Overview of the Chapter: Population

This chapter explores the concept of population, its distribution, density, growth, and composition. It also discusses the factors influencing population change and the implications of population growth on resources and development.

Population: A group of individuals of the same species living in a particular geographical area at a given time.

Population Distribution and Density

Population distribution refers to how people are spread across the Earth's surface. Population density is the number of people per unit area, usually per square kilometer.

Population Density: Calculated as the number of people divided by the total area of the region.

Factors Affecting Population Distribution

  • Geographical factors: Climate, water availability, soil fertility, and mineral resources.
  • Social and cultural factors: Religious or cultural significance of a place.
  • Economic factors: Employment opportunities, industrialization, and urbanization.

Population Growth

Population growth is the change in the number of people living in a particular area between two points in time. It is influenced by birth rates, death rates, and migration.

Birth Rate: The number of live births per thousand people in a year.

Death Rate: The number of deaths per thousand people in a year.

Migration: The movement of people from one place to another for permanent or temporary settlement.

Population Composition

Population composition refers to the structure of the population in terms of age, sex, literacy, occupation, and health.

Age Composition

Divided into three groups:

  • Children (below 15 years)
  • Working-age (15-59 years)
  • Aged (60 years and above)

Sex Ratio

The number of females per thousand males in a population.

Implications of Population Growth

Rapid population growth can lead to:

  • Pressure on natural resources
  • Increased demand for food, housing, and healthcare
  • Environmental degradation

National Population Policy

The government of India has implemented policies to address population growth, focusing on family planning, health care, and education.

Short Answer (3 Marks) – with Solutions (CBSE Pattern)

These 3-mark questions require brief explanations and help assess understanding and application of concepts.

Question 1:
What is population density? How does it vary across different regions of India?
Answer:

Population density refers to the number of people living per unit area, usually per square kilometer.

In India, it varies widely due to factors like geographical features, climate, and economic opportunities. High-density regions include the Indo-Gangetic plains and coastal areas due to fertile land and urbanization. Low-density regions like the Himalayas and Thar Desert have harsh climates and limited resources.

Question 2:
Explain the term birth rate and its impact on population growth.
Answer:

Birth rate is the number of live births per 1,000 people in a year.

A high birth rate leads to rapid population growth, increasing demand for resources like food, education, and healthcare. Conversely, a declining birth rate, as seen in developed regions, can cause an aging population and labor shortages.

Question 3:
Describe the role of literacy in controlling population growth.
Answer:

Literacy, especially among women, plays a crucial role in population control.

Educated individuals are more aware of family planning, health, and career opportunities, leading to smaller families. For example, Kerala's high literacy rate correlates with its low population growth compared to less literate states.

Question 4:
What are the major factors influencing migration in India?
Answer:

Migration in India is influenced by:

  • Economic opportunities: People move to cities for jobs.
  • Education: Students relocate for better institutions.
  • Natural disasters: Droughts or floods force displacement.
For example, rural-to-urban migration is high due to industrialization.

Question 5:
How does age composition affect a country's economy?
Answer:

Age composition refers to the proportion of different age groups in a population.

A youthful population (more children) requires investment in education and healthcare, while an aging population increases healthcare costs and reduces workforce. A balanced age structure supports economic growth.

Question 6:
Differentiate between population distribution and population density with examples.
Answer:

Population distribution refers to how people are spread across an area (e.g., uneven in India due to geographical diversity).

Population density measures the number of people per unit area (e.g., high in cities like Mumbai, low in Arunachal Pradesh). Distribution shows patterns, while density quantifies concentration.

Question 7:
Explain the term birth rate and its significance in population studies.

Compare rural and urban population trends in India using census data (2011-2021).
Answer:
Case Context

We studied rural-urban migration patterns in class.

Historical/Geographical Analysis
  • Rural: Declining due to fewer farms and mechanization.
  • Urban: Rising as cities offer jobs (e.g., Mumbai, Bengaluru).
Current Relevance

Overcrowded cities face pollution, while villages lack infrastructure.

Question 12:
How do literacy and healthcare influence population quality? Use Kerala and Bihar as examples.
Answer:
Case Context

Our textbook links literacy and healthcare to population quality.

Historical/Geographical Analysis
  • Kerala: High literacy (94%) and healthcare lower infant mortality.
  • Bihar: Low literacy (62%) and poor healthcare raise fertility rates.
Current Relevance

Government schemes like Ayushman Bharat aim to bridge these gaps.

