Answer 1: (i) Why are people considered a resource?
People are considered a resource because they possess skills, knowledge, creativity, and labor that contribute to economic, social, and cultural development. Human resources drive innovation, productivity, and the efficient utilization of natural resources, making them essential for the growth and sustainability of societies.
(ii) What are the causes for the uneven distribution of population in the world?
The uneven distribution of population in the world is due to several factors, including:
- Geographical factors: Favorable climates, fertile land, and water availability attract populations, while deserts, mountains, and extreme climates deter settlement.
- Economic factors: Areas with industries, job opportunities, and better infrastructure have higher population densities.
- Social and political factors: Political stability, healthcare, education, and social amenities influence population distribution. Conflict-prone regions tend to have lower population densities.
(iii) The world population has grown very rapidly. Why?
The world population has grown rapidly due to:
- Declining death rates: Advances in medicine, healthcare, and sanitation have reduced mortality rates.
- Increased birth rates: In some regions, cultural and economic factors encourage high birth rates.
- Improved food production: Agricultural advancements have led to better food security, supporting larger populations.
(iv) Discuss the role of any two factors influencing population change.
- Birth Rate: High birth rates lead to population growth, while low birth rates contribute to population stabilization or decline. Factors like education, healthcare, and family planning influence birth rates.
- Migration: Movement of people from one region to another affects population distribution. Immigration increases population in the receiving area, while emigration decreases it in the source area. Economic opportunities, political stability, and environmental conditions drive migration.
(v) What is meant by population composition?
Population composition refers to the structure of the population of a particular region. The composition of a population helps us to know the number of males and females comprising the population, their age groups, educational and technological skills, occupations, income levels, health conditions, etc.
(vi) What are population pyramids? How do they help in understanding about the population of a country?
The graphical representation used to study the composition of a country’s population is called the population pyramid. It shows the total population divided into various age groups, the percentage of the total population subdivided into males and females and the number of dependents in a country. When the population of a country has high birth and death rates, the population pyramid is broad at the base and narrow towards the top.

Question 2: In 1999, the world population reached
(a) 1 billion
(b) 3 billion
(c) 6 billion
Answer 2: (c) 6 billion
Question 2: What is a population pyramid?
(a) A graphical presentation of the age, sex composition of a population.
(b) When the population density of an area is so high that people live in tall buildings.
(c) Pattern of population distribution in large urban areas.
Answer 2: (a) A graphical presentation of the age-sex composition of a population
Question 3: Complete the sentences below using some of the following words.
(sparsely, favourable, fallow, artificial, fertile, natural, extreme, densely)
When people are attracted to an area, it becomes ………………….. populated. Factors that influence this include ………………….. climate, good supplies of ………………….. resources and ………………….. land.
Answer 3: When people are attracted to an area, it becomes densely populated. Factors that influence this include favourable climate, good supplies of natural resources and fertile land.
Question 4: Activity
Discuss the characteristics of a society with ‘too many under 15s’ and one with ‘too few under 15s’.
Hint : need for schools; pension schemes, teachers, toys, wheel chairs, labour supply, hospitals.
Answer 4: The society with too many under 15s need more schools to be able to educate them. There should be efficient and laborious teachers. There should be provisions for items necessary for a child’s amusement, like toys. Children are prone to diseases; facilities for hospitals should be improved in such a society.
In a society with too few under 15s will have more and more mature people. Pension schemes will work there fruitfully. There may be the need for wheelchairs. Labour supply will be easier. These people will also need hospitals.
