q5. Which economic factor attracts industries and generates employment, leading to dense populations?
Explanation: Areas rich in mineral deposits attract mining and industrial activities, creating jobs and drawing people to settle there.
Frequently asked questions
What is the main idea of Chapter 2 of Fundamentals of Human Geography?
The chapter focuses on the uneven distribution, density, and growth of the world's population, and the geographical and economic factors that influence these patterns.
What are the key geographical factors affecting population distribution?
The key geographical factors include availability of water, landforms, climate, and soils.
What are the main economic factors that influence where people live?
The main economic factors are the presence of minerals, urbanisation (cities offering opportunities), and industrialisation (industrial belts providing jobs).
How is population density calculated?
Population density is calculated by dividing the total population of an area by its total land area, usually expressed as persons per square kilometer.
Why are river valleys often densely populated?
River valleys are densely populated because they provide easy access to fresh water, which is essential for drinking, agriculture, and other human activities.