Question 13:

The village of Rampur has a population of 5,000 people. The birth rate is 25 per 1,000, and the death rate is 10 per 1,000. Calculate the natural growth rate of the population. Also, explain two factors that might influence this growth rate in rural areas like Rampur.

Answer:

The natural growth rate is calculated as the difference between the birth rate and death rate.

Birth rate = 25 per 1,000
Death rate = 10 per 1,000

Natural growth rate = Birth rate - Death rate = 25 - 10 = 15 per 1,000.

Two factors influencing this growth rate in rural areas like Rampur are:

  • Healthcare facilities: Limited access to hospitals or clinics may lead to higher death rates, while improved healthcare can reduce mortality.
  • Literacy and awareness: Lower literacy rates may result in higher birth rates due to lack of family planning awareness.
Question 14:

Study the population pyramid of Country X given below (assume a broad base narrowing towards the top). Identify the type of population growth it represents and explain two challenges this country might face due to its population structure.

Answer:

The population pyramid with a broad base and narrow top indicates a high birth rate and high population growth, typical of a developing country.

Two challenges this country might face are:

  • Pressure on resources: A large young population requires more schools, jobs, and healthcare, straining the economy.
  • Unemployment: Rapid population growth may lead to a shortage of jobs, increasing poverty and social issues.
Question 15:
The table below shows the population distribution of India in 2021 across different age groups. Analyze the data and answer the following questions:

Age Group (Years) | Population Percentage
0-14 | 26%
15-59 | 62%
60+ | 12%

a) Identify the dependency ratio in this scenario.
b) What implications does this age structure have on India's economy?
Answer:

a) The dependency ratio is calculated by adding the young (0-14) and elderly (60+) population and dividing by the working-age population (15-59), then multiplying by 100.

Formula: Dependency Ratio = (Young Population + Elderly Population) / Working-Age Population × 100

Calculation:
Young Population = 26%
Elderly Population = 12%
Working-Age Population = 62%

Dependency Ratio = (26 + 12) / 62 × 100 = 38 / 62 × 100 ≈ 61.3%

b) Implications of this age structure:

  • Economic Growth: A high working-age population (62%) indicates a potential demographic dividend, boosting productivity if properly skilled.
  • Healthcare Pressure: The 12% elderly population may strain healthcare systems due to age-related diseases.
  • Education Demand: 26% young population requires investment in schools and child welfare schemes.
  • Employment Challenge: Creating jobs for the large working-age group is critical to avoid unemployment.

Question 16:
Rural-urban migration in India has led to overcrowding in cities like Mumbai and Delhi. Study the given case and answer:

a) List two push factors driving migration from villages.
b) Suggest two measures to reduce migration by improving rural conditions.
Answer:

a) Two push factors from villages:

  • Lack of Employment: Limited job opportunities in agriculture or small-scale industries force people to move.
  • Poor Infrastructure: Absence of schools, hospitals, and roads makes rural life challenging.

b) Measures to reduce migration:

  • Skill Development: Train villagers in non-farming skills (e.g., handicrafts, dairy farming) to create local jobs.
  • Infrastructure Boost: Improve rural roads, healthcare, and digital connectivity to enhance quality of life.

Additional Insight: Government schemes like MGNREGA (rural employment guarantee) and PM Awas Yojana (housing) can also stabilize rural populations.

Question 17:
Read the following case study and answer the question:

Rural Area X has a high birth rate due to lack of education and early marriages, while Urban Area Y has a declining birth rate due to awareness and family planning. Both areas are in the same state but show contrasting population trends.

Analyze the factors responsible for the difference in birth rates between the two areas and suggest measures to balance population growth.
Answer:

The difference in birth rates between Rural Area X and Urban Area Y can be attributed to several factors:

  • Education: Urban areas have better access to education, especially for women, leading to awareness about family planning.
  • Economic Conditions: Urban populations often prioritize careers over early marriages, reducing birth rates.
  • Healthcare Facilities: Urban areas have better access to contraceptives and healthcare services.
  • Cultural Practices: Rural areas may still follow traditional norms promoting early marriages and larger families.

To balance population growth, the following measures can be taken:

  • Promote education and awareness programs in rural areas.
  • Improve access to healthcare and family planning services.
  • Encourage women empowerment to delay marriages and childbirth.
  • Implement government policies supporting smaller families through incentives.
Question 18:
Study the population pyramid of Country A (expanding) and Country B (stable) given below. Compare the two pyramids and explain the implications of each on the country's economy and society.
Answer:

Country A (Expanding Population Pyramid):

  • Wide base indicates a high birth rate and youthful population.
  • Implications:
    - High demand for education and employment opportunities.
    - Strain on resources like healthcare and infrastructure.
    - Potential for a future demographic dividend if managed well.

Country B (Stable Population Pyramid):

  • Nearly equal distribution across age groups indicates balanced birth and death rates.
  • Implications:
    - Stable workforce supporting the economy.
    - Better resource allocation due to controlled population growth.
    - Aging population may require pension schemes and elderly care.

Overall, Country A faces challenges of rapid growth, while Country B benefits from stability but must prepare for an aging population.

Question 19:
Read the following case study and answer the question:

Rural Area X has a high birth rate due to lack of education and early marriages, while Urban Area Y has a declining birth rate due to awareness and family planning. Both areas are in the same state but show contrasting population trends.

Question: Explain the factors responsible for the difference in birth rates between Rural Area X and Urban Area Y. How does this impact the overall population growth of the state?
Answer:

The difference in birth rates between Rural Area X and Urban Area Y can be attributed to several factors:

  • Education: Urban areas have better access to education, especially for women, leading to awareness about family planning and delayed marriages.
  • Economic Conditions: Urban populations often prioritize careers and financial stability over early childbearing, unlike rural areas where children are seen as additional labor.
  • Healthcare Facilities: Urban areas have better access to contraceptives and healthcare services, reducing unplanned pregnancies.
  • Cultural Norms: Rural areas may follow traditional practices promoting larger families, while urban lifestyles favor smaller families.

This contrast impacts the state's overall population growth by creating an imbalance. While rural areas contribute to higher population growth, urban areas stabilize it. The state must focus on education and healthcare in rural regions to achieve sustainable population growth.

Question 20:
Analyze the given data and answer the question:

State A has a high population density due to fertile land and industrial opportunities, while State B has low density due to harsh climate and limited resources.

Question: How do geographical and economic factors influence population distribution in these states? Suggest one measure each to balance population distribution.
Answer:

Geographical and economic factors play a crucial role in population distribution:

  • State A attracts people due to fertile land for agriculture and industrial jobs, leading to high density.
  • State B has low density because of its harsh climate (e.g., deserts or mountains) and scarce resources, making survival difficult.

To balance population distribution:

  • For State A: Encourage decentralization of industries to other regions to reduce overcrowding.
  • For State B: Improve infrastructure (like water supply and roads) to make the region more habitable and economically viable.

These measures can help achieve a more balanced population distribution across both states.

Question 21:
The table below shows the population distribution of India in 2021 across different age groups. Analyze the data and answer the questions that follow:

Age Group (Years) | Population Percentage
0-14 | 26%
15-59 | 62%
60+ | 12%

(a) Identify the dependency ratio in the given data.
(b) How does this age structure impact India's economic growth?
Answer:

(a) The dependency ratio is calculated by adding the percentage of the population aged 0-14 (26%) and 60+ (12%), then dividing by the working-age population (15-59, 62%).

Dependency Ratio = (26 + 12) / 62 = 38/62 ≈ 0.61 or 61%.

This means there are approximately 61 dependents for every 100 working-age individuals.

(b) The age structure shows a large working-age population (62%), which is favorable for economic growth due to:

  • Higher productivity as more people are employed.
  • Increased savings and investments due to fewer dependents.
  • Potential for a demographic dividend if proper education and job opportunities are provided.
However, if the dependent population (especially children) grows faster, it may strain resources like education and healthcare.

Question 22:
Rural-to-urban migration is increasing in India due to various factors. Study the given case and answer the questions:

Case: A farmer from Bihar migrates to Mumbai in search of better employment opportunities but ends up living in a slum with poor sanitation.

(a) What are the push and pull factors in this scenario?
(b) Suggest two measures to reduce such distress migration.
Answer:

(a) In this case:

  • Push factors (reasons to leave rural areas):
    - Lack of employment opportunities in agriculture.
    - Low income and poverty in villages.
    - Poor infrastructure like schools and hospitals.
  • Pull factors (attractions of cities):
    - Better job opportunities in industries/services.
    - Higher wages compared to rural areas.
    - Access to education and healthcare facilities.

(b) Measures to reduce distress migration:

  • Rural development programs like MGNREGA to provide employment in villages.
  • Improving agricultural infrastructure (irrigation, storage) to increase farmers' income.
  • Promoting small-scale industries in rural areas to create local jobs.
  • Enhancing education and healthcare facilities in villages to reduce urban attraction.
